My computer is booting to a random pattern. How can I fix it?

Episode 1022 (51:44)

Paul from Santa Monica, CA

Paul's PC runs Vista and today he booted up and got nothing but a pattern on his screen. Leo says it sounds like either a bad video driver or a failing video card. Leo advises going into safe mode, reinstalling the video driver and reboot. If it comes back, then he's solved the problem. If not, then he should look into replacing the video card.
