I am using a 6600GT and have been seeing purple and green shapes quickly, randomly flashing around the screen. This happens shortly after I start to play a game like WoW or even Civilization IV. The shapes appear more and more until the whole screen is a mess of them. I am running the card stock, put into a Dell from around 2004 (4200 I think). The only way I can prevent them or get them to stop is if I leave the case open and put a room fan pointing at the case on high speed... medium and low don't cut it. I assume heat is causing the problem, but I'm not sure why... the card has only started behaving like this since playing the two games I mentioned. I've played Neverwinter Nights and Elder Scrolls: Morrowind... no problems that I recall. Would an updated driver possibly help? Is my card malfunctioning? Is it possibly not getting enough power (there's no power connector for the card, but didn't know if power could still be an issue via the mb?)
Thanks for any info!
