Greetings!

Could you inform us with what recent activities (physical/digital) you did with your laptop before this screen appeared?

Also could you provide your device model and the operating system you were running before the problem?

I turned it one and it said something Like that before and it shut off and then I turned it back on and it came up as the normal computer login screen so I logged it and everything was fine so I tried to play a game and it shut off and I turned it back on and it was at this screen
