I think one of my 8800GT is going bad. Its the one that I had problems with when I first got it (fan sticker got loose and caught on the fan making it overheat). I gave this one to my brother because I wouldn't have to mess with the fan speed. However, today when he turned his computer on, one of the monitor had a blue tint. After a couple of trial and error, I found out it was the second DVI port. That means the card is going bad right? Or is it just that port?
