A self-solving solution such as a countermeasure that may be effective when the motherboard BIOS does not boot or the cursor remains lit in the upper left.

Actually, the instability was still going on,

What I found was

1. Remove the button battery for a few minutes and put it back in to clear the CMO.

2. Turn off DISABLED for all FAST BOOTs.

3. Even if the BIOS version is not up, it is better to download it again with the same version of the BIOS, then UPLOAD and update it, if the BIOS is infected with a computer virus.

I understand that, so it's a self-solve.
