Hello,
For a few days now, when I turn on my PC, I see the 3 phrases mentioned in the subject at the top left of the screen. To be able to use my computer, I have to cut the power and it works.
Can you please help me?
Best regards,

    Hello.

    Go into the BIOS and load the default settings.
    The way to open the BIOS depends on the brand and model of the PC.
    Then press the keys:
    F9 -> Enter
    F10 -> Enter

    Hello,
    Thank you for your response, but I don’t know how to access the BIOS. My PC is a LENOVO.
    Thank you

    It's a LENOVO IDEACENTRE 510-15 desktop computer.
    Microsoft restarted my PC and I came back to the error messages:
    1st page: Invalidation signature detected. Check secure
    Boot Policy in setup
    Secure boot violation OK
    2nd page: Checking Media Presence …
    Media present…
    Start PXE over IPv4
    I pressed escape twice and I got error code 1962.

    Restart the PC, when the Lenovo logo appears, press the F1 key
    In the BIOS, also disable Secureboot
