I was playing tf2 and right when I started a round, the whole level glitched out and there were fun colors and pixels and everything. I attempted to run other games on other engines, (namely: Minecraft and deus ex human revolution) and all of them seemed to have the same problem,
individual or groups of four pixels would stop working and there would generally be artifacts all over the screen. It sounds like standard Graphics card overheating, but even when it is cool, and well aerated, it still happens.
I actually just got a blue screen after a particularly bad freeze. windows starts and runs normally, and videos play fine, but occasionally firefox will even trigger it.
when I first got this card, it was actually defective and i had to send away for a new one, so it could have just broken after a while, but the warranty is easily expired now.
Any help would be greatly appreciated, if nothing can be done, i had actually planned to get a new computer with SLI so its not a big deal, I would just have to accelerate my schedule and draw from my offshore accounts.
TL/DR
Whenever I open a game or firefox my pixels glitch out, monitor says its not getting an input, and screen goes black, sometimes I can open task manager and stop the offending program before the point of no return.
TL/DR the TL/DR
My video card is fucked.
