Please! RX 580 black screen on pre boot

Hey everyone, I really need help.

When I enable CSM in BIOS, computer powers on perfectly, boots clover, starts loading Mojave then loses signal on 75% apple logo. When I disable CSM, I lose signal on pre boot/clover screen, but screen comes up perfectly into macOS. CPU i7 4790K + GA-B85M-D3PH mobo.

Had a 1050 Ti, sold it and replaced with RX 580. Removed web drivers. I have dual boot so I really need to be able to select Windows on Clover screen. Any thoughts?
