I forgot to mention that if I run defrag or a full virus scan it will shut off also.

I have a Toshiba Satellite 1955-S801 laptop which is just a little over a year old. Randomly it will shut off like someone unplugged it, no warning other than sometimes I hear the fan running. Lately thought it seems I don't hear the fan as often when it just shuts off. If I immediately reboot it will many times shut right back off and may do this several times in a roll if I keep trying to reboot. If I wait for approx. 5 minutes or so it will then reboot. I keep the little air vent on the bottom of the laptop clear by vacuuming often. What could be causing this?
Thanks in advance for any help,
Devorah
