Why does Toshiba laptop locks up intermittently?

Toshiba laptop running Vista home premium locks up intermittently. There is
no pattern. When it locks up, everything stops responding and you have to
switch off/on the laptop. Checking event viewer, you get:

The previous system shutdown at time on date was unexpected.

I think when you switch off the laptop, above entry is generated. Could not
find any other relevant entry. I have done the following:

1.ruled out over heating.
2.Ruled out start up services
3.ruled out antivirus
4.ruled out power options
5.reformated hard drive
6.passed hardware diags

Still the frustrating problem persists.

Can anyone take on this challenge by suggesting what could be causing this
problem and how can it be resolved?

Tried a memory test, www.memtest.org ?
You would need to run the above for several passes/hours

You have made sure that all of your drivers are up to date, correct?

I would rightclick a Command Prompt icon in accessories, and 'run as
administrator', then run the command:

perfmon /rel

This may report something more informative.

I had HUGE problems with a Toshiba Satellite - so many lock ups that I took
it back to the store and exchanged it for an HP Pavilion. I tried everything
on the Toshiba and could not end the lockups and BSOD - it was unusable.

Sorry I don't have an answer, but thought I'd let you know it might be the
hardware.

You could also check Event Viewer.
