The advise of check the PSU is the easiest to test, especially if you have a spare.  Bad PSU's can do all kinds of weird stuff.  Test by using another PSU.

ONE WORD OF CAUTION:  SOME DELL PSU's are not wired the normal way.  If your system is one of them, and you put in a standard PSU, you CAN destroy the PSU AND the MB.  Be careful about that.  Check online if you think you may have a DELL MB/PSU,

Hi All,

I'm having serious hardware issues with my main dev box and it is now completely down.
It's a fairly high end custom system (RAID, custom cooling, etc) that I built myself and has been quite stable for several years.
The box powers up and the LEDs on the motherboard light. But it never reaches POST.
The M/B has an LED that displays the boot hex codes on the board as it goes thru POST. Nothing is being displayed.
I've tried pulling out the video card and disconnecting all the peripherals, but that didn't help.

I'm thinking that the motherboard may be the problem.
I'd like to take it in for service to have it properly diagnosed. Does anyone know of any good hardware repair places in town?
I was thinking of Data Doctors, but don't know if they are capable to handle something that is not from a major manufacturer.
Is Fry's Electronics any good?

Any help would be most appreciated. And the faster the better. :)

Thanks for your help.
Peter
