Boot in safe mode and try to alter the settings there... also, did you get any messages before about the drwatson postmortem dedugger? Someone I helped through that virus had a very similar problem. Brick and Neo could be right too... I'd update the driver to your card.
I see you have Anim8or... Beginner's guide to db owner?
hehe
EDIT: Go to the website of your card's provider. If don't know what kind of card you have, click start, then run, then type in DXDIAG . Hit enter, and you should be able to find out what sort of video card you have right there. Anyway, go to the company's website and find the newest driver for your card... if it's onboard, I don't know how to help you there, shy of you going to your computer's manufacturer site
