I recently purchased an EVGA GTX 260 and I've been having some problems with it.
When I was playing Starcraft II, I noticed the top left of the screen was in the bottom right, and it had some artifacts. Shortly after, it froze and I had to restart my computer. That happened twice. The third time I was playing Counter-Strike: Source and I alt-tabbed to my Firefox window, and my screen went blank. I had to restart after that as well. I also see artifacts every once in a while on the desktop.
I've removed and reinstalled the drivers three different times. What could it be?
I recently purchased a new power supply because the old one didn't have enough 6-pin connectors for my video card. Not sure if that has anything to do with it.
