following is the pertinent failure Quick and problem-solving
computer malfunction causes confusing, intangible. And because the Windows operating system components is relatively complex, computer accident of a failure, for the average user, you want to needlepoint the reasons for its failure is nearly impossible. So it is that if we experience computer failure, completely helpless out? This is not so, the computer-generated although there are many reasons for failure, but if we look carefully, conscientiously sum up, we can still have some computer failures of the law and approach. In this booklet, we will some of the most common and most typical computer fault diagnosis, maintenance methods show you, through it, you will find - ways to solve computer failure on your side, simple, but telling!
a motherboard
board is a key component of the computer, the computer plays a vital role. If the board will have problems affect the plenary PC computer system work. Here, we take a look at the motherboard in the course of which the most common faults.
a common fault: no show boot
computer boot no display, we need to retard is the BIOS. Motherboard BIOS the hardware store major data, while the motherboard BIOS is part of the more vulnerable, easily damaged,
PULSERA BLANCA CON MEXICO, once damaged it will reason the system can not escape, the recurrence of such failures are generally due to the motherboard BIOS is caused by CIH virus damage (of lesson not rule out the motherboard can not run itself, occasion the system to malfunction.) General BIOS hard drive after the virus destroyed data will be lost, so we can detect the hard disk data is intact to determine whether the BIOS is damaged, whether the hard disk data intact, so there are three reasons why the phenomenon of power no display:
1. because the motherboard or expansion card expansion slot problems, leadership to plug expansion cards like sound cards, etc. without the display after the board did not answer.
2. motherboard jumper settings in the CMOS the CPU frequency does not, may also lead to not show fault, which, as long cleared CMOS to be addressed. Clear CMOS jumper on the motherboard commonly approximate the power cell, in its default place is 2 short, at the peak of 3 to change it bound a few seconds to solve the problem short, should the old board for the before user can not ascertain to the jumper, fair clear the power cell, enter the CMOS settings to be displayed after the boot off, will work up also reached the CMOS battery on dismiss purposes.
3. motherboard does not recognize the memory,
PULSERA AZUL CON LOGO XB, memory corruption or memory does not match the boot no display can lead to failure. Some older motherboards more selective memory, once the plug in the motherboard does not acknowledge the memory, the motherboard will not start, and even some motherboards do not give you any fault tips (tweet). Of course sometimes in order to distend the memory to improve system performance, plug in the results of different brands, types of memory will also outcome in the emergence of such a failure, so maintenance should disburse more attention.
for the failure of the motherboard BIOS is damaged, we can plug in the ISA card to see whether the display (if prompted, can prompt steps below.), if I were you the boot screen, you can own do an auto update the BIOS floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try using hot method to solve (I have tried, at the peak of the BIOS the same, motherboard at the same class can be successful writer.) However, in addition to the use of hot things, need the same BIOS part of the motherboard components can cause damage, so a reliable method is to write code reader with a BIOS update files will be written inside the BIOS (this service can be to find a safer computer affair solutions).
two common faults: CMOS settings can not be saved
Such failures are generally due to insufficient battery voltage board, which can be replaced, but some motherboard battery replacement also can not solve the problem, at this time There are two possibilities:
1. motherboard perimeter problems, which are seeing for professional service;
2. motherboard CMOS jumper problem, sometimes because of the error will jump on the motherboard CMOS line set to clear the option, or set to one external battery, making the CMOS data can not be saved.
Troubleshooting III: In Windows, install the motherboard driver CD-ROM drive after crash or slow down the phenomenon
in some no-name motherboard sometimes these phenomena occur, the motherboard drivers Bahrain program, restart your computer can not enter the Windows 98 desktop in normal mode, and the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers installed, the problem usually can be resolved, if it is not, only to re-install the system.
Troubleshooting four: Install the Windows or start Windows when the mouse is not available
recurrence of such failures because the software is generally caused due to the CMOS settings wrong. Power management settings in the CMOS column has a modem use IRQ project, his options are 3,4,5 ......, NA,
Xtreme Balance, generally it is the default option is 3, set it to 3 other than intervene keys.
Common Fault 5: Frequent computer crashes, during the CMOS settings will crash phenomenon
crash phenomenon occurs in CMOS, usually the motherboard or CPU problem, should the press law does not troubleshooting, it can only replace the motherboard or CPU.
recurrence of such failures are generally due to a problem or motherboard motherboard Cache heat caused by bad design, I had base on the 815EP motherboard is not good ample for the motherboard heat caused the failure phenomenon. In touch after the crash motherboard components approximately the CPU, base that the temperature is quite peppery. After replacing the high-power fans, crash failures can be resolved. Cache problem for the failure, we can enter the CMOS setup, the Cache can repair the problem after the ban, of course, Cache weakened, the speed would surely be affected.
