I have a toshiba M45 stsrts up then the screen turn black and the lighted power on button gos out any suggestions and if i have to take it apart is there anything i should know
thanks

format the PC then install the OS and other application softwares you wish to use.

Are you able to enter the BIOS? try pressing del or F2 at start-up.

Does the computer restart or does it just turn off and stay off?

Do you know if you have a system restore partition or the XP installation disk?

If you can use it a few minutes and then power goes down, it looks like a heat problem...

I would think there is a heat problem. Your computer is shutting itself down to avoid heat damage.
