I have a Geforce FX 5600 256mb, don't know the manufacturer. The fan on the vid card doesn't spin at all while the machine is on, and pretty much crashes whenever i try to do anything 3d(overheats). The fan itself as in the blades is completely intact(but it won't spin), but I think I might have broken some connection when I got into my case the other day with some Q-tips trying to get rid of dust. That will teach me to scrimp on compressed air cans. Anyways, anyone know how I can fix this problem, or do I need a new video card?
