Well i was playing WoW, then it started to get laggy, so i decided i wanted to restart the computer, but i was impatient because my teammates were waiting for me to restart, so i hold the power button on the comp till it shuts off for a quicker restart, then when i try to turn on the comp, it cuts on but the monitor doesnt get signal, i open the comp and i notice the fan turns on but then it stops working i flick it and it runs for a sec but slowly then it stops. I took out the RAM and CMOS... restarted comp.. no beeps.... im guessing motherboard fried? i even tried to reset CMOS by switching the little pins and by doing that i know that the computer isnt supposed to turn on but it did... so is my MB fried or is there something that i dont know about?

Start with the power supply. Try a known good one from a buddies computer. There allot cheaper to replace then the motherboard. If the power supply checks out I would try a different video Source (onboard, a diff card) if all that checks out then order a new MB. They fans that stop running are they case fans or CPU fans (what I am wondering is if they are speed controlled and slowdown or stop after the initial POST then speed up as necessary)?

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?
