Help... im at my wits end with this one. My G4 is, at random intervals, and for no readily apperent reason, making a 'ding donnnng noise... Sounds like a doorbell, or the doors closing chime on NYC subway cars. There are no apps running when this happens, and
AGH! it just did it again!
.. anywhoo... and i cannot pin down what's causing it. It is happening at random times, and random intervals.
