[Closed] Computer restarts by itselft

Hi everyone, I have a problem with my pc, it restarts by itseft after a while of using it. I don´t believe it happens because some specific program is used cause as I said it doesn´t really matter what I´m doing, it just restars.
I would appreciate any kind of help.
Thanks a lot.
