I made a post on another part of the forum about my computer shutting down on its own. One thing lead to another and I eventually figured out that my power supply isn't failing and my Cores are not overheating. It appears to be my graphics card. The fan is not spinning nearly fast enough and very weakly. The fan cooling my processors would hurt my finger if I touched it but the graphics card fan just stops. The heat sink under the fan is really hot. I almost burned myself. Is there any way I could manually set the fan to go faster before the card overheats and turns my computer off? I currently use an ATI Radeon HD 4800.
