Black screen when opening BIOS (but windows boots fine)

I decided to visit the BIOS for the first time in a while yesterday but for some reason it doesn't want to load up anymore.

My motherboard is the Asus ROG Strix x399-E
some other specs:
4 sticks of tridentz 3200mhz memory (new reset to 2133 after clearing cmos), 8GB per stick.
amd threadripper 1900x currently overclocked to 4.2ghz, the clock survived the cmos wike because I did it with ryzen master.

Windows boots fine if I do nothing. but when I press DEL or F2 to open bios like I usually do, or when I go through the shift+restart menu thing (forgot the name), the bios doesn't load and I just get a black screen. It stays on A0 qcode for a while, and then switches to 0d after a few seconds (which is an AMI reserved error code apparently). Though the screen is black, the monitor stays on.

I have tried clearing the CMOS but all that did is it removed my ram clock and there is no way for me to get it back now.

I tried doing USB Flashback, but that doesn't seem to work for me, so I guess another question is how so I get that to work:
I downloaded the new .cap file, put it onto a formatted fat32 8GB usb, renamed the file to X399E.CAP
When I shut down the computer, put the usb into the port marked "BIOS" at the back of the motherboard and hold the button, it starts flashing but then stays lit which means there was an error. what did I do wrong?
I also tried the same thing with a different usb which is 16gb.

And if Flashback is not a potential solution, is there any other way I can solve this?

And if this is probably not a potential solution, is there any other way to get the bios working?

So I managed to fix this, not sure how exactly this happened. I also managed to bios flashback, but that did not help at all.

I started pulling out parts one by one, first all but one of my RAM sticks, all peripherals except for mouse and keyboard, and at the end all my hard drives. When I took out the M.2 drive I had installed (which was also the last drive I had installed), suddenly bios decided to work.

After that I cleared the CMOS again just in case, and started plugging everything back in. When everything was in as normal, the bios still worked.

I have no idea what affected this, but if anyone has a similar problem, start by pulling out all your hard drives.
