Processor pressure, no bios POST

vespahead
I have a computer that suddenly went black. Tried everything, including new Power supply, no go. Then I removed 2 sticks of ram and reseated the processor, got a POST beep. Then nothing. It seems that sometimes when i put pressure on the heatsink of the CPU it will give a post beep, but them not other times. Does this mean my processors bad?

GA-8KNXP motherboard
P4 3.4 Ghz
3 GB RAM

    As you know that the M'Board speaker works try reducing the unit to the bare minimum with just a CPU and see what happens now.

    If this works start adding one piece at a time till it either stops working or it assembled and showing you the POST Screen or booting.

    When you replaced the Power Supply did you use one that is supported by this M'Board it is a Dual Power M'Board so have you got all of the power Connectors to the M'Board plugged in properly?

    Reseated everything, no beep. I tried just the CPU itself, and no beep. Yes i have the required power supply, and it is plugged in properly.

    The computer was working fine for 5 years, then suddenly the monitor shut off and now it wont post or boot.

    It could have been damaged when the previous Power Supply died. CPU's very rarely fail in my experience an when they do it is because they have been incorrectly setup originally. I've never seen a failed CPU on a properly configured computer but I have seen plenty of Dead M'Boards.

    Whre you present when the system went black? Did you hear any snapping noises? Did you see or smell any smoke?

    If it made a difference by replacing the power supply, then the old power supply may have surged and fried the motherboard. Look for any discoloration on the motherboard. I've seen motherboards go bad, but I;ve never seen a CPU go bad.

    Yes i was present when the board went out. No sound or smoke smell. Checked all the boards and no signs of damage on any of the boards. The new power supply didn't make any difference.

    Once while trying to get a users self built unit up and running the first time, I ran across the same problem. No post but a little pressure on the CPU got a beep from the speaker. After some head scratching, replaced the MOBO and it worked fine. After some very tedious work with a low wattage (23 watts) grounded tip soldering iron, I found some bad plate-thru solder connections on the CPU socket and a scratched through trace near the same socket. Seems the user/builder had some problem seating the heatsink on the CPU chip. I now recommend that the heatsinks be mounted to the chip before carefully placing it in the socket. After cleaning up and repairing the MOBO, all worked fine. I've also encountered the same fault with memory sockets and heavy handed users trying to upgrade their memory.

    So do you recommend replacing the motherboard? Problem is i have a RAID 0 with the onboard GigaRAID, so i dont want to lose that data. Having trouble finding the same board, so i want to see if it's the processor or MOBO for sure.
