PC Won't Start Up - Beeps

[winste]

Long story short, my PC had been restarting randomly.  I got a Bad_Pool_Caller error 0x000000c2 error.  Research suggested overheating of CPU.  Intalled a monitoring program and found it was consistently running over 60.  Took the case apart and found alot of dust.  Took CPU cooler (not fan just heatsink) off to clean.  Blew fans clean with bottled air.  Reinstalled everything.

Now when I try to power it starts and I immediately get two seperate tones that alternate twice.  Tone A, Tone B, Tone A, Tone B and then powers down.

Anybody have any suggestions?

When you took heat sink off and re installed did you re apply thermal grease to heat sink? Is heat sink re installed properly?

I did not reinstall thermal grease but am pretty sure the heat sink is installed correctly over CPU.

I would pull the heat sink and clean surface an re install grease. If you have more than 1 stick of memory remove and try with 1.make sure all connections are secure.

What BIOS is it?
Can you boot into Safe Mode?

XP and no, it won't boot in safe mode either.

I asked for BIOS type, but you may not know.
Reseat everything, as xavier said. While monkeying inside, you might have knocked something out.

I suspect that you have an Award BIOS and the beep code signifies a problem with the CPU.

*Unplug the computer from the wall and ground yourself*

1) Remove and replace the CPU - check for bent pins (if you need instructions, please ask.)

2) As previously suggested, remove heatsink and apply a thin layer of thermal paste (if you need instructions, please ask.)

I recently had a similar problem and found my hard drive had come unplugged.  In your case, it may not be a hard drive but as these guys have said, I would check all  of your connections.
