Default Computer making odd pressure release noises

Ladies and gents,

I have an unusual problem. Occasionally my internal PC speaker makes a high pitched squeel all by itself; it sounds exactly like my cars A/C system which starts out high pitched and then slowly winds down like it is releasing air pressure through a valve. Very odd, I have never heard of this before. It will easily do it 5 or 6 times a day if not more. The sound is not always the same, it is unlike ANY error code I have ever heard and I do a lot of computer work.

The system works perfectly but I would sure like to know what it is.

My motherboard is:
GA-MA78GM-S2H (rev.1.0)
GIGABYTE - Product - Motherboard - Specification - GA-MA78GM-S2H (rev.1.0)

Thanks alot,

- Jesse

Guess nobody's got any ideas on the subject.... only time I've heard something remotely like the sound you describe coming out of electronics was a TV on it's way out (tube finally went).

Maybe something weird like building up voltage on the ground plane?

Guys I was so wrong, I knew I should have checked. My internal PC speaker is NOT hooked up, yet it still makes this noise. All the capaciters look good and everything is clean and the PC still functions awesome. I am now more clueless than before.

Any ideas lol,

- Jesse

What exactly do you mean that the internal PC speaker isn't hooked up? Is it not an on-board speaker?

That's really creepy! Not hooked up!
Maybe you should try a little exorcism.

I do have a bad bearing on a fan sometimes from a cold start it is really noisy, but it is one my Anteic Tricool fans and not my power supply. Could a regular fan emit an electrical noise because it most certainly is not a mechanical noise that I am hearing. Bad couple days lol my PC is demon possessed and my water injection system on my car is flooding my engine lol. My PC is normally dead quiet but then it just lets out an electrical screech; I am baffled. it really sounds like a charge is being released to the internal speaker which is not hooked up or something lol
