I recently sold my GTX 480 to a friend. He installed it and said it worked just fine, although he did not try gaming on it. Shortly after, he was hit with a power surge. It took out his PSU, and he has just recently started testing his other components.
The issue he has now is that within 5-30 seconds of logging into Windows, the display corrupts and turns into one color. He's tried different PCI-E slots, various drivers, cleaned out old drivers (AMD and Nvidia), etc. His old HD6850 does not exhibit this issue when put into the computer.
He tested his GTX 480 in another friend's computer. That guy was also running a GTX 480, so they simply swapped them out without changing drivers. Apparently the display did not crash like it did in the other machine, but they have not yet stress tested it on the machine it works in. That's their next step. However, when they did swap the original GTX 480 back in (the one already in the other friend's computer...not the one I sold), it wasn't recognized. I'm thinking this is because it's a slightly different GTX 480 and not related to the potentially problematic GTX 480.
So, it works in one computer, but not the one hit with the power surge. They have not yet stress tested it on the machine it works in, so we'll see what that reveals. Until then, however, what do you think is the root cause of the issue? I'm thinking it might NOT be the GPU, since it works OK so far in another computer. On the other hand, his old GPU does not exhibit the same crash...thoughts?
