[Philmorr]

After trying to boot my system with a Ryzen 7 5800X and Ryzen 7 1700 which both didn't work.
The system finaly bootet with an Ryzen 5 3500 but now i am stuck at the Asus screen and can't enter the Bios..
and i don't have any other CPU to try on this board...
Aditional info of my system:
NZXT AIO
WD_Black SN850 1Tb M.2 Nvme
RAM = 1x16Gb Dominator RGB (Testet on other system = works)
GPU = RTX 2070 Super (Testet on other system = works)
i have tryed two Keyboards on all USB ports in case of an input error but the RGB of the Keyboards work so i don't know...
I tryed to flash the bios, didn't work either.
Only Boot Q-LED is glowing green.

The Ryzen 7 1700 is not supported on that motherboard.

For the Ryzen 5 3500 to work the BIOS version should be 0602 or higher.
For the Ryzen 7 5800X to work the BIOS version should be 2606 or higher.

Do you know the BIOS version?

The Ryzen 5 3500 CPU might be the only one that might work until you perform a BIOS update.
Try resetting the motherboard by removing the CMOS battery

-Turn OFF the computer and unplug the power cord.
-Press the power button several time to discharge any residual power from motherboard capacitors.
-Remove the CMOS battery from the motherboard and wait 5 minutes to re-install it back.
-Make sure the RAM is the appropriate slot (DIMM_A2), 4th slot from CPU
-Remove the NVMe drive.
-Place back the CMOS battery.
-Plug the power cord and turn ON the computer. It might take several minutes for the system to get into the BIOS.

Let us know how it went.
