PP6 pc won't boot

[hwright]

I have a PP6 motherboard, which will not boot.


The BIOS performs the system inventory.
It displays the hard drive and cdrom on the screen (only if I set the BIOS to Auto and the boot up sequence to Cdrom, C, A.)

The logo ('Energy') disappears from the screen.


(THIS IS WHERE IT STOPS)

It never gets to the point where the BIOS will search for and label logical devices (COM and LPT ports).

I don't know what to do as I have changed all the drives with working drives from the other PP6 machines already configured. I have changed the RAM, IDE cables, VGA card, and the slot the VGA card was in. I have checked all the jumpers and voltages. They are correct.
I remounted the motherboard in case it was shorting somehow. It wasn't.

I have changed the CPU.

Nothing has helped. Any ideas?

1. Make sure the CPU is supported by the motherboard.

2. Pull everything but the video card, CPU and memory, and try it. If you still get no video or POST I would say ground problem, but you say you've checked that, so if you get no beeps or POST, I'd think bad motherboard or CMOS chip. If it makes it through POST, it would be bad memory.

3. If, at this point you get video and POST, connect other components one at a time, starting with floppy drive. That will avoid having to pull everything and start over, whatever you add that causes trouble is easy to figure out...

Soon as I come up with all the answers...they change the questions!!
