Un processeur inconnu détecté, une mise à jour du BIOS est nécessaire pour libérer tout son potentiel

Hello
I dismantled my computer to clean it (I did not remove the CPU or the heatsink) and when I turned it back on, a page appears with "unknown CPU detected, BIOS update is required to unleash its full" written on it, and then it shuts down after 15 seconds. I then went to check the forums, and I installed the latest BIOS version on a USB drive. But when I turn on the computer, I still see the same message and cannot access the BIOS.
Thank you in advance

    Hello,

    It says that there is a USB overcurrent detected.

    Disconnect the USB devices.

    It says CMOS Checksum BAD.

    You can perform a Clear CMOS.

    1. In principle, this involves disconnecting the power supply on the 230V side.

    2. Remove the CR2032 battery.

    3. Short-circuit two pins marked CLR_CMOS for about 10 seconds.

    Either use a jumper to temporarily move, or use a screwdriver.

    4. Stop short-circuiting.

    5. Reinsert the CR2032 battery.

    6. Reconnect the power supply.

    7. Start the computer.
