Board Not Responding On New Build

By bob ·
Just put this PC together.
Intel D875PBZ board and P4 2.8E processor
2X 512 megs of PC3200 dual channel Corsair
60 gig SATA hard drive
8X AGP graphics card
Problem:
push the start button on the case and everything lights up, fans start, keyboard lights up, heatsink fan begins to run, but for less than a second.
It will do this every time that you push the start button.
All jumpers have been double checked as well as case connections.
There doesn't seem to be a short between the board and the case.
What could be the problem?

This is most likely a heat issue.

Make sure the heatsink unit was installed correctly. The heatsink may not be touching the CPU fully. Also make sure a thermal paste was applied.

If this does not resolve the problem, it?s got to be either motherboard or memory. Use one RAM only and see if this corrects the problem. Otherwise, it is the motherboard.

Make sure the CPU fan power connection was not loose.

If you have a VOM, make sure the fan is not grounding out.

"There doesn't seem to be a short between the board and the case" And you determined this how? Did you take the board out of the case? I know it is a pain but to rule out this possibility, that needs to be done. On more than one occasion I have glued the little brown cardboard washers on the mobo mounting studs (standoffs) even then one board was fine until I tightened the mounting screws. Once again it would short out. I had a MSI board not to long ago that was acting the same way as yours. This board, as it turns out,was a combination of the PS & and the type of ram I was using. Short time to fix this boards requirement but an extended time to ascertain what was needed. Good Luck

It's one of those X90 heat sinks and it was quite a process to get it in place. Pretty sure it is in properly and has enough thermal compound. I don't see it overheating in a matter of less than a second. Is this really possible?
I did take the board out and check it. I even touched a little elmers to the standoffs so that the fiber washers would stay in place when I put the board back.
