Large Performance Decrease in ATI AIW 8500DV after formatting

[tcfreestyle]

Until recently my All-in-Wonder 8500DV was working great. Games worked flawless and myu benchmarks were higher than I ever had.
I just formatted my computer to do a good "de-junk." I installed Win2k Pro and used windows update to install all of the new updates. Then I installed the lastest ATI drivers then the Audigy 2 Platinum drivers. After that I ran PCMark and the benchmarks were normal, looks good so far. Then I ran 3DMark 2001 Pro and my score was 2200. I used to be getting 8700+. Then I thought maybe it was a fluke, so I installed Unreal 2003, the game was stop and go, it was disgusting, never have I had anything but seemless gameplay, looked like it was going under 10 fps. I looked around in options and found nothing that made a difference on my performance. Everything else works great. It seems odd that I am only having a problem with the video card. Can you think of anything, ever hear of this problem before? Here are my computer specs straight from 3D Mark.

are you using OpenGL? what are your settings in 3DMark? What are your Anti-aliasing and anisotropic filtering options? what about direct3d z-buffer, 32bit color, screen resolution, etc? is v-sync on?
