While playing some game a month ago my screen became all green and purple with squares everywhere it was like some terrible mspaint job. I took out my 7600 gt , after restarting multiple times and barely able to see the screen, and it fixed the problem. Is it unsual for 7600s to fry like this? I bought it used off a friend but his still works fine and its not like i played any graphic extensive games on it just call of duty 4 and doom 3 and lesser graphical intensive games. Is there anyway to tell visually if a video card is fried?
