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.
