I have had this problem for a long time and now I decided to ask here. Please read the whole text before answering. Thanks in advance.
Ok so let's start. First time this happened like half year ago when I was playing Battlefield Bad Company 2. I was normallly ingame and no fps drops or lags at all. Then suddenly my screen froze and came full of different colored pixels. The sounds get also crappy and messy. Then I got a black screen and the only thing I can do is to go Task Manager and stop Battlefield Bad Company 2.
This has happened also while playing other games like Combat Arms and Battlefield 3. But usually when running harder games like the newest Battlefield series, not that much with Combat Arms.
I sent the whole PC to warrantyservice and they found that graphic card was broken/dead and they replaced the graphic card. First it seemed to work fine, but then I started to crash again. This time I didn't have the warranty anymore.
I have also installed newest drivers and tried older drivers.
I found many similar topics in the internet but it seems that there isn't any solution Since the card is replaced the issue can't be the graphic card.
Looks like a bad design or temperature issue like amuffin said, I think you should geta replacement of eVGA brand .
I won't buy a new card before being sure that it's card's fault. Because if it isn't card's fault, I just "wasted" 150-250 euros for a new card. GTX460 is great for me, at least at the moment, so I don't need a new card yet.