Troubleshooting Six: board COM wharf or parallel port, IDE interface failure
recurrence of such failures are generally due to causes related hardware hot plug the user, the user is able to use multi-function card instead of , but must be replaced before the ban comes on board COM port and parallel port (some motherboards with the IDE port to be banned for appropriate use).
graphics
common faults one: boot no display
Such failures are generally due to poor contact with the motherboard or graphics slot motherboard causing problems. Fknow next to nothing ofme integrated graphics motherboard, main memory if the shared memory, you need to pay attention to memory location, usually in the first memory slot should be inserted in the memory. As the card causes boot no display failure, power is generally given after a long two short beeps (in terms of graphics for AWARD BIOS).
Troubleshooting II: display the video, see the clear manuscript
such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to secure mode, under Windows 98 and then into the display settings, the 16-color mode click on the Restart in normal mode Windows 98 system, delete the graphics drivers, restart the computer. Or not to enter safe mode, in a pure DOS environment, edit
SYSTEM.INI file, display.drv = pnpdrver to display.drv = vga.drv after save and exit, then drive in Windows Update
program.
Troubleshooting III: color display is not normal, such failures are generally the following reasons:
1. display card and monitor marking line bad
2. monitor their own fault
3. in Some software to run when the color is not normal, usually common in older machines, there is a check in the BIOS, the color options to open it to
4. Graphics damage;
5. display is magnetized, Such phenomenon is generally due to magnetic objects can be caused by too close after magnetization may also cause screen appears deflection phenomenon.
Fault IV: Death
recurrence of such failures are generally more common in motherboards and graphics cards are not compatible with the graphics card or motherboard is bad; graphics card is not compatible with other extensions can also cause crashes .
Common Fault 5: abnormal noise or screen pattern
such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Need to clean or replace the card deceive site was
card.
Troubleshooting Six: graphics card driver is missing
graphics driver to load and run automatically after a period of driver detriment, such failures are generally due to poor quality or graphics card and motherboard do not compatible, making the graphics card temperature is too high,
PULSERA BLANCA CON ITALIA, causing the system unstable or crash, then only replace the movie card.
In addition, there is a special variety of position before to load the graphics driver, merely in the graphics drivers fraught into Windows when the break happened. Can replace other types of cards, after loading the driver, insert the old card to be addressed. Should such a failure can not be determined, then the registry failed, to restore the registry or reinstall the operating system can be.
Troubleshooting a sound card: sound speechless. There are common causes of this failure:
1. Driver default output to Click the base right turn of the sound icon (a small horn), appear to modify the volume slider, below the
2. sound card collide with other cards. The solution is to adjust the PnP cards used by system resources, so that all cards without confusing each other. Sometimes, open the
3. After installing the Direct X sound card can not be audible. Illustrate this sound card with Direct X compatibility is not good, need to update the driver.
4. one channel silent. Check the sound card to the speaker audio cord is loosened.
Troubleshooting II: sound card clamor is too colossal. There are common causes of this failure:
1. Card is not correct. As the chassis manufacturing accuracy is not high enough, the sound card manufacturer or installed outside the damper caused by bad sound card expansion slot can not be closely integrated with the motherboard, sound card can be seen visually on the This phenomenon in the ISA or PCI cards are, are common faults. Generally used pliers adjustment.
2. Active speakers Speaker input chained to the sound card output. For the athletic speaker, should be chained to the sound card Line out side, it has not been
output signal on the sound card amplifier noise is much smaller. There is only one sound output is still Speaker Line out jumpers on the card depends on the decision, the plant default mode is often Speaker, so the jumper to disconnect the sound card.
3. Windows comes with a bad driver. Sound card driver is installed, select list carton. If you have installed the Windows driver that comes with the optional Installation. Then insert the disk or CD-ROM with sound card, load the driver catered by the manufacturer.
Troubleshooting III: Sound can not I once had a sound card under Windows 98 with the original driver disk to install the drivers how can masquerade not to, and had to use Creative SB16 driver instead, everything is normal. Later upgrade to Windows Me, not behind to normal with Windows 2000 (full edition) comes with the sound card driver was normal.
2. The most difficult problem than the Windows 9X Plug and Play devices below test has chosen to given a free hand to aid you install the driver, the driver side is not used, then, every time you delete out reloading will reiterate this problem, and can not Here I reveal a mystery detached trick: Go to Win9xinfother classify, on the sound card then cancel all the *. inf file manually restart the installation after this a hundred percent efficacious, have saved countless lives ... ... of course, sound card, modify registration chart can attain the same purpose.
3. PnP sound card does not support the installation (also applies to not use the PnP mode PnP sound card installed): Go to Windows to quest for new hardware?
Troubleshooting four: Play CD silent
1. completely silent. With Windows 98, Use a 4-pin CD-ROM audio cable to connect the analog audio output and sound card CD-in to this line in the purchase of a CD-ROM will be included.
