    iMac hum
    Hi,

    I am a bit concerned about my 8 month old 20" iMac. There seems to be a faint hum sound coming from it. The hum sound is barely noticable but gets slightly louder when I touch the screen of my iMac to turn it around to get to the USB ports. When I move my hands away from the screen the hum sound goes back to normal.

    Is this normal?

    not exactly the same problem you are having but could be a similar issue and worth checking. look at my post here and see if this might be related to your problem.

    Thanks for the reply.

    This is not related to audio or the speakers.

    Its when I touch and put a bit of pressure on the corner of my iMac (just at the corner below the screen) that I hear a faint hum sound.

    I've tried unplugging things but I still get that sound when I touch and put pressure on the corner of my iMac by adjusting the screen or turning it around to get to the usb ports on the back.
