Intel D865PERL motherboard won't boot, no POST
Posted on 2005-04-22
I'm trying to bring back to life a nice custom built rig that has an Intel D865PERL motherboard with a 3.0 Ghz P4 and 1 Gb of RAM. The owner said he was blasting the dust out of the machine. When he plugged it back in it wouldn't boot.
- removing extra PCI cards (TV tuner)
- swapped in another AGP video card
- reseated RAM
- swapped RAM banks
- replaced RAM with different RAM
- remove everything except for CPU and RAM
- test power supply with testing device
- swapped in a different power supply
With all of the above, the result is always the same. No POST beeps, no video, fans run, motherboard LEDs lit.
If I remove all the RAM I can get three long beeps in POST.
A few things I might still try:
- blast machine with high power air stream from an air compressor, maybe some dust got lodged in one of the slots and is shorting it out?
- double-check for any loose screws or something shorting out the board
- swap in a PCI video card and remove AGP (this has worked on another system in the past)
- install RAM in another machine
- install CPU in another machine (this might be a lot of work)
- reflash BIOS by setting the jumper to reflash and booting a disk per motherboard manual instructions, maybe BIOS got zapped
I suspect the motherboard has gone bad. But, I need to prove that (or fix it). Whatever's wrong I need to be able to tell the owner what it is, rather than "maybe CPU, maybe motherboard, why not just replace both".
What would you do next?
