Alright, first and foremost I wanted to say hello to you all! I registered here today because I'm at a complete loss. I just bought an MSI 6990 video card to replace my HD5770. I've installed it, and it runs fine for the most part, however, the temps idle are around 53c and when I play a game (dragon age 2, RIFT, etc) the video card will shut off after a bit, but the comp stays on. I have a 700 watt power supply, I beleive I have everything set up correctly but I don't know what else to do! Any help would be very much appreciated.
