Laptop randomly goes dead

  dobbin 13:56 20 Oct 06

My laptop from time to time suddenly goes dead with no prior warnings or beeps. It can sometimes run for several hours without doing it, at other times it will run for only a few minutes after boot up.

It starts up again as soon as the on switch is pushed, does a disc scan and then boots up quite normally and runs ok until the next time everything goes off.

I have done full virus scans and spybot scans and its not the battery as it is plugged into the mains when it occurs.
Its 3 year old tiny laptop so suspect it may be a bit of dodgy hardware. Does anyone have any suggestions?