2. there is only one channel silent. I generally drive about two-wire output signal, the middle two lines to ground. As the audio signal line 4 line color is generally different from the color line to find one to one interface. If only one interface know next to nothing ofund card and audio cable for each interface does not match, had to change the order of the audio cable connection, usually only one of two lines of the change can be.
Troubleshooting five: PCI sound card sonic boom
generally because of the use of Bus Master PCI graphics card technology on the PCI bus caused by hanging hard disk read and write, mouse and other operations to distend the background
noise's sake. Solution: Turn off the Bus Master PCI card traits, and replaced with AGP graphics card, sound card for the PCI slot.
Common Fault 6: can not properly recording
first check whether there is naught erroneous with the microphone plugged into the other jack in the second, double-click the little speaker, choose list watch all the settings are correct. Then in the If the
Troubleshooting seven: Can not melodrama music, Wav, Midi Wav Music
can not play music are quite rare, often due to you can disable a; can not play MIDI files may have the following three possible:
1. Early ISA sound card may be due to 16-bit mode is not compatible with 32-bit mode cause MIDI playback is not normal, by installing Software wave table
way should resolve
2. Today, most of the popular PCI sound card with wavetable synthesis techniques using, if the MIDI playback is not part of it is probably because you do not have to load the appropriate wavetable sound library.
3. Windows volume control in the MIDI channel is set to silent mode.
Troubleshooting eight: PCI sound card is not properly used in WIN98
some users complained that the sound card driver installation process everything is normal, no device conflicts occur, but the following is not in the WIN98 out loud or if there were other failures. This phenomenon usually occurs on the PCI sound card, please check the installation process you plug in the PCI sound card which of the PCI slots. Some friends for thermal considerations, like the sound card plug away from the AGP slot, near the ISA slot that several PCI slots. Problems often arise here, because there is a Windows98 Bug: sometimes only the correct identification and inserted in the PCI-1 PCI-2 card slot two. ATX motherboard in two PCI is close to the AGP and PCI-1 PCI-2 (on the opposed in some of the ATX motherboard, close to the ISA is the PCI-1), so if you do not have the PCI sound card installed in the correct slot, the problem will have a.
memory computer memory is one of the most important parts, it is the role of doubt, the most common memory faults which have it?
a common fault: no show boot
memory because the recurrence of such failure is usually because the memory and the motherboard memory slot is bad cause, at a time smear his finger back and ahead with the eraser parts to solve the problem (do not use alcohol and other cleaning), there is memory corruption problem or motherboard memory slot can also cause such failures.
Because memory causes no show boot failure, host speakers typically have a long beep (for the Award Bios is concerned).
Troubleshooting two: Windows Registry damage often for no reason, users are prompted to restore
such as memory failures are generally caused by poor quality, difficult to be repaired, only replaced one way .
Troubleshooting III: Windows often automatically enter the secure mode
Such failures are generally due to the motherboard is not compatible with the memory or the memory caused by poor quality, common in high-frequency memory for Some do not support this frequency of memory on the motherboard, you can try to reduce the memory within the CMOS settings to see whether the read speed to solve the problem, should not do, only replace the memory of it.
Fault IV: random crashes
such failures are generally deserving to the use of several another piece memories, due to the memories of alter speeds to generate a period inconsistency resulting in decease
machine, which can reduce the memory speed in the CMOS settings to be addressed, only the same type of memory. Another potentiality is that memory is not compatible with the motherboard, such phenomenon is generally infrequent, the other is also possible that contact with the motherboard memory computer promiscuous crashes caused by bad. 01
common Fault 5: After the memory to increase system resources, but reduces
such phenomena are generally not compatible with the memory because the motherboard cause, common in high-frequency memory memory fknow next to nothing ofme does not support this frequency of memory on the motherboard, when such a failure you can try the COMS memory speed will be set at a low point try.
Common Fault 6: Run some of the software often hints
memory of this phenomenon is generally due to insufficient free space on the system disk, you can delete some needless files, leaving some space that is can be generally maintained at
300M or so.
Fault Seven: Install Windows to boot from the hard drive to detect disk space, memory
prompted such failures are generally due to the user in the config.sys file added emm386.exe file, at the peak of it can block out the problem. CD-ROM drive is
microcomputer hardware accessories in 1 of the shortest life. In truth, many scrap the steer still has many of value, a little livelihood at all times what you can. This often do not have whichever progressive learning of the radio, do not need everything too complicated mend tools and matters. As long for you carefully inspect the symptoms and execute the following with reference to some troubleshooting, I trust you can restore the old drive or the old
common fault I: drive when the hard disk light always flashing work
This is an illusion, it is not. Hard disk light flashes because the same drive and hard disk connected to an IDE interface, CD-ROM drive working light also controls the outcome. Single drive element can be connected to an IDE interface.
