Failed reset on Thomson PC

Hello, recently my laptop turns on and off by itself even though I reset it due to a problem.
My computer shows its normal loading screen and then displays a "restarting" message and restarts.
I would like to find a solution without having to consult a technician since my laptop is no longer under warranty. Thank you in advance and have a nice day.

    A "thing"...?

    1. It's not a square but a circle that moves from left to right and vice versa, but I don't know the name; it's not a box.
    2. @Quiquilou74For the moment, let it be, Windows may restart several times due to updates. This can take a long time depending on the updates and the capabilities of the PC.
    3. @fermiparadoxxI was just telling him to activate the notify function for restarts.
