Question One day the computer turns off by itself and the next day it seems fine ?

[cloa513]

Yesterday the computer suddenly turned off and then either wouldn't turn on ( no light) or would turn on for a second or later turn on for a few minutes.
Today it is OK.
We had this issue before and then fine for a few days. Is it mostly the power supply?

This is a Fujitsu computer bought direct 2 years ago.
My wife is controlling and I am getting her to deal with Fujitsu.

Welcome to the forums, newcomer!

Is it possible to parse the model for your Fujitsu prebuilt system? I'm not familiar with Fujitsu's support method but you should be able to use your prebuilt's serial number and bring up a page for all relevant driver and BIOS versions on a support page/portal. You might want to also check and see what version of Windows 10 you're on at the time of writing. You can right click Start>System and the version for your OS will be stated at the bottom of new pop up window.
