    My PC emits this high pitch sound...

    It sounds like its coming from around the CPU... It's a continuous high pitch sound that can sometimes be intermittent... It isn't super loud, but it's like a dog whistle... VERY ANNOYING... I'm starting to freak out...

    My PC is a gaming Rig, and it could be anything. Up to now I've only found one hint that might help us find what it is. When I hold down the F5 key (refresh), the sound leaves almost completly...

    I don't know if this indicates anything... PLS help! :O(

    Don't capacitors start to whine when they are dying?

    You have no system info, What PSU do you have, I have had this with the ULTRA brand of PSU's.

    if its a Coil making the noise, then some super glue on it will fix it.... if its somthing else then you will have to buy new hardware of what ever it is thats making the noise.



    unless you can get away with an RMA.....

    my old GTX260 use'd to make the same noise when it was under Full load... its not going to die, unless you get really pissed off at the sound and snap the card in half :p

    Guess i was mistaken :(

    Get yourself a piece of plastic tubing 2-3 ft long & use it as a makeshift stethoscope....hold one end up to your ear & probe around with the other end until you pinpoint the source of the noise.

    It's chokes (inductors) with vibrating coils. It's not a bad thing, only that coils that give out noise tend to be inefficient as they're losing energy to heat and/or noise. It usually doesn't mean that they're failing. Have you overclocked your CPU with increased voltages?

    Chokes are those [usually black] cubical parts around the CPU socket or near memory slots and chipset.

    This. Or tape.

    i've had everything from mobos that squealed at load, to mobos that only squealed at idle, to finding out it was nearby devices like remote controls with LED's that had flat batteries, to the power pack to my dinovo edge.

    high pitched noises can echo and sound like they're coming from other sources, so use something like a cardboard tube from toilet paper next to your ear to try and narrow down the source.



    its usually not a sign of dying hardware, but it can be damned annoying. i'm over 25 and i hear this stuff quite often, and it pisses me off.

    I had the same thing.
    I think it could be the Vregs around the CPU

    How about the fact that the sound seems to be cut off when I hold down the F5 key (refresh button)...??

    I'm pretty sure that could help me find the reason for the noise...

    could be what i said earlier, that stresses the machine so it stops it idling, and the noise stops.


    try disabling CnQ or EIST (you never listed your specs), see if that changes anything

    specs:

    7 875k unlocked
    1 Radeon 6950 (unlocked
    2x 4gb (RAM) (1600 mhz - Ripjaws)
    Motherboard : ASUS sabertooth 55i
    CPU is watercooled with an ECO watercooler (thermal compound and everything...)

    I'VE ISOLATED the sound source. Altho it's hard to pin-point this exact position. The sound is coming from right above the CPU. I used a straw to find out.It seems to be located around the top right corner of my Coolit Eco Water cooler's FAN (that square pump attached to the CPU)...

    So it looks like its either coming from the cooling kit or ... considering what my ears were telling me... it could be one of those small cylindrical little metal parts that surround the CPU...

    I'm gonna try unplugging the CPU fan for a few seconds to find out

    try disabling EIST/C1E, if its like my housemates i7, that might well solve the problem.

    You haven't mentioned the PSU.

    Everytime I have had that problem it turns out that a less than top line PSU was the culpritt. Its not 'normal', dont ignore it. It is annoying as hell, sort it out.

    i've had it occur with top notch PSU's and its been the motherboard/graphics card at fault, and RMA has fixed it.

    PSU can be the cause, but its certainly not the only cause.

    PSU is definitely a source of high pitched noise.
    A customer returned an Enermax PSU due to high pitched noise.

    Does the squealing happen on load? My 2 ENGTX 460 Directcu sequel all the time when they are folding. Like the others had say, I wouldn't worry about it, usually a choke or a capacitor making the noise. It doesn't mean they are going to go out. Electronics just do that.

    It happens when idle... When I hit the refresh key and hold it... It kinda stops...
