Well i just installed the latest Nvidia driver
and it still froze on me in Call of Duty MW2. The colours went crazy and the sound stuffed up, had to reboot.
I decided to make the fan run at 100% and i didn't even last 10minutes into a game and the PC just blacked out and rebooted itself.
MSI Afterburn says this:
Display device : GeForce 8800 GT on G92 GPU
Display driver : 126.96.36.19945, ForceWare 197.45

This is really fustrating lol, any help would be much appreciated
