Hi,

I have a Toshiba Satelite P20, every now and again it just turns off. I have eliminated a problem with Windows, as it does the same when running the Ultimate Boot CD.

I recently installed a new hard drive as the other one failed, however the problem still occurs whether I have the HDD installed or not etc.

The laptop boots into Windows fine, but will turn off at any time w/o warning. I believe it to be a problem with with the PSU as there has been various problems with it in the past.

Any ideas as to what I can do to work out the cause of the problem?
