High-pitch lyd fra computer - HJÆLP!

    Hej Tweak,


    Jeg håber det er OK at jeg kopierer mit problem fra et andet forum, da jeg skrev den på engelsk der. Jeg har et kæmpe problem, som jeg håber I kan hjælpe med.


    "Hello everybody,


    I have been
    having a huge problem this last month with my computer, which I hope someone
    will be able to help me with.


    The problem:


    A high pitch “squeak” sound is coming from “inside” my PC. It appears to be coming
    from my graphics card or somewhere above on the motherboard. I am not a
    hardware geek at all, so in all honestly I really do not know. I am almost sure
    it is NOT coming from my fans or my PSU, though it does sound like a voltage
    problem.


    Here is a VIDEO I filmed of my PC making the annoying sound: http://www.youtube.com/watch?v=_TjjVh-ov6w



    The facts:


    • Thenoises are random – and not related to anything. They will appear when I’m doing nothing, and they will appear when I’m doing loads of stuff.
    • The noises last between ~1-7 seconds
    • The noises started occurring AFTER I installed my new SSD: http://ocz.com/consumer/vertex-3-sata-3-ssd - I had never heard them before. I
      cannot RMA it, unfortunately. After installing my new SSD, I formatted my PC
      and installed Windows and that drive. Note: I am almost 100 % sure that the
      sounds are not coming from the SSD or HDD.
    • NO sounds during startup or in BIOS
    • People can hear the sound through Skype, EVEN WHEN MY MIC IS MUTED (!!) I find
      this very odd, and I hope it might be something to help locate the problem.
    • Some days there are sounds all the time, but I have tried going 5+ hours without
      sounds.


    What I have tried already:
    ·

    • I have tried unplugging my secondary HDD.
    • I have tried disabling EIST mode in BIOS – read it somewhere on a forum.
    • I have tried cleaning my PC of all dust.
    • I have tried to make sure that all cables are properly connected.
    • I have tried connecting the PC directly to a wall socket, to see if it had
      anything to do with that.

    My PC specs:


    Intel Core
    i7 2600K @ 3.40 GHz
    Gigabyte Z68AP-D3 Motherboard
    8 GB Memory – Kingston HyperX DDR3
    NVIDIA GeForce GTX 580


    So, that’s the specifics of my problem – I really hope someone will be able to help me
    with this.

    Lyder som coil whine. Kan være fra grafikkortet eller måske strømforsyningen.


    Det med Skype er lidt mærkeligt. Coil whine kan godt give elektrisk støj udover bare den støj man kan høre, men den støj burde ikke ende i Skype. Jeg kunne forstå hvis det kunne høres i dine egne højttalere eller sådan noget, men i Skype... meget mystisk.

    Det lyder meget som coil whine, jeg tror at det er tilfældigt at det er efter du har fået en ssd. Prøv at køre med integreret grafik, så kan du se om det er grafikkortet der er synderen. Hvis lyden stadig er der, så er det sikkert strømforsyningen.


    Gaming PC:
    Microsoft Windows 10 Professional 64-bit
    Intel Core i5 3450 @ 3.10GHz
    2x4GB Kingston HyperX Genesis PnP @ 1600MHz
    MSI Z77A-G45
    Sapphire HD 7870 GHz Edition OC 2GB GDDR5
    64GB Kingston SSD + 1TB Samsung HDD
    Dell Ultrasharp 23" U2312HM

    UPDATE: Jeg fandt ud af at lyden rent faktisk kom fra mit grafikkort, ved at gøre som masy skrev ovenfor. Jeg har nu kontaktet dem der har lavet min computer, og de har bedt mig indsende grafikkortet så de kan sende det videre til ASUS for en reperation / replace af varen.


    Så må jeg jo overleve med integrated graphics i mellemtiden :)


    Mange tak for hjælpen.
