Your pictures show that you have an enabled Serial port (SuperIO) and they have been seen to cause problems with 100 series boards. You should disable it in your BIOS settings.
It may or may not help you but you're not going to use it anyway so you might as well disable it.

You don't have nv_disable=1. Type -v nv_disable=1 in boot args. Note you don't need to type boot in boot args.

I see no such setting.

I see no such setting.

It is in your manual on page 32/33 :

Peripherals - Super IO Configuration

Dunno how you knew that, but it worked. TY
Installing now...

Update: OK!!! It booted up all nice and pretty. I installed NVidia Web Driver. Reboot. The change stuck. Everything seems good except the DVI monitor is working and the HDMI is "no input". I ran Multibeast and tried to install clover v2.3 and it said installation complete but a reboot showed the system still using the old (black background) clover.

Additionally, I'm still experiencing a bug whereby when I click "shut down" the system actually reboots and I experience something akin to a "vertical blinds" PPT transition every time I boot up.

I have done this, with still no success. I lost Clover v2 and can't reinstall it. Is there a report I can show you that would give you more info?

How did you create you're Boot stick? Unibeast or Createinstallmedia?

Unibeast. I'm not aware of the latter.
