My bad, I was replacing the thermal compound again. I thought it looked a bit smeared. So I took the entire thing apart and cleaned it all out and tried to put it back in. The problem now is that the fan won't even spin. I know the card still works cause its heating up and stuff. Anyone know how to make it work again? The fan is already plugged in and on boot up, the fan moves a little bit then comes to a stop.
The problem with the other graphics card was that the fan wasn't plugged in, that was my fault.
