GA-G33M-DS2R not working

[zipdrive]

built the titled motherboard about 2 months ago, 2 gigs ballistix memory, 160gb hdd, evga 8800gts video, Thermaltake 600 watt power, e6600 proc.
It's been working fine. Got home from work this am, computer powers up, fans turn, no startup screen, then powers up, then powers off.
Of course, my first thought is power supply, but I will have to play with it tommorrow, as I'm working now.
Any suggesstions as to things I could try?

Also check your ram.

That usually happens when board detects a hardware fault. Ie, overclocked too high, bad memory etc.

well, I used a different power supply, tried different memory configs, used on board video...nothing worked. I placed all the components minus the motherboard into an Intel BX2 I had, and everything worked perfectly.
Got an RMA from Gigabyte....we'll see how it works out.
