Computer Shuts Down After a Few Seconds

Specs: Windows 7
I just moved a build from an antec p180b to a cooler master storm sniper, and when I turn on the machine is only runs for about 15-30 seconds. When I turn it only again, it will only stay on for 2-3 seconds. After a minute or so, it returns to the 15-30 seconds of life.

I was able to access the BIOS and Windows would start to load, and their is no consistent point of failure. I removed one peripheral (an esata connection port in the back) and everything else is essentially the same.

What steps should I do to troubleshoot this? All the parts worked fine before the move. I was also careful to prevent static discharge, but didn't wear a bracelet. Could this have caused a problem? Also, I'm not sure if the case fans are hooked up correctly (the back plate and cpu fan do spin just fine). The power supply fan also spins fine.

There are also lights on the motherboard that vary from yellow to orange to green...

The build:

i7 920
6 GB Corsair XMS 3 DDR3 RAM
500 GB WD Caviar Blue
Gigabyte ex58-ud3r rev 1.0
BFG 8800 GTS
700 W Quad Silencer Power Supply

Have you entered the bios and checked what the temperatures are? Let the computer run a while as you are monitoring the temps. Are the dip switches in the correct positions for your setup? Any chance that an anchoring pin or some part of the motherboard is shorting out by touching the case?

The temperature on the cpu rapidly climbed after turning it on. I didn't see at what point it turns off, but I shut it off at 72 celsius. Should I clean the heatsink, or do I need to reset the CMOS?
