    Default Computer high pitched squealing noise?

    Hi

    I recently built a computer for a mate and he's told me that every so often it would make this high pitched squealing noise for a few minutes then stop. Just needing to know what this noise could be?

    Any Ideas???


    Thanks

    Take the side off the case when it is making the noise and see if you can narrow the location down. As mentioned, video card fan is a popular culprit. You can (carefully) try to stop the fan spinning with the use of a pencil and see if the noise immediately stops.

    Usually power to video card, if it uses 6pin power then check that cable

    It's not the video card fan as this stopped working and replaced it.

    Video card has no extra PCI-E power connector.

    I just googled it and found this :

    if its not mechanical, it could be a capacitor or inductor squealing, this can happen as they overload or heat. and could be anything from psu, mb or vga.

    I'm so hoping it's not the Mobo.

    Are you sure you are not picking up the sound of a losing Australian cricketer? PJ

    When I was younger I heard but didn't listen.
    Now I am older, I listen but cannot hear.

    If it is not broke, don't make it broker by trying to make it better. (This applies specifically to PJ)

    Is it under any particular conditions that it does it? I know when i stress test my graphics it sorta whistles, could be under load when it does it?

    most likly power supply. they typically squeal a high pitch when going out of spec (ie starting to go faulty).
    Tweak it till it breaks

    Is the sound coming from the monitor or the system case? I've had old CRT monitors make a very high pitched squealing sound at times. Most annoying too!

    Don't know where they got that from.

    Inductors/transformers are a common noise source through magneto-restrictive effect, which makes them whistle, squeal or sing. They often do this even in the absence of any fault, especially if the winding is not secure or the core is cracked. However, capacitors do not squeal. In well over 40 years in electronics I've heard capacitors sizzle, and I've heard them hiss, and those sound effects are usually followed by a loud pop or bang, but I've never heard one squeal. Once a cap starts making noises it usually dies within a few minutes.

    Cheers
