Athlon64 help

I recently bought a Athlon64 3200+ and a Gigabyte K8N Pro motherboard. I installed it in my tower and when I turn on the computer, it posts but immediately after the memory check it reboots. I thought it might be the memory so I replaced it but I still have the same problem. I then thought maybe my water-cooled heatsink wasn't making proper contact and the rebooting was caused by the thermal protection built into the CPU. I took it off and sure enough, the processor is only half-covered in heatsink compound from where the heatsink was making contact. The CPU was warm to the touch. So I remounted the heatsink and added a peltier between the CPU and the heasink to help it seat better and improve cooling. I tested the watercooled heatsink with the peltier before mounting and the cold side of the peltier built up a small layer of frost so I know that it is working properly. After remounting, I still get the same rebooting problem. I am thinking that the CPU may be toast but if that were true, it probably wouldn't still be able to post? Any help would be tremendously appreciated. Here's my setup:

Athlon64 3200+
Gigabyte K8N Pro
Asetek WaterChill watercooling kit (CPU and chipset)
2x256 MB PC3200 (Samsung, from the list of Intel recommended PC3200)
Antec Sonata w/380 W PS
Abit GeForce FX 5200

 
Do you have anything plugged into the CPU fan header on your motherboard?
If it doesn't see a fan pulse, the system will think you're starting it without a CPU fan.

 
I was actually thinking about the fan header after I posted. The only fan with a header in the whole system is for the power supply since the WaterChill fan has a special connector. If I plug in the power supply fan header into the CPU fan header, will that read correctly?
 
I figured out the problem. Not enough juice from the power supply. I disconnected all the drives and sure enough it booted fine. As soon as hard drives and CD drives are added, it starts doing the rebooting again. I guess 380 W isn't enough. I'll have to try my 550 W power supply. Thanks for your help KGBMAN!
