The problem started about three weeks ago. After about 5-15 minutes after starting any new-ish game, my computer would lock up with a screen that looks like this:

The colours would vary every time, as would the exact time of the crash. The strangest part was that the crash would only happen once a day. After it crashed once, it would only happen again after a long period of time. Unfortunately, the problem got worse and worse. Now I can't even start windows without a crash. Disabling the card in the device manager seems to fix the problem, which is why I'm certain that it's a problem with my graphics card. Sometimes I'd still be able to start my computer without the card dying, but it's been rare.
I'd just like to know if my video card can be salvaged, I'd really hate to have to replace it.
I'm running off Vista. The card is a GeForce GTX 280, and the motherboard is an ASUS P5Q PRO. I've owned my computer for almost a year without any major problems.
