Weird Power Shut Down

This might not be a motherboard problem, but this seemed the best place to post. I'm in the process of setting up my new PC. I disconnected everything from the old PC to move it. I plugged in different monitors and a different Microsoft wireless mouse to it and started it up. The PC just shuts down after about a minute or two of operation. I thought it might be the OS (Vista) so I went into the BIOS (ASUS P5K) after rebooting and it does the same thing. Any ideas what might be causing it? I just replaced the video card and power supply a few months ago. The other device left are the SATA CDROM, a 3 drive RAID array, and a fourth drive.

Thanks for any help,

This actually happened to me on a build awhile ago. You have to put so much force on those stock pins that it doesn't seem natural to do over a sophisticated piece of circuit board. I figured it out because I run sisoft sandra....surprised you found it so quickly.

Not luck. Good basic troubleshooting.

You go back to when it was working. Then PC stops working. What changed?

Oh, I moved it. Hmmm. Maybe something came loose.

That's a combination of logic and checking the simple stuff first.

But not luck.
