It runs normal when I first turn my computer on, and then it starts and stops again. again. It basically runs normal, then stops. Then goes again... and stops. Over and over. I actually feel some sort of resistance when I spin it with my finger, and it doesn't spin how It did when I first got it. Also before the starting-and-stopping thing happened, it also started getting hotter. I think the fan has something slowing it down on the inside. Maybe it needs to be greased? I can't know because I'm not sure how I open the fan up and fix it. It seems when I set the fan speed down to around 60 it stops. But it's also still slow... so It doesn't properly cool my graphics card. If anyone can help I'd be grateful. I don't feel like ordering a new graphics card.
