Hi
@Tomo
When booting up, press the DEL key repeatedly to access the bios, if the bios interface will restart, please press the following operation to restore.
When the power is off, open the back cover, unplug the RTC battery, and use metal tweezers to short the two pins of the RTC port on the motherboard for 20 seconds to clear the CMOS
If the BIOS interface will not restart, please reinstall the system to solve
