computer freezing plz help

[element771]

just put together a new rig...at first no problems... now the damn thing keeps freezing while im playing GTA3 and splinter cell. I tried installing new drivers and then I tried lowering the video acceleration. The error I got one time said that the video driver I had caused instability. Anyone got a solution? I dont think it is overheating. Thanks a lot for any help.

I have:
P4 2.68 Ghz
Radeon 9700 pro
1024 Samsung 400 Mhz RAM
MSI SiS 655-Max Board

If it ain't broke, take it apart & see why not!
