Try to use use compatiblilty mode, if you have sp2 or 3 http://support.microsoft.com/support/kb/articles/Q279/7/92.ASP just a shot anyways....

Via is truly bad with there products, and back it up with bad driver support. Being the cheap person i am, i baught the k7s5a(sis735) when I uggraded, and has been one of the most stable systems i have used, I dont feel bad for anyone buying anything with VIA chipsets. Best thing you can do is stay away from VIA chipsets all together.....

NAV CE for sure.

You put the cd in the drive, reboot, make sure your set the bios to boot off the cd. It will boot off the cd, run setup, you will get to a point to select Repair, and run the automated repair. Done and Done
