i installed the lastest nvidia drivers and it helped, but eventually it came back. Which leads me to believe it is temp releated, even though my card is only reaching around 70-odd degree. I know the 8800's can get up to quite high temps, i was thinking of getting another card for sli, but obviously 2 cards=more heat which is going to make the problem worse.
So now i've got to try and find a way to better cool my card, without chopping holes in my case. I could try an aftermarket cooler on it, or i was also looking at one of the Antec SpotCool fans.
