Im running a EPOX EP-8RDA+ Motherboard with a AMD ATHLON 2500+ (BARTON CORE), ATI ALL-IN-WONDER 8500 (128 MB MODEL) with 512 MB Ram (Crucial) PC2700 MEMORY, And NFORCE 2 SOUND (Built onto Motherboard).

I am getting a blue screen with ever game I go to play... I solved the video driver problems I was have but now it is the file NVAPU.DLL the the blue screen list as the problem... But it only occurs with games I can run non-acelerated games or go online as much as I want but when I try to play a real game like Return To Castle Wolfenstein (RTCW) Or Spider-Man The Movie I get a blue screen or the game just crashes and exits, Sometimes I get lucky and there is no blue screen.

Anyone know the causes of this or have a solution?

I have already tried various aperture sizes, using DirectX's Refresh rate overrides, New drivers, patches, and Upgrading to DirectX 9.0. I have also tried just about ever possible setting as far as ATI's Catalyst drivers allow.
