I need help trouble shooting

post #1 of 3
Thread Starter 
Wasnt sure where else to post this. My buddy has a computer that just all of a sudden "stopped working". I hit the power button and the power light comes on, but no fans spin, the psu fan doesnt spin.

I eliminated the psu as being the cause, and the power switch it self. Im thinking most likely motherboard issue. Could a bad video card cause this? Can you get a computer to post without a video card? I just want to make sure Im not missing anything, I dont want to have this guy buy more hardware for no reason.

Forgot to mention when power is connected to the video card the fans jolt once but do not spin. When I disconnect power to the video card and try to power up the machine the mother board does beep once. Like its indicating the gpu needs power.

Yes a bad video card can do that or short or dead stick of ram or dead motherboard. Also check the video card for burnt spots or burst capacitors or any circuitry damage same for mortherboard front and back.

Have you try one stick of ram at a time to see if a stick of ram went bad? If you can not get a post with either stick. turn it on with no sticks of ram and see if the board will beep and stay on. Also if he using after market hs with a back plate check to see if it grounding out on back of the motherboard. To me it sound like something might be shorting out or died.

If you get no beep at this point it would be best to take apart the computer and put the motherboard on cardboard or table and start with psu/cpu/one stick of ram and see if it will turn on and stay on.If not remove that stick and try the other stick of ram and see if it will work.If it stay on then start add parts back like gpu first untill it won't post.

Also you can use eraser to clean the gold pins or alcohol on the ram and video card.

Good luck.
