if it was the fan on your videocard, that most likely needs replaced. if it was your cpu fan, then thats not a good sign. if it was your case fan, its not a huge worry. if its your power supply fan, you need a new power supply for sure so replace that asap before trying anything else.
unplug all unneccesary devices so u just have your mobo, cpu, ram, video, and power supply to worry about. if it still won't post, then u have narrowed it down a bit. if u have 2 sticks of ram, take one out and try it. if that doesn't work, take that stick out and try the other one. if neither work, its probably not a ram problem.
try a different power supply like the poster above said. then try another video card. make sure you only swap out 1 thing at a time though, to identify the problem hardware. if none of these swaps work, its most likely time for a new mobo and/or cpu.
Heres another question too. Is there a light on the front of the tower, and does it turn off at the same time as when the fan stops?
