In re-reading your posts I noticed that your just getting popped back to desktop. Grasping for straws, 3DMark is running fine but not games it could be a sound card problem. 3DMark does not use sound but games do. Have you tried running the games with the sound card removed or disabled? Is all the onboard sound, unused features, etc. disabled in the BIOS?
Edit- OOOPPPPSS! Sorry you are using 3DM03 and it does use sound.
