1.  Following page contains beed codes and explainations.
http://www.amptron.com/html/bios.beepcodes.html
    Try resetting CMOS via jumper.
2.Please read following
 http://www.pcguide.com/ts/x/comp/mbsys/cmosClearCMOS-c.html
   This procedure will clear BIOS settings which may cause your system not to boot and let it boot from factory default. You wont loose any data in your PC
3.I would have to agree that it is probably a motherboard or CPU issue.  And could be a power supply.  But most likely since you stripped it down, that it is probably the motherboard or cpu.  And most likely the motherboard
4.Remove All unnecessary hardware. But Cpu RAM and video card.  Verify power supply is working (very important step).  Verify System speaker is properly attached.
If no go and no beeps replace cpu with a known to work cpu or test on known working system
If no go and no beeps replace motherboard.
By now you should  get POST or a warning beep of some type.
Be it ram or video.

9 short?  Reset BIOS.
combination of short-long? Possible motherboard damage.

What is the pattern of the beeps?

did you replace both with the same model ?
check if the processor is correctly installed, and also the heatsink is correctly mounted, AND the fan running

No, just the motherboard.  The ram was fine.  I only received error messages for the processor, powersupply, and motherboard; not ram

cool...did you read my first post  and alegart's first post...we both said the possible reason would be motherboard.

"3.I would have to agree that it is probably a motherboard or CPU issue.  And could be a power supply.  But most likely since you stripped it down, that it is probably the motherboard or cpu.  And most likely the motherboard"

9 short?  Reset BIOS.

You got it!  I didn't think it was possible for a computer to be in such bad shape.  3 beeps (processor) then 4 beeps (power supply) then 9 beeps (motherboard)