Troubleshooting II: In the Windows environment on a CD-ROM when ROM to a certain extent. Most CD-ROM drive connected to the IDE interface is not supported
Windows 32-bit disk access, so that Windows generates an internal error and crashes. Into Windows, the check box to turn off the confirmation, and then restart Windows, in Windows no longer way the CD-ROM into the error will not.
Troubleshooting III: optical drive not properly read the disk, displayed on the screen: ?
In this case, the first observation of viruses, use antivirus software on the machine to check the virus, the virus can not find the file if the amending software to open root directory of C under the CONFIG.SYS if they put up light driver and the driver is being destroyed, and processing, txt editing software can also be used to view problems not found above two treads, removable drive maintenance.
Troubleshooting four: drive to use when prompted to read and write errors or diskless
this phenomenon for most of the disk Shihai there is no location on the drive for operation caused the failure. on the drive entire the operations will need to await for the disc light is favor the bit operation only in the DVD player when the time should too be transferred to zero and then changer, so you can dodge the above mistake.
Fault 5: During the screen when playing VCD movies pause or damage phenomenon
check the AUTOEXEC.BAT file MSCDEX.EXE afterward on, if so, they should be put
to MSCDEX.EXE SMARTDRV statement before; Party not to use high-speed CD-ROM to rush the program, to SMARTDRV.EXE / U; failure can be ruled out.
Common Fault 6: CD-ROM in the read data, read and sometimes not, and the longer the time to read the disk drive read the disk
no hardware failure is chiefly concentrated in the laser head components, and can be divided into two kinds: one is caused by using long laser tube of the old
; the other is the photoelectric surface of the laser lens is sordid or sordid and the displacement of distortion, so the adjustment of laser power, the need for photocell and laser tube lens washing.
photocell and focusing lens cleaning method: Disconnect the laser head assembly, a flat cable, memorize that way, open the laser head group pieces. Then head to see the jacket covered with laser focusing lens, remove the jacket will find that focusing lens consists of 4 slender copper wire connected to the converge, tracing the roll, the optical tube assembly is installed in the bottom of the lens holes in the. with a fine wire mantled in cotton napkin dipped a small amount of distilled water (not optical tube with an alcohol wipe and focus lens surface), and to see whether the level of the lens of the laser tube is suspended, it shall be adjusted suitably. Thus, the cleaning is completed.
the laser head and power in the side of the laser head gathering has a cross like a small screw potentiometer. with color memoranda under its initial situation, generally the first clockwise 5 ° ~ 10 °, installed No further counterclockwise rotation test machine 5 ° ~ 10 °, until it can successfully peruse the disk. care have to not rotate too much, so as not to burn too much power and optical tube.
Fault Seven: boot drive not detected or test failure
This may be due drive data cable connector is loose, damaged or the hard disk drive data cable jumper settings error caused encountered this problem when
waiting, we should first check the CD-ROM data cable connector is lax, if found not plugged in, it will be re-inserted, seated and if this still does not solve the problem, then we got a new data can be put on line to attempt this time if the fault still exists, we need to check the CD-ROM jumper settings, if there is an error, change it to.
mouse
mouse failure analysis and maintenance is relatively simple, most of the fault for the interface or key contacts bad, broken, dirty mechanical positioning system. a few failures of internal components or circuit Weld mouse, which is mainly found in certain low-quality products, especially in the light-emitting diode, IC circuit damage to the majority.
a common fault: can not find the mouse
1. mouse completely damaged and need replacement mouse.
2. mouse connected to the host serial port or PS / 2 mouth exposed, carefully pick a good line, re- can start.
3. motherboard serial or PS / 2 ports from getting damaged, this situation is rare, if this is the case, had to replace a motherboard or a reg code port on the multi-purpose card.
4 . mouse line is bad, this is the most common. bad points more in the mouse inside the wire and circuit board connections. failure is not just another PS / 2 joints, general maintenance it is not difficult, usually due to relatively short lines, or compare the mouse lines are messy and lead to pull hard because the solution is to open the mouse, then use a soldering iron to solder weld. there is a situation that is bad inside the mouse cable is due to long hours result caused by aging, this failure is often difficult to find, replace the mouse is the fastest solution.
Troubleshooting II: the mouse to display, but can not move the mouse flexibility
ebb mouse pointer not as peremptory, but slow, inaccurate positioning, or simply can not be moved. This is mainly because of the mechanical positioning of the mouse scrolling axis in the accumulation of extravagant filth and lead to transmission failure, resulting in rolling not flexible. maintenance of the internal focus on the mouse X and Y axis on the transmission mechanism. The solution is to open the plastic pellet locking plate, remove the mouse pellet to roll, with a clean cloth dipped in mild cleaner on plastic Ball cleaning, shaft friction can be cleaned using alcohol, preferably a few drops in the axis at the sewing machine oil, but it must be cautious, do not stream to the friction surface and the suture on the grid encoder would be cleared of all dirt, the flexibility to restore the mouse as ever.
