    I have a couple 21" bushed alum Macs. They are running 10.5.8 I beleive. These computer will just shut down. I can leave them on a week and they will be ok if I dont use them for anything. If I use them they restart. It happens now matter what program is running. Any Ideas? Should I reformat?? Or is it a hardware problem?

    Tried different power outlets or circuits yet?
    It seems rather strange that a couple of iMacs have the same symptoms.

    Those iMacs had/have issues with flaky power/dc/inverter cables, and the symptom is random shutdowns. Since it's just a cable, it's not a particularly expensive part, but it's quite a daunting replacement. Alternatively, it could be bad power supplies. I've seen a fair number of those, too.

    The simplest thing you can try is an SMC reset, and just hope that fixes it. If you can find something that consistently duplicates the issue, that would make it a lot easier to figure out what the cause is. Otherwise, any attempted diagnosis will effectively be just a guess.
