ML370 G4 boot problem freezes no video

Hi,

I have a ML370 G4 that I rebooted the other day and it didn't come up. Symptoms were:

1. fans spin as normal
2. array SCSI disks spin up and go green
3. CD flashes once
4 All motherrboard LED's are green. No video display whatsoever
5 All front led's are green

I opened the case and there is a heat sink normally attached to a square processor like board next to the two actual processors. one of the U shaped holders for the spring clip of the heat sink has come away from the board and the heat sink became detatched.

I assumed that the system board had overheated and managed to find another on ebay brand new, preferable as HP were quoting 5 days delivery!

Problem is, now that I have replaced the system board, I have the same issue!!

HELP!!

Thanks for all of your help. It was a dodgy DIMM. Had to replace m/board anyway because of the broken connector for the spring clip. I assume that the broken clip hit the DIMM on the way down (as its directly below) and shorted it out or something.