Troubleshooting III: the mouse button failure
1. the mouse button without activity, this may be because the mouse buttons and board too distant away from the micro-switch or click on the alternate behind a period of depressed competence to use the bounce. open the mouse, the mouse buttons underneath the glue a moderate thickness of plastic membrane, the thickness is determined according to actual needs, can be prone of afterward use.
2. mouse button can not be normal up, this may be because when the key switch in the bottom of the bowl-shaped micro-fracture caused by exposure to film, especially the long-term use of plastic is easily broken reed, if a three-button mouse, you can a key that will remove the navel to the emergency, if the original is a good quality brand-name mouse, you can solder, the open mini switch, carefully clean the contacts, some of the grease, the bottles can be used.
Keyboard
keyboard use, failure of performance of a variety of forms, the causes of many of there wrong failure, mechanical failure with their own keys, as well as logic circuit fault, Weld, false soldering, sealing off the hole oxidation and metal failure. maintenance of symptoms according to different inquiry to determine, find out the cause of the malfunction, make the appropriate repairs.
a common failure: some keys on the keyboard, such as space key, enter key does not work, sometimes, adjustment shall be entered many times before - one or two characters, and some
key, such as the up cursor key is pressed longer, continuously moving the cursor on the screen, then the keyboard Other characters can not enter, need to press in order to bounce
.
this failure to the keyboard new keyboard, the keyboard card key failure is also sometimes occur. a keyboard key to card phenomenon caused by the following two reasons: one reason is that the Caps box below column position offset, making the keycap is pressed and the key body shell stuck the card can not bounce caused by key, for this reason occurred in or near the new keyboard on the keyboard. Another reason is the key long-term use, the spring-elasticity becomes poor, shrapnel and the press wand friction larger, can not make key bounce caused by card key, because this occurred in long-term use of the keyboard when the keyboard key to card failure occurs, can be dispensed under the keycap, and then pressing the press lever. In terms of pole elastic not up or fatigue, is caused by the second, otherwise the first cause. If the body shell as keycap stuck with the key causes of put a gasket between the body, some of the gasket can be slightly harder plastic (such as discarded floppy disk jacket) made of, its size is equal to or slightly larger than the key body size, and in the open position by a rod through the ammonium can free rod through the square hole, it sets in at pole, plug in the keycap; keycap with this gasket to prevent stuck with the key body can repair the fault button; if the spring because of fatigue, the resistance becomes large shrapnel card key causes failure, then the body can be special key to open, a little traction return spring to restore bounce; remove shrapnel will resume key body by removing shrapnel, to reduce the resistance by rod bounce, so that the failure to get key the resumption.
Troubleshooting II: some characters can not enter.
if necessary one key character can not enter, it may be the key failure or joints Weld. inspection, according to the method narrated above to open key
plate, contacts with a multimeter measuring the resistance silhouette of the off state if the key does not always turn on when pressed, then button reed labor or bad, in need of repair or replacement; if the key press off when the contacts under normal, indicating that may be due to cold solder mutual, sealing off holes or gold dust due to oxidation, can be measured by the printing line, paragraph by paragraph, identify failure to re-weld; Ruoyin metal hole oxidation and failure can be clean oxide membrane, and then re-weld; if completely off the metal hole caused by open circuit, and the welding wire can be connected.
Troubleshooting III: If more than one not in the same col, not in the same line keys can not enter.
may be elsewhere in the column line or row line circuit, or logic doors may have problems. 100MHz when used to detect high-frequency oscilloscope to find the device Weld failure point, and then repair.
Fault IV: keyboard input and screen display of the character is inconsistent.
such failure may be due to short circuit the circuit board caused by the phenomenon, its performance is based on The key is shown as the same as the other symbols, this time can be weighed multimeter or oscilloscope to determine the point of failure after repair.
Common Fault 5: Press a button produces a string of multiple characters, or button when the characters bounce.
This phenomenon is caused by the logic circuit fault. first select a column of characters, if the Enter key a row without a column, may produce the phenomenon of a number of other characters ; if the one with the Enter key, will have a bounce and can not be the last character of the phenomenon into the system, check with an oscilloscope logic circuit chip, the chip to find fault with the model after replacing the new chips, troubleshooting.
Modem
Troubleshooting a: 56K Modem is not up to the 56K. This problem can be from the following considerations:
1. the actual 56Kmodem can only reach maximum speed of 53K know next to nothing of, to consider the various effects, 56Kmodem speed generally between 45-53K.
