So the other day I just added a new 7950 from powercolor to my rig. I used to game using integrated graphics and had no problem just low framerates and quality. Now i can play games at high but my pc tends to crash within 5-30 minutes of gameplay. I have tried all games including Orion: Dino Horde, Battlefield 3, Dead Space 2, And Tomb Raider. I use Msi Afterburner to monitor my temps and i tend to get around 65 C when load is around 94-96.the fan speeds are 8-10% higher than celsius degrees. I doubt its my PSU because its 1000 watts and by PC&P. Another thing I have noticed is that there is a faint noise that cuts in and out through the speakers after I installed the card. Usually its a constant sound. Please Help.
