Microsoft Office Standard 2010 Windows 7 RTM 64-bi

Hi there all,

I've set up the Windows 7 Enterprise RTM (my firm has computer software assurance) on one among our devices,Office 2010 Home And Student, twin booting with XP. The Windows 7 install is totally clean, but it has a nagging issue of mouse pointer freezing/stuttering that is driving me absolutely nuts! Basically,Microsoft Office Standard 2010, every 10-15 seconds,Office Professional Plus 2010, the mouse pointer just freezes in place for about a second. The computer itself doesn't seem to be locking up but the mouse pointer will then suddenly jump back about where it should have been if it didn't freeze. (i.e., it seems to be lagging behind responding to the mouse but catches up, it doesn't continue from where it was).

It seems like the problem is getting worse the more drivers and such that I setup,Office 2007, I was hoping once I got all my sound/video drivers in it would get better.

Does anyone have any ideas and/or performance monitoring tips? Nothing seems to be spiking in task manager. And it all works fine in XP.

System is:
Asus P5WD2 motherboard
Pentium D 940 (3.4,Windows 7 Key, dual core)
ATI Radeon HD4850 video card
Asus Xonar D2X sound card
Adaptec 29320 SCSI + Atlas 15K drive (Win XP boot drive) and Plextor SCSI CD burner
Other SATA HDs including the Win seven set up drive
Razer Copperhead mouse

Thanks for any tips
