HDMI not detected in laptop (GPU and audio)

I don't think reinstalling would fix it. I say this because I wouldn't have the same problem with the live session, which before all of this, it always worked. Right now the problem is monitor output, internal speakers and plugged in headphones. None of them work.

I also checked with another computer by using this same USB live and it works everything: cable, monitor and sound.

There is not a setting for HDMI in your BIOS/UEFI, is there? Some computers do have a setting which can enable the port.

No, I looked through all the BIOS and nothing says HDMI.

At least these errors no longer appear. But I wonder what could it be the real problem.

Now this is happening and it's overloading my CPU. I'm not doing anything. It has gone crazy.

I'm sorry, but I am out of ideas.

Thank you very much for your help! I really don't know where can I ask about it?

Is there an ASUS community forum? If so, someone there might be able to give more help regarding BIOS options and what happens when resetting it.
