3d apps crashing

[jeffa66]

ok so basically i was playing wow when my comp froze so i reset it, now everytime i try to play a 3d application it crash's everything else works normal. i have changed my nvidia drivers about 4 times to no avail. i even reformatted my comp with fresh drivers and i still have the same problem.
im using a 6600GT and a nforce 4 mobo. any idea's?

Define "crash":

• Memory access violation (Windows "send error report" box or memory address error box)
• Blue screen/auto reboot
• Hard lockup
• Soft lockup (ctrl+alt+del able to bring up task manager for you to terminate the app)

Does this occur with all games? If you have any OpenGL games (All Quakes, Wolfenstein, Doom 3) do those also freeze? Updated to latest chipset drivers?

the game will start fine then after a minute ot two the screen will start tearing and it lock up but i can alt-f4 or ctrl-alt-del out of it.

Sounds like your g/c could be on its last leg. Check the card temps to make sure it's not over heating. if overclock, back down to stock and stay there it things start to stablize.
