New install problem

[Fraggr]

I have an MSI K8N SLI-Platinum, 1GB DDR RAM, A64 X2 4200+, 200GB Maxtor hard drive, and SB LIVE-24bit. I just reinstalled Windows XP and I'm getting major CPU problems.

For example, if I scroll down the page when browsing, CPU usage goes up to 50% (100% on one core), same thing if I scroll up/down on task manager, limewire, etc. When I drag a window about the screen, even slowly, it has the same effect as with mouse trails.

Also, my sound card is not being detected, even though I've installed drivers for it.

Should I just reinstall completely?

I've managed to fix the sound problem now by being a bit lucky, but I've still got the CPU problem.

(I reinstalled, reinstalled the drivers, etc again)

Edit: anyone have ANY idea why my CPU usage goes to 50% when I scroll up/down pages, and move windows about the screen?

Install the VGA drivers.
