Chirping sound

I assume by coming from the PC, that the sound is coming from inside the cabinet.

My best guess is that one of the fans is starting to fail.

With the PC off, spin the blades on each fan.
They should all spin smoothly.
Some may have a magnetic cogging effect as they reach a stop, this is normal.
Any fan that binds, or makes noise when spun by hand should be replaced.

If it is the power supply fan, I would consider getting a new higher watage power supply instead of replacing the fan.

If you have a PII CPU with an Intel fan, it may be difficult to change the fan.
This would be a good oppourtunity to upgrade your CPU speed.
Check what CPU speeds the motherboard supports, and check out the slot 1 CPU section at www.compgeeks.com

If the chirp is coming from the system speaker, then some event is triggering a system sound that uses the PC speaker.

When I encountered a "chirping" from my system, it was the built in overheating alarm. I would recommend you check your temperature settings on the system if you can. I would also check your fans and airflow...

Sounds like your pc has one of 2 possible problems, A chirping noise means either your Hard drive has readers arms failing and should be replaced witha new hard drive, or your power supply fan, or CPU fan bearings are going, chirping can only be caused by moving parts within the PC, so therefore these are the only parts that could make that noise. The wuickest way to find out is to open the PC case and start the PC then listen to each area and visually inspect it this will usually tell you if it is a fan, Power supply fan, or hard drive.

If it is an electronc chirp, as opposed to a mechanical one, I think I may know your answer.

I have a laptop with an IR port. My Laserjet also has an IR port. Periodically the OS will scan to see if other IR devices are present, and chirp if it finds one. If this is the problem you should see the IR icon beside the date on the menu bar.

The term "computer bug" actually came to be because of a real live bug inside a computer. Perhaps you've stumbled upon the first computer "bird".

You could actually have a covey of problems. This might fly in the face of logic, but it's worth checking to see if any of the moving parts are feathered in any way. And check to see if pieces of debris have flocked to form a nest in there, perhaps around the fans, robin the free flow of air. One piece of debris might be harmless, but toucan reallyfowl up the works.

I initially thought that answer number one was eggsactly what was causing the problem. But then answer number two showed its plumage, and it may have wings as well.

Keep us abreast of what’s going on. We’ll preyyou get a solution.

Actually, this answer is no more than a lame attempt (emphasis on lame) at “bird-brained” humor (obviously), and is not intended in any way to simply grab a share of the points. So please, reject thisanswer. In my estimation, numbers one and/or two are correct.

But then again, perhaps someone else has a pigeonholed answer. Then I'll have to eat crow. (That would make me feel like a real dodo.)

Maxwell’s maxim:

It’s hard to soar like an eagle when you’re cooped up with a bunch of turkeys.
