Windows 11 blocks

[G_Ceretti]

Hello everybody.  I have a very strange problem.  Till yesterday my laptop with Windows 11 worked well but today all is blocking. I do not know if I give some command with the keyboard but suddenly I have a black screenshot.  I shut PC off and then on but from this point on I can work only with CTRL key pressed down : if I leave this key a black screenshot reappear and my PC goes off.   Restarting is quite normal but very soon black screenshot again and so on.  I can work normally only if I press down the CTRL key.   Maybe somethig goes wrong during power on ?  Maybe the start configuration is corrupted ? May be my PC has some cruel hardware problem ?   Could someone help me in solving this awful problem ?

Thank you in advace   Jerry

I recommend to update display driver to latest version.
Make sure your Windows 11 with a valid and genuine license.
Also, install latest updates available to you.

Let us know if this helps!

@KapilArya  Thank you.  My laptop is an Acer Aspire A315-42 and was bought last year with Windows 11 inside,  Now I note that I can power my laptop  and work normally only if CTRL (or F1 also) key is pushed and maintened down : if I leave this key my laptop goes down immediately.    I am thinking that the problem maybe in the Keyboard itself.   To check this I will disinstall and reinstall the keyboard hoping that something positive happens.  If you want I can say you what happens,  Thank you very much.
