Display works after BIOS hard reset. Then it goes blank when rebooted.

Problem description:

The machine started acting weird / glitching out. After initiating a reboot, the display was completely blank.

Specs:

Core i7-9700k Asus Strix Z390-E mobo G.Skill 2x16GB 3200 RTX 2070 Super 970 evo 1TB Seasonic 750w PSU

Troubleshooting steps already taken:

I went to minimum config. Since this has onboard graphics, that means CPU, SSD, 1 stick of ram. The PC turns on, but there is absolutely no display and no blinking or solid error lights on the motherboard.

I then removed the CMOS battery for awhile to do a hard reset on the BIOS. After putting the battery back in and turning on the power, it cycled on and off a few times to reset everything to default, and then POSTed, noting that the system configuration has changed. After going into setup, I simply hit "Save and restart". Then the computer does exactly as before, black screen with no other indication.
