Hi there, what I mean is the fan on my graphic card goes loud and fast and it never used to do that. My reset button doesn't do anything. The moly way I can stop it is by holding down that main switch for a few seconds to shut the computer off. The monitor won't come on because it does not recognise any signal from the graphic card. I have no idea what is causing the problem.
Try removing one GPU.....if it fixes it than good. If it still is messed up, remove it and add the other gpu..so put each one in ALONE and see if that fixes it. Maybe it just reached its end because that is an old GPU.
