In the last week my comp has been freezing at random, even when just on the internet. Finally today i played a game and it froze and when it restarted it said it was my 6800. I began to look around for some fans until it froze again...now my computer starts until it gets to where the log in screen should come up, but its just a black screen, so i can only guess its my video card getting too hot. Any reccomendations on video card fans?
