Is my motherboard fried?

[woltej1]

i built a computer for a friend and it worked fine for a month and a half or two months now. Except for when we first built it, it would randomly reboot and get caught in a boot cycle, but i moved the ram to different slots and it seemed to fix it. Now nothing will post, and the cpu heatsink fan will make about an 1/8th revolution, then return to it's starting position, sit and partially rotate and will pulse like this. Does this mean the mobo is dead?

Sounds like it could be your PSU, do you have a spare psu that you can use to test it?

Its still under warranty, go check and get it changed.

I would make sure what part is broken before sending it away to get fixed. If it's the PSU and you send them the motherboard they will likely charge you shipping and you will still have a broken computer.

Additional info, all case fans get power, hard drive gets power, but the case light showing the hard drive is being working doesn't light up

try unplug hdd's cdrom, take out the graphics card (if you have on board),

So basicly your left with mobo cpu ram. See if it boots then

ok, so i swapped in the psu from my computer in and it booted completely, so i thought ok, his psu is shot. Then to be sure i plugged his back up and tried booting again and it booted perfectly....wtf? could've there been a loose connection or what? his computer from the start has been self healing its own problems, or is there a faulty part that decides when it wants to work?

it sounds like it was a lose connection on the PSU -> Mobo. either that or there's a problem with the PSU that is temperamental. I'd give it a week and if the problem shows back up send off the PSU.