2. Modem tel line to a large amplitude affect the displacement rate, if poor quality tel lines, line voltage instability, 56K Modem
on the last of less than 56K; Another use of the Internet extension will also affect Internet speed.
3. not installed the correct driver.
4. and ISP with different protocols, only your Modem and your ISP concert is the same, Modem will to 56K criterion.
eliminate the above reasons, your 56K Modem is still much faster than 53K, this is your Modem hardware problems can be considered a replacement or repair
.
common Fault 2: Modem often dropped, resulting in dropped calls there may be several reasons:
1. poor quality tel line;
2. If the data final ready (DTR) signal is invalid duration Over Modem default settings, it will cause dropped;
3. If your call has a open;
4. In addition, Modem their quality and compatibility problems among different Modem Modem is caused by a mutual cause of dripped phones.
Troubleshooting III: Modem no dial tone
When the Internet in the dead of night, in mandate to make the turntable tone does not influence the others slumber, through the fitting AT command to change: You can use the ATM0 set Modem no dial tone, and ATM1 set Modem from dial-up linkage for a turntable tone For volume culling you can change the following directions, ATL0 (low volume), ATL1 (low volume), ATL2 (in volume), ATL3 (lofty volume).
Troubleshooting four: do not fax speeds up to to 14400
Modem maximum fax rate is 14400, and fax only when the rate of 9600. This is because most of the fax machine to mail and receive rates are
is 9600, and only use the rate of 14400 or 33600 fax, Modem fax speed will reach 14400.
Common Fault 5: Modem can not dial or connect
If not properly installed on your Modem, communication will not work. The following lists the authentication process with the Windows Communication Modem installed an incompatible driver files, may lead to the COM port and Modem not working properly, so you should first check whether the correct Windows98 loaded file.
1 test existing communication file
(1) the System directory COMM.DRV and SERIAL.VXD file with Windows95 floppy disk or CD-ROM in the original file to contrast, check
check the file size and date are the same.
(2) to validation the System.ini file in the retinue lines: [boot] Comm.drv = Comm.drv [386enh] device =* vcd
(3) In the Run ini is also not related with
* VCD files These files are built in VMM32.VXD in.
2.
test your modem configuration in the , click the options, set the maximum baud modem advocate, and click .
4.
check the correctness of the port in the br> listed ports are correct. If not, please select the correct port, and then click > In the The port's current resource settings, see your modem manual to find the correct settings in the modem conflicts with other devices, click the COM3 ports use the same kind of
IRQ, and in most computers can not use either. COM2 and COM4 have the same problem, if feasible, change the COM3 and
COM4 port IRQ settings, so that they no longer clash In addition, there are also some display cards and COM4 port residence conflict, if conflict found, amuse use other ports, or replace your graphics adapter.
6.
test port settings in the and calibration.
7.
modem baud rate test in the Then the wag
special rate is set to the correct rate.
Note: If you call the main system in the original set baud rate can not communicate, then sometimes lower baud rate may solve the problem.
printer
in the office, the inkjet printer is to use it in a more general kind of equipment the use of inkjet printers, maintenance, unsuitable operation and other elements often will be some failures, how to resolve user concerns. Here we they put their daily work and management of common faults amounted up, we ambition to help.
a common fault: typography ink scanty, indistinct handwriting processing, most of the fault is due to long outstanding printer use or other reasons,
XB 2011, resulting in the ink delivery system disorders or nozzle clogging.
exclusion: If nozzle clogging was not very mighty, then the printer directly to perform the cleaning operation can be, if I were you after continual washing achieve, you can win the cartridge (one for non-printer cartridge nozzle, the nozzle needs to win, but need to carefully), put the nozzle in warm water soak for a while, attention must not be part of the circuit board is also inundated in water, or lead to ruinous consequences, dyed with absorbent paper to take away the water droplets, and then bathed several times mounted on the nozzle on it.
Common Fault 2: Replace the print cartridge, printer in the shoe panel First, there may be not cartridge installed, the other may be in the off state to conquer on their own age cartridge, insert a current cartridge, for to replace the print cartridge, printer ink will charge the ink delivery system, and this process in the off state ambition no be skillful to make the printer can not find the re-install the cartridge. In addition, some printer ink capacity of the measurement is to use the printer's interior electronic counter to calculate (especially in the use of color ink statistically), when the counter reaches a definite value, the printer ink is accustomed to decide, while in the process of replacement cartridges, the printer ambition behaviour its internal electronic counter reset, thus confirming the installation of a fashionable cartridge.
Solution: Turn on the power, the print head moves to the ink cartridge replacement position. the cartridge is installed, get the printer to charge the ink, ink charging process is complete, troubleshooting.
