Strange beeping coming from my iMac for some reason

    I was just sitting here watching seinfeld and writing an E-mail (I think VLC and Firefox were the only apps running) when this strange high pitched beeping started.
    It was quite high pitched, had like a slight quaver in it. Kinda like a midi file of a grasshopper or something. It kept going at like 1.5 second intervals.
    Um my bluetooth keyboard is running outta battery, but I doubt that's it.
    Dunno what other info you need.

    OH yeah, intel imac 20", the first series one.

    I restarted and it stopped.

    Anyone know anything about this or if it's something I should be worried about?

    Its just your mac communicating with the Mothership.

    No seriously... only time ive heard things like that is when a power supply might be having issues or an inverter on a display was going.

    Either the processor or power supply in some computers (Mac and otherwise, but I'm specifically thinking of my G5 tower) can make a kind of quiet, high-pitched, "skritchy" noise when under load.

    It's at least possible that's what you were hearing, though I'd think it would be more common if that was it. I assume you're sure it's not hard drive access (maybe triggered by a background process like Spotlight)...
