Brand New MSI P4N SLI Dead At 4 Days Old :(

[Nighted]

My new mobo died after 4 days out of the box and I could use some advice as I'm going to have to figure out what to return to the online company that I purchased it from. Could it be the processor?

I put together a:
MSI P4N SLI mobo with a 3ghz Celeron and 512mb chunk of Geil 667 RAM with a 480 watt Mutant Mods PSU. :Q

After 4 days of operating fine, yesterday I was talking on Skype and my machine went cold, lights out.

Tried rebooting, can hear the CPU crunching, fans and lights working, DVD drive blinking, hard drives are humming but monitor remains in sleep mode and there are no POST beeps to be heard. Tried resetting the CMOS, nada...no luck. Tried booting a few hours later and the monitor came on and I got into the BIOS so I let it sit like that. After a few minutes it died again. Does this mean anything to anyone?

Would a dead CPU prevent the BIOS from being accessed or is the BIOS able to operate without a CPU?

Would a dead mobo be able to boot again but only for a brief time?

Argh!!!! Confused

More sys info:

Motherboard: MSI P4N SLI
BIOS: AMI (version? Don't know...mobo is dead)
CPU: Intel Celeron D 340 2.93Ghz
RAM: Geil 512Mb PC5300 677Mhz DDR2 X1 Slot
GPU: ATI Radion 8Mb PCI (I have no PCIe card at the moment)
PSU: Mutant Mods 480 Watt PSU: +3.3V/30A, +5V/45A, +12V/26A
HDD: 30Gb Quantum Fire Ball IDE Master/120 Gb Maxtor IDE Slave
DVD: LG GSA-4120B
OS: Windows XP Pro SP2

...all housed in a Lian Li case with mobo risers all in the correct places. No shorts anywhere that I can think of.

Have you tried another power supply ?

OK, that is not a good sign

But serious, the PSU would be the likely culprit. But try disconnecting all drives, non-essential fans, and add-in cards (PCI/PCI-E) from the mobo & PSU and try booting.
If you still get noting pull the graphics card and RAM and see if you can at least get POST beeps.

ATI Radion 8Mb PCI graphics card is really running on a low budget. I would suspect that would be the first thing to go.

Nope, it's still FUBAR...I don't get it. Like before, it POSTed because I heard the single beep. When I restarted it, no beeps, so no POST. I went out and picked up an Aspire Power Supply Tester. Tested my PSU and there is nothing wrong with it. Pulled the RAM, still no beeps, so now it's stripped down to the mobo and CPU.

Would a dead motherboard do this? Maybe it's that ghost from The Sims....

Anyway, I called a couple days ago and got an RA from the online store where purchased. I think I'm just gonna send it back because if the CPU were dead it wouldn't be making noise and the board would still POST...right?

Try another power supply, it sounds like power issues, and no i wouldnt post with a bad cpu

No, I tested the PSU with a tester. It's fine.
