Brand New Build on Death Bed!

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.
 
What are you using to cool the CPU and did you use thermal paste?
But from your second part my first thought is the mobo is shutting down to overheating or power overload to protect it self, but if you are getting no video I doubt this is what is going on. You are getting no video signal right?

And please post the hardware you used, your problem might be there. ;)

Remeber boards do die sometimes, just have to replace it.
 
Hi, thanks for the quick reply. Here are my system specs which I picked with the help of this forums members a few months ago.

Code: 
MOTHERBOARD = Gigabyte GA-P35-DS3R

PROCESSOR = Intel Core 2 Quad Q6600 Quad Core

http://www.directcanada.com/products/?sku=12200BD3212

GRAPHIC CARD = Galaxy GeForce 8800GT

http://www.directcanada.com/products/?sku=24630BD6770

RAM = G.SKILL 4GB / 2 Sticks

PSU = Corsair VX550W 550W

HARD DRIVE = Western Digital 320GB SATA

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!
 
How do you figure that? I mean it could be very well that the PSU is dead?
While touching the PSU just right now I felt a little shock which made me wonder that something might be wrong with the PSU. So what I did was unplug the PSU from the MOBO and plug the PSU power cord in and turn it on. I felt a little shock again while touching the PSU surface. I don't know why but I think this is the issue as it might be sending extra voltage throughout the case into the MOBO preventing it from booting.

Any thoughts?
 
Based on the info given it was the most likely, IMO, the mobo, and with it not turning on it not turning on at all it seemed even more likely. It could be the PSU shorting, dying, or something else.

If it was sending extra voltage to the mobo it would likely blow, or do exactly what it is doing now. Do you have or have access to another PSU that you could switch out to test it?
It definitely shouldn't be shocking that...
