    This kind of question is asked frequently. If your machine isn't
    panicking (check the system console, and make sure you're not running
    X there), it usually means you have failing or marginal hardware that
    is unable to keep up with peak loads. Try replacing your power
    supply, or putting it behind a UPS that can condition the power if
    your AC supply is dirty or unstable.
