"BAD_POOL_HEADER" Message + High-Pitched Tone Coming From CPU

My two-year old HP desktop running Vista with 3gb RAM has worked well until recently, when this sometimes happens: When I boot up the cold computer, the blue screen of death (BSOD) appears with the message "BAD_POOL_HEADER" followed by something about using the safe mode to remove or change components, and the following technical info: "STOP: 0X00000019 (0X00000022, 0X00000000, 0X00000000, 0X00000000)." I has happened only twice in the past 15-20 boot-ups, and it happens only at boot-up, i.e., it does not happen once Vista has started. When it does happen, Vista never gets a chance to start before the BSOD appears. The two times it's happened, when I shut down right away and reboot, it happens again; however, if I wait five or ten minutes and then reboot, Vista starts normally and all is A-OK. It doesn't appear to be a temperature issue since it only happens at (cold) boot-up. What's going on?

If it only happens on cold boot ups, it could be a power problem, either with the power supply or the motherboard.  The high-pitched tone could be a "singing" capacitor, a sign of failure.  You can try replacing the power supply, but if that doesn't work, you may need to replace the motherboard capacitors (see www.badcaps.net for examples of bad ones) or the motherboard itself.

My problem seems to have been solved. A friend suspected that the problem was caused by an overheating CPU. He pulled the CPU and saw that the coating of silver oxide on it had dried out. So he put on a fresh coating of silver oxide and that seems to have solved the problem. It's been one week since he did this, and so far so good.

Keep your vents clean, too - excessive heat is a common problem with laptops.
