please give more info.
Have you OCed it?
what is the ambient temperature?
how old is the card?
Is the driver up to date?
It isn't overclocked.
It idles at about 60C - 62C.
The card is a few years old now, I believe.
I just updated the drivers and tried playing some games again, it froze.. did the pixel screen stuff, then both monitors went black and went to standby.
I just played Fallout 3 for about eight minutes and it did it again, my GPU temp was about 68C and GPU usage was at 96%. I've done driver updates and a system restore and I still can't fix it..
