Windows 10: Black screen entering bios, but windows run fine

Hi, I have an old PC and updated the bios with ASUS Suite, and now i cant access the bios holding down delete at startup. I can see the bios logo and windows run fine. When I try to enter the bios the monitor shows me a simple black screen and i cant do anything. I tried to clear cmos, updating the bios again, reinsert ram, disconnect sata cables, using a different monitor, but nothing seems to work.

Here is the configuration:
Windows 7 Pro
ASUS P9X79 LE
Intel i7 - 3820
Nvidia GeForce GT 630
2 x DDR3 4 GB A-DATA PC3-10700

Blank screen when entering BIOS, but Windows Boots fine on ASUS CH7

Hello,

I wanted to check the bios settings and I have suddenly found out, that when I press DEL to enter BIOS, the display is blank. Monitor is On, it has signal, but with blank black screen. Computer starts normally, beeps, displays the AMI initial screen and normally boots into Windows. If I press DEL however, instead of going to BIOS, I get blank screen.

Baseline:

• AMD Ryzen 2700X / ASUS Crosshair 7 WIFI
• BIOS 2008
• Windows 10 PRO 1809

Troubleshooting done:

• Monitor to any other display output (only this one is on, others are off)
• Different VGA
• BIOS reset - did not help, although it was reset. I got message that BIOS was reset, press F1 to enter bios, but then - the same issue.
• BIOS Flashback update - After pressing the button, it blinks 3 times, then turns on, which should be OK. BUt nothing is happening - the led on USB stick does not blink. Whan I interrupt, the PC works as before.
• EZ Update in Windows - after submitting to update the bios, it restarts, but then enters the BIOS, which is - blank. After restart, all works as before (with black BIOS)
• Entering BIOS from Windows (Shift-Restart) does have the same effect

I am out of ideas now - the PC works, just can't get into BIOS to change anything. Of course, now, I have the default settings loaded because of few BIOS resets.

Interesting is, that when in BIOS, I am getting 0d on the postcode - changes to this after entering the BIOS. In the manual, this value should be reserved for future AMI BIOS errors.

Any hints?
