no signal from RX580

I am building a news system, and every individual component has been cross tested in some way. All of the components are in fact good.


However, when I install either a XTX RX580 or a Sapphire RX590, I get no signal from any of the ports. Both cards are confirmed to be working in another system.


When I install a GTX260 (Ancient nvidia card) the system boots fine and I get signal.


Something is mismatching between the mobo and the GPU is my assumption, but for the life of me I don;t know what.


The MOBO is a MSI B450M Bazooka Max Wifi. I had the identical problem on an GIGABYTE B450 I AORUS PRO WIFI AM4 AMD B450 SATA 6Gb/s USB 3.1 HDMI Mini ITX AMD Motherboard which I returned thinking it was the problem.


I have updated the BIOS on the MSI Bazooka, and installed windows using the ancient graphics card, as I read from some other sources that for some people the RX580 just didn't work until they booted into windows.



I am at a complete loss. This is by far the most frustrating PC build I've ever had.



Does anyone have any idea why new RX GPUs aren't working with these mobos?



My RX590 worked straight out the box with my 

GIGABYTE B450 AORUS PRO WIFI (AMD Ryzen AM4/ATX/M.2 Thermal Guard with Onboard WIFI/HDMI/DVI/USB 3.1 Gen 2/DDR4/Motherboard), so I thought the other B450 sockets would as well.
