The 0F appears to mean the Microcode is not loading. When I see Microcode, I think of firmware updates and updating the Microcode for the processor.

I have seen comments about the Microcode from other users but all I know is the Bios situation.

Does it make any difference if it is a restart or a cold boot?

The only way to restore the motherboard to work is to unplug the PC power supply from the mains.

When you do that, it normally requires the system to reboot and reset or re-read certain values, such as XMP.

You have basically the same system but I am not seeing your situation. I will research updating the processor's microcode.

You might check and see if you can reset Bios defaults or re-install the latest Bios update.

Thanks for the answer.

I have already the last bios version installed (1402), but I can try to install it again...

Before doing this, what is the procedure to perform a bios reset ?

There are procedures in the owner's manual for different situations. If your last Bios update installed normally there may be something else going on, such as a problem with the processor.

Try setting the Bios back to its default values and see if that changes anything you are seeing. We can only assume the error code is correct, but it may not be completely accurate or something else is causing the situation.

I looked at the microcode situation and it appears too complicated for me to suggest fixes.
