Motherboard or Cpu problem?

post #1 of 14
Thread Starter 
So today I moved my computer back into my room. I set it all up, and turn it on. I hear a little pop, and the computer turns off. The computer then reboots. I unplug it quickly and open up the case. I can smell a little burned smell coming from the gpu area. I take out the gpu and test it in another computer. It works fine. So then I try the gpu in a different slot on the motherboard. N luck. So I then take it out of the case and set everything up on my desk. When I turn the computer on, it would stay on for about six seconds, but right when it was about to do the post beep, it would shut off. Then it would automaticly turn back on again, and do the exact same thing. I tried all of the different slots for the ram on the motherboard, and tried each stick at a time, but it does the same thing. I took out the cpu and looked at the socket, and I didn't see any bent pins. I felt the cpu, and it wasn't warm at all, and then I felt the nb/sb, and it wasn't warm at all either. All of the lights n the motherboard go on, but it won't work. I also tried booting with a different psu, but still no luck. Please help Thanks!

Maybe a surge or something similar? Inspect your VRMs, are you *sure* it came from near the gpu?

I hate to be stupid, but where are the Vrm's? I am pretty darn sure it came frm near the gpu area. I smelled near my sound card, near my cou, near my ram, and near my pus, but I didn't smell anything.

Why didn't I think of that?

It's probably the psu. That explains the smell being near the graphics card.

I think the smell can be sensed anywhere in the case so it can be anything

It sounds like the motherboard if the GPU works in another system, and swapping the PSU didn't help.

If you can, try different RAM or only one module. The chance of it being the CPU is likely slim. Remove the sound card when troubleshooting.

It sounds like some sort of power related issue took out something on the board.

If you can, try the PSU in another system to confirm it's good as well. Both could be a potential cause.

I have already tried two different psu's that I know are working, so it can't be that.
