[SOLVED] New PC build no signal

[Vodlex]

Hello!

So I built a new pc today and when I tried to boot it I got no signal on my monitor.
All the fans would spin, the LEDs on the case and the watercooler would turn on, even the lights on the plugged in keyboard turn on.
I triple checked all the cables connected to the motherboard and they all seem fine, my psu is a modular one so maybe one of the cables isn't plugged in right? I don't think this is the case tho
I'm still waiting for my gpu to arrive so I can fully complete the build, but I used my old rx 580 just to see if everything else works properly.
I tried resetting the CMOS, using only one stick of ram, using other ram slots, using different PCIe slots...
Specs: B550 Aorus elite v2, Ryzen 5 5600x, Trident Z 3600mhz 2x8gb, NZXT Kraken x62, Corsair RM750, Samsung evo 900 1tb, rx 580

The motherboard probably needs a BIOS update to run the 5600X. Did it say 'Ryzen 5000 or Ryzen 3000 ready'' on the box?

Your motherboard BIOS needs to be updated to F10 to run the 5600X. Luckily it supports BIOS Flash so you'll be able to download it onto a USB and update it that way.

On the site it said that it supports ryzen 5000 series, I ordered it off of ebay, it was brand new

It 'supports' the 5000 series yes, but many of the B550's still need the BIOS update. What does it say on the motherboards box?
