So I just reformated my hard drive. It's perfectly clean. I have one AGP card, updated drivers, etc. All of a sudden (as in, the day I formatted) I would get these spikes in CPU usage like crazy. Everything would be fine, then all of a sudden things would SLOOOOWWW down tremendously. I checked task manager, and the CPU was at 100% usage, with taskmgr.exe being the culprit! I've scanned for viruses using everything I have (Antivir, hijackthis, adaware, syware remover) and found nothing (again, clean install). What should I do?

Check the event viewer. I would suspect a faulty video driver, not taskmgr.

yeah i thought so too, so i updated the video card drivers to (from drivers i had saved pre-format) and it still happens!

maybe it's my onboard vga? I have an S3 onboard vga adapter that I've disabled in the BIOS.

The EventVwr just lists a bunch of application hangs (whatever happens to be running... itunes, firefox, etc).

I restarted the machine with just my onbaord vga running, and the problem went away. However when I reverted to my AGP Geforce 6600, it came right back. I reset config data in bios, reset the bios, re-installed onboard and agp drivers (not in that order, of course). Basically I re-installed EVERYTHING. Yet the moment i do anything like play an avi or a video game (even a 1 mb process) everything still slows way down, and the taskmanager shows taskmgr.exe using up 60-100 percent of the CPU.
Damn.

Yep! Seems to be the video driver. Try an older driver for that card.

Well, I formatted the drive. Everything is fine now... but I still get some random errors (probably a bad memory stick).
But that damn problem went away.
So for those of you stumbling, just format your hard drive and re-install all your drivers, onboard and AGP/PCI.
