black screen ASUS B550 Motherboard black screen issue

[Nerdis]

Hey guys,

 

I build myself a new PC with following specs:

 

Motherboard: ASUS TUF GAMING B550 PLUS

CPU: AMD Ryzen 7 5800X

GPU: ASUS Strix GTX 1060 6GB 

RAM: 4x8GB 3600MHz G.Skill

SSD: Samsung EVO 500GB NVMe

PSU: Corsair RM850

 

I updated the BIOS to Version 1401.

After that the PC bootet, I tried to install Windows but after the necessary reboot I won't get any video output. Not even BIOS. 

 

I tried HDMI, DisplayPort also my old ASUS Strix GTX 970 but nothing.

CMOS reset also didn’t helped.   

 

Debug LED also is useless. 

 

Do you have any idea? Googling and asking all my friends with ASUS Motherboards didn’t helped either.

Try bios flashback - https://www.asus.com/dk/Motherboards-Components/Motherboards/TUF-Gaming/TUF-GAMING-B550-PLUS/HelpDesk_BIOS/

Before running the USB BIOS Flashback tool, please rename the BIOS file (TGB550PS.CAP) - format usb drive to fat32 before putting bios on stick

@DoctorNick Was the first thing I've done because Ryzen 5th gen weren't supported with the included bios version. But I can try it again.

@DoctorNick It looks like it works. Thanks a lot. Do you know why it's behaving like that? Never had issues like that before.

I don't know. I have tried similar on my X470 Crosshair VII Hero. Was a bad flash.. Or something