Troubleshooting III: soft nozzle block header processing
soft plug plug manner is due to manifold causes on the viscosity of the ink in the nozzle due to break bigger fault. general use original ink cartridges can be revived after repeated washing, but This method is too wasteful of ink. The easiest access is to use your hands vacant cartridges for nozzle cleaning. with an vacant cartridge cleaning before it gets inside the cartridge with a needle to extract the residual ink as possible, the cleaner the better, then add clean solution (aftermarket bargain). filling cleaning liquid should be in a clean environment, will add a good cleaning liquid cartridge according to the normal operation of the printer machine, printer cleaning by key continually be cleaning. the use of cartridges remaining in the ink and cleaning fluid mingled light color print test, the normal good ink cartridges can be replaced after use.
Troubleshooting four: Clean the pump nozzle printer troubleshooting
printer cleaning something wrong with the pump nozzle is more, and it is one of the main factors caused by the plug. printer on the print head nozzle cleaning pumps play a decisive role in the conservation. head back to the car bit, to clean the pump by the languid exhaust nozzle of the nozzle knob, for nozzle seal protection in the printer or install a new cartridge nozzles are disconnected, the suction pump to the bottom of the machine through its exhaust nozzle, the higher the better accuracy of the work of the mouth, but in actual use, it performance and air tightness due time, the dust and ink residues in the mouth of the condensate increases. If the user does not observe or clean it regularly, it will keep you out of some of the print head failure.
conservation of this part of the method: Remove the printer cover away car, using a needle wash them inhaling pure water, of special note, embedded within the pores of the mouth to fully clean the gasket in this to be particularly attentive the user to clean this component, do not use ethanol or methanol to clean them, this will cause this component dissolved in the mosaic of the porous gasket deformation. Also to say is that inkjet printers as far as possible away from heat and dusty work environment, only a good working environment to ensure long-term regular use of the machine.
Common Fault 5: normal and printing ink line detection accuracy was significantly aggravate treatment in the use of inkjet printers
will be the use of frequency and timing of the extension of the gradual deterioration of printing accuracy. ink-jet printer head is also a life. general use from the beginning of a new nozzle to the end of life, the more smoothly if you could not see any fault, then, is 20 -40 cartridges sum of life, if your printer has been used for a long time, now print less exactly, you can use the method of replacement ink cartridges to try, if for a few cartridges, print output results are the same, then This printer's nozzle you will be replaced if there is a change after the replacement ink cartridges, indicating the possible use of the cartridge you have poor quality non-original ink.
If the printer is new, the results can not print that your satisfaction, often printed line is not clear, skewed text graphics, text, graphics outside the boundaries blurred, print out the ink control synchronization accuracy, this means you may purchase a counterfeit ink cartridges or use non-original productions, it should be now replacement.
Common Fault 6: encounter dislocation trolley treatment
inkjet printer trolley trace by two sets of bronze powder alloy round steel shaft with a combination of precision slide completed, however walking there is a small car designed and installed to accessory the shaft lubricant fuel Felt, but the environment we live in the dust everywhere, over time, due to atmosphere oxidation, dust damage to the surface of the shaft lubrication Oil aging failure, then if it continues to use the printer, the shaft will be increased friction with the bronze sleeve dislocation caused by the car to walk up to the collision caused the front can not be used.
solution is: if there This failure should immediately turn off the printer, will not hand back the car back into place parking spaces. to find a small chip of sponge or felt, sewing machine oil on the oil-dipped bread, forceps rub back and forth on the spindle, rather the spindle is removed, washed and oiled, so that the best results.
meet another car because of damage caused by the device. printer automobile parking spaces on the altitude of a photoelectric sensor, which is to printer print car motherboard provides an important component of the reset signal. If this component is too large or damaged due to dust, the printer will not find a car back to digital signals cross the front, and unusable, the general failure of this device need to be replaced.
display
a monitor for a long time, and a variety of small problems would follow. experts believe that to solve these little problems is actually very simple, with a pair of eyes can see where the failures.
a common fault: the computer screen of just machines quake badly, and sometimes even the icons and text is also not clear, but after twelve minutes and then will return to normal.
this phenomenon occurred in watery climate, the humidity inside the monitor's sake. To solve this problem, the use of food packaging in the damp dirt with cotton string together, then open the display cover, will hang in the damp sand tube tubes tail close to the seat tube near the cervix so that even in wet weather, will not appear above the , darkness. to wait several minutes later to appear on the screen.
seat tube leakage is due to be replace the tube socket. open the back cover to see the end of the tube a small circuit board, tube socket on the solder on the circuit board
Carefully unplug this circuit board, and then welded pipe under the seat, to the electronics store to buy back a seat the same tube, seat tube and then welded back to the board. Then Do not rush to the board and putting it back to first find a small piece of sandpaper, very carefully after the end of the tube protruding pin erase clean with sandpaper, especially pay attention to pin on the oxide layer, if necessary lustered clean and will soon relapse. the board back attach and you're done.
