P4P800-E Delux shutdowns

I just ordered it installed the CPU 2.8Ghz Prescott GF3 ti200 and 512MB stick of Corsair ram.

I turn the machine and abut 10-15 seconds after I turn it on it turns right back off.

I pulled the CMOS battery hoping it would reset the BIOS but no luck.

I figured well maybe its the PSU. I plugged the into my working 450watt antec that is on my main machine and it did the same thing. The PSU thats in the machine is a 350watt Antec.

Any more ideas?

Fixed it.

The Heatsink was not seated correctly. Lucky that I didn't fry the CPU.

It's not luck; it's good engineering!

I really don't like the LGA 775 packaging because of the HSF retention mechansim. It's a real PITA, and easy to get installed wrong.

I wrote a guide that discusses how to diagnose reboots.
