Getting dropped to the desktop

[firestorm225]

I've been having a lot of troubles, but after a few formats and reinstalls I've finally gotten the system up and running, or so I thought. I'm having graphics card problems. When trying to run 3DMark, during the second car chase test I get the little "Critical Stop" sound bit and it drops me back to the desktop. Just right now, I fired up the Need For Speed 2 Demo, and again, after a few minutes, my screen got all corrupted and I got dropped back to the desktop (and the area next to the start button and taskbar looks messed up now).

I have a Geforce 4 TI 4200 and the 30.82 drivers. Any suggestions?

Here's the rest of my system:

1ghz T-Bird
384mb ram
Windows XP with SP1
430W power supply

EDIT: I ran 3Dmark again, and it dropped out at just about the same place, except I got this error:

Any ideas?

Try the new beta 40.72's. They solved some of the problems you're having at my end, too.
