PC won't display anything

[Stifter]

Hello!

I just build my first real custom PC but now i cant get into the BIOS or do anything really.

The only clue I guess I have is that on my Rog Strix B550-A there are the QLEDS lighting up. But not all the time, they go on and off in order and stay lit for 2 seconds.

Everything's connected and my GPU also works inside another PC.

 

Speclist:

B550- A Rog Strix

Rzyen 7 5800x

GTX 1080ti

NZXT z73

Corsair Vengeance RGB Pro 2x8 GB 3600mhz

 

i really need help with this build. Kind regards.

 

 

Update 1:

Tried reinstalling the BIOS but didnt change anything.

You will need to use the BIOS flashback and update your BIOS. B550 boards dont support 5000 series CPUs without a BIOS update. Consult the owners manual on how to perform the BIOS flash using the rear IO of your motherboard.
