Catastrophic Shutdown after chime on XP SP2, Toshiba Satellite S103

I've been having this problem for about a week. It's happened maybe
four times.
(1)There's a chime, alerting me to some problem. No application seems
to take responsibility for the chime. There's nothing in the Event
Viewer, and no popup box. It's not the battery, as this happens when
the laptop is plugged in.
(2) Ten minutes or so later, the laptop shuts down. It just turns off,
as if the battery were removed. None of this mamby-pamby 'would you
like to save your work' malarkey.
(3) It won't start up right away, and the little lights are all off.
Eventually, the power cord light, over the electric plug icon, will
come on, and the laptop will be startable.
(4) Windows starts up normally. It doesn't give me any guff about
having been shut down improperly, which is suspicious.
What's up? Could it be Google Desktop Search? I installed that and, I
think, the T-Mobile client application at around the time this started
happening. McAfee VirusScan Enterprise 7.0 notices nothing amiss.
Help!
