I need some help. My screen will get pink and blue and other colored blocks all over it, usually the upper two thirds of the screen. Over a couple seconds it gets worse, then the screen turns blue or black. It seems to happen the most when I'm browsing the web with firefox. That seems to agitate it more. Also the drivers crash and restart nearly every time I try to play a game. The video card doesn't have much mileage and I just updated the drivers... but that seems to have made it worse! Stevil said it could also be a bad power supply, and that makes sense cause I've had it for much longer than the video card. He linked me to a download for TechPowerUp GPU-Z, and I've been watching it for power fluctuations but I haven't seen anything beyond jumps from 1.0 to 1.1. Are there software tests I can run to test the power supply and video card? Could it be drivers? Or maybe the motherboard? Possibly a short somewhere? I'd like to know how to test for these things, where to look, and if there are software testing programs anyone can recommend that are good?
