Hi, I just finished building a new PC for my brother and we gave it a test run. We installed UT3 (The Game)to give our new beast a spin. Everything ran fine for a few hours but suddenly the whole thing just shutdown. To save time I won't go into all of the specs details. I have unplugged everything inside the CPU tower and attached just the PSU to the MOBO but still it won't start when I press the power button. All I see is the power LED for a few seconds on the CPU tower before the LED dies completely.

Is my brand new 550W Crosair PSU dead or is my brand new Gigabyte P35-D series MOBO dead? How can I check to see what has gone wrong without having to take it to a tech nerd.

Thanks in advance.

That's pretty much everything important. I've used the same heatsink+fan combo which came with the Quad Core. Although I removed the thermal paste which was already on it and applied Arctic Silver for better efficiency.

One important thing is that I've done a test built of these specs while I was in Canada, where voltage was 110-120 and everything ran fine. I am now in Pakistan, where voltage is 220-240, and upon powering up the test build everything also ran fine as the Corsair PSU automatically converted from 110 to 240 (one of the features it has due to which I bought it in the first place).
Like I said everything ran fine for a few hours until it completely died. Now when I press the power button, the power LED comes on for a second or two and then just dies. Nothing powers up!

when i changed cases of my last computer mine did the same found out it was becuase the mother board was touching the case, just check you yours isn't and that you haven't left and screws lying around.

Thanks for your reply. The thing is I have tried taking out the motherboard, placing it on a wooden box and then trying to boot it but still no luck. There are no loose screws or anything laying on the motherboard or around it. So any other suggestions?

Just for the sake of argument, what if there was a small screw which had fallen onto the motherboard and I booted it up and it short circuited due to that. Has that destroyed the motherboard or the PSU?

Have you tried borrowing a PSU from a friend to help rule it out?

If it comes down to it I would RMA both and get new ones.

Sorry for re-opening this thread after such a long time. I've been busy with exams. But now that I've cleared them I would like to build up my rig ;)

So as you guys had suggested, I took my rig to a friends house. Although I couldn't test his PSU on my MOBO as it was not compatible but I did test my PSU on his MOBO.

Surprisingly enough, his MOBO did boot up and ran just fine. So does that mean that my MOBO is indeed dead? If so then how could that be considering if the voltage difference were to be the case shouldn't the PSU be the one to be fried?

Secondly could it be that maybe another part of my built is malfunctioning i.e RAM, Video Card etc. without which the MOBO won't boot up so I can't test to see if that is the case by removing them from the MOBO.

Aggggh, I'm frustrated and don't know what to do. I don't want to spend money on a new MOBO because MOBO prices in Pakistan are through the roof and I know I won't find exactly what I need.

Your input with be greatly appreciated as you guys have never let me down before!
