HP hanging at post screen

Specs: Windows vista?, AMD x3 8400/ 4gb
Hey all I have acquired an HP m8417c which is currently not working and hanging at the post screen. I have gone through all of the usual steps of reseating all components and cables, running with minimal hardware (processor and 1 stick of ram & monitor were the only things connected) and clearing the CMOS on the motherboard (pulling the battery as well as moving the jumper did not seem to have any effect). Nothing has seemed to work and it still hangs and is not responsive to any keyboard input either. I am not sure what happened to the computer before i got it and would like to get it to work but I need some help from everyone on what the problem could be. Any suggestions would be helpful.

Thanks,

Acquired eh? Where did you get this heap? (...for how much $, and if you got it free...put the end of a chain in it, fill it with cement, then use it as a boat anchor).

Just another stupid saying...

Originally i was fixing it for a neighbor. i had told her it wouldn't be an easy fix (possibly will need new motherboard/processor) and she didn't want it back. I don't want to just get rid of it because i have many uses for it. Whats your take on it? bad motherboard or cpu? fixable?

Usually when a PC doesn't POST (Power On Self Test), the CMOS (which contains the BIOS - Basic Input Output System) is corrupt.

You could try CLEARING the CMOS. It could be a memory issue, or power supply maybe, or CPU/Heat sink issue, but chances are it's the CMOS.

Years ago you could just replace a removable CMOS chip on the motherboard, now they socket & solder them into the motherboards so you have to replace the whole motherboard (probably so they can sell more motherboards?).

I have attempted to clear the cmos multiple times through the jumper on the board as well as removing the cmos battery for 24 hours, neither of which had any effect (no messages saying it was cleared nor has the problem gone away) Like you said maybe the cmos is just "dead"
