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

Restart the PC from the menu while pressing SHIFT. That will give you a menu where you can probably restart directly into your BIOS. If that doesn´t work it seems something might have gone wrong while flashing.

I used F8 because holding shift doesnt work. In the menu I selected Boot Setup or something like that, but the result is the same.

Is it possible for you to flash the previous version of BIOS again? ( downloading from ASUS support page or the backup copy you must have made already before update)
