Instant unexpected shut downs

[Pamela G]

This has happened twice now. Cannot seem to find out what is going on, nor
is it happening often. But in the last week, just as I am sending an email
the computer clicks loudly and shuts down completely. No warning; nothing,
just a black screen. I need to hit the power button to boot up again, and it
lands on the choice screen asking how I want to boot up because it shut down
improperly last time. The email is gone, no record of it in drafts or sent,
and I am not really sure that is part of what triggers this. It just
happened to be what I was doing when the shutdown occurred.

Toshiba Satellite A205-S4629
Vista Ultimate 32 bit
Centrino Duo
2 Gig RAM
using Windows Mail, Avast Anti-virus (no-email scanning)
on a external fan pad for cooling, so overheating is not likely an issue
cable internet, firewalled

So, questions: where would I find a log or error for this since I am not
getting any hints in the shutdown and I didn't see anything in event viewer
except a critical note that there was an unexpected shutdown and related
services issues. And, any ideas on what is happening and how to stop it?

Thanks
Pamela

It is unlikely that you'll see anything in Event Viewer since this
sounds like a hardware issue. Contact Toshiba tech support for
repair/replacement.