Troubleshooting III: there is always staying on the monitor screen clutter interference or lines, and the speaker also has a nasty noise.
This phenomenon is mostly due to poor power supply interference if too idle to get comprised, you can replace a new power supply if there are enough hands to
power can also try their own replacement power supply within the filter capacitor, which often can be effective; if the result is less manifest, can be replaced
switch to.
Common Fault 4: display the video.
this problem is more caused by graphics card if the alteration is the new graphics card, the card may be of poor quality or conflicting, then there is not installed correctly driver if the old card and added memory, then there may be new graphics and additional to the aboriginal prototype parameters alter due to memories.
Common Fault 5: display a black screen.
card if it is damaged or broken monitors and other causes no signal to monitor, the monitor light is blinking does not receive a prompt signal. If the resolution is set too high, more than the maximum display resolution will appear black, caustic dispose of the display, but now the display has a protective function, when the resolution exceeds the set value is automatically protected. In addition, hardware conflicts can cause a black screen.
display jitter causes
monitor activate rate is set too low
when the monitor refresh rate is set below 75Hz, the screen will appear often shake, glow, appropriate to addition the refresh rate, such as set above 85Hz, the screen jitter phenomenon is generally not occur again.
power transformer and chassis from the monitor too close to
power transformer will result in Jiaoda electromagnetic interference, resulting in screen jitter. the power transformer away from the chassis and display areas, the problem can be solved.
Liezhi aging power supply or power supply has many Zapai
computer power supply used components work, materials are very poor, could easily lead to poor or computer circuit power supply capacity can not keep up, when the system is busy, the display screen will emerge, especially the phenomenon of jitter. computer's power supply at the starting of aging , are probable to cause the same problem.
get away from the monitor speakers placed too close to the magnetic field effect
speakers will interfere with the normal operation of the monitor, the monitor screen jitter and produce attractive interference such as cross color .
virus trouble
some computer viruses will disrupt the display, such as: the character upside down, shake the screen, graphics, flip display. everywhere online screen jitter script is enough to keep you in After the first big move as a bull.
card bad
re-inserted card, the accessible fault exclusion.
WIN95/98 system write cache causing
as part of this reason, in the Control Panel - System - Performance - File System - Troubleshooting disable all drive write-caching, allowing the problem to be solved.
power afford percolate capacitor damage
open the case, if you see a power supply filter capacitor (the biggest kid in the circuit board capacitor) at the top of muster, then it shows bad capacitor, the screen jitter caused by power failure. changed capacitor, the problems can be solved.
burner
Troubleshooting 1: Install the burner does not start after computer
First off the computer power supply, open the case cover check IDE cable is entirely inserted, and to assure that PIN-1 position of the pin is connected correctly and if the recorder and other IDE devices sharing an IDE cable, the need to assure that two devices can not be set to can be a Set ample environmental conditions such as burning, but can not burn the disc to be tested if there are problems and burner laser power and disc read-write head matches, etc. In view of this, that shows that between the recorder and blank disc compatibility is not very good,
PULSERA CAMUFLAJE CON LOGO XB, the following two methods can be used to re-try it:
1. reduce the burner write speed, 2X suggested the following;
2. replace variant mark of empty discs because burning actions. there's dissimilar reason why this phenomenon is the power of the laser heads diminution phenomena, if you use the same brand of record recording, the first time were customary, then it is power attenuation may be narrated to the write pate can be sent to the vendor maintenance.
Troubleshooting III: Unable to duplicate the game CD
some large-scale advertisement software or game software, in the making process, CD-ROM disc to do to protect, so the process of making CD-ROM replication, there will not be copied, resulting in the burning process the error occurred, or not work after copying to occur.
Common Fault 4: burn CD music not normally play
not all audio devices are functioning properly read CD-R disc, and most CD players can not properly read the contents of the CD-RW disc, so it is best not to burner to burn a CD with music will also need to note that burn music CD, CD-DA must meet the file format.
Troubleshooting five: the process of CD burning software to flame, sometimes then transmitted through the IDE interface to the recorder's cache (BufferMemory), the final author to cache file in
BufferMemory in recording message onto CD-R or CD-RW disc, these deeds must be continuous, must not be interrupted, if any one part of a problem, will not normally cause burner to write data, and the emergence of a buffer underrun error, then the disc scrapped. The solution is, before the burning need to close some of the memory-resident programs, such as turn off CD auto insert notification, turn off your antivirus software, Window Task Manager and Task Scheduler and screen saver, and so on.
Common Fault 6: CD burning process, often appear burn burn failure
improve the success rate of a simple need to maintain the system surroundings, ie turn off the backdrop dweller agenda, it is best to arrange for the recording system, a devoted hard drive, specifically associated to software installation and burning in the burning process, ahead the data is best stored in the hard drive, made into
Repair computers, - yourself .
