Re: 6600GT black screen / Restart
I had 2 9800pros that died whilst idling over night, I didnt believe it was the cards as I would expect them to have died whilst under load, as stated earlier, welcome to PCs! I would try a board and if it still blacks out "take it back and say you bought it for someone for xmas and they've already got it or something like that" then return your card, if it works keep the board, have you tried a mainboard bios flash?
