IF IT CRASHES IT WANT TO SEND AN ERROR REPORT TO MICROSOFT. THE FILE THAT'S CRASHING IS ALWAYS THE SAME: CODUOMP.EXE.

THANKS, REMMY.

The drivers are: Nvidia Omega Drivers 1.6693 (Forceware 66.93). This is the latest version they have. Is this up to date are are they a little old?
I have tried many many driver from NVidia but I kept the same problem. Also took out the battery of my motherboard cause I lost my passwword for it...LOL. Processor is running stock speed now.
Thanks for the quick answer. In the mean time I'll google on and see if I can find answers

fixed it, it was the bios. The memory setting where messed up cause i damaged a piece of ram...lol.
i have d/led the driver and it works fine.

THANKS ALL FOR YOUR HELP!!!
