Major boot problem with Intel Board
The setup:
Main -------------- Pentium D 3.2ghz 800FSB socket 775 Intel Processor cooling fan (provided) Intel D945PVS LKR Motherboard Two 80mm fans Two sticks 512meg DDR2 PC5400 DDR2 (667MHz) - Geil XFX Geforce 6600GT PCI-Express 128MB DDR3 Drives ---------- Maxtor SATA-150 250 GB Sony 16x dvd burner Generic 1.44 floppy Power Supply ----------------- 450W (generic) The Problem: Put everything together, went together fine, no problems. When I go to turn the unit on I get Intel's splash screen from the board, lights turn on, fans are run, processor cooling fan is running, all of the sudden everything shuts off. So I go to restart and I got an error message saying that the board shutdown due to overheating. Then it shuts off. I try to re-start to get into the bios to see what temp. the unit is running at and now I can't even get to the splash screen. So, I shut off the unit, replace CPU cooling fan with a brand new one for the same processor I had laying around, nothing. Took out the board, reseated the processor, the RAM, the graphics card. nothing. Took out everything and reinstalled it (CPU, Fans, RAM, processor, CMOS battery, cards) left it sit for 10 minutes and then put everything back in, leaving out the front panel USB & audio devices and unhooked the 1.44 floppy. So the only thing running was the board, graphics card, hdd and cd-drive. I got the splash screen for a second, thought I had fixed the problem and then it shut off. Any thoughts of what to try next, my next move would be the power supply, although it seems to run fine and 450 W ought to be enough to run what is installed here. Does this sound like a board problem? Thanks!

what was wrong
The Fix:
I tore everything apart for a third time and noticed that the small piece of thermal coating on Intel's heatsink/fan (looks like a small piece of gray vinyl tape) had only covered roughly 75% of the area where the heatsink/fan touched the case of the CPU. I filled the rest with Arctic Sliver. Reattached the heatsink and the computer booted up fine. This was the first Dual Core (socket 775) I had put together, the heatsink seemed to be the largest problem. I found that you have to push harder than expected to get the pins to lock in. Ultimately, a loose heatsink and minimal thermal compound coverage was the culprit here.
