OK, so here's what happened.  I built the following machine:

mobo: Gigabyte GA-EP45-UD3R
GPU: gigabyte GT 220
CPU: Intel Pentium E5200
RAM: G.Skill 2x1GB PC2 6400

My kid was in the middle of an online game when the computer went dark and shut down.  When I turn on the power i get the following:

all case fans power up, hard drive starts to spin, all LED lights on mobo light up.  The stock heat sink fan starts to spin for about 1 sec then stops.  The power stays on for 2-4 seconds then shuts down.  After 2-4 seconds the cycle starts again and will repeat until PSU is shut off.  BIOS won't post and im not sure where to go from here. 

I've done the following troubleshooting:  tried startup with one stick of ram and get the same result with either stick.  disconnected all drives etc and get the same result.

Gigabyte says the system needs a GPU, one stick of RAM and a CPU to post.

Given that i would doubt that both sticks of RAM crapped themselves, how do i determine if the CPU, GPU or mobo are the culprit?  I don't have spares to swap in (yet!!).

Thanks for your help

What brand is your PSU?

Low-end PSUs tend to cause many problems to the whole computer.

Nothing replaced recently?  Overheating what with the days heating up toward Summer in L.A.  But yeah, PSU most likely.

Thanks guys, it was in fact the PSU.  It's a coolermaster psu.  Off to RMA it now!

Thanks again.
