I put my new purchased Rog Strix RX580 to my Intel 4th gen mobo (MSI B85M E45), but it couldn't boot up. The leds, the fans worked, but no display on my monitor (monitor led stays orange) and i couldn't even reach BIOS screen. My motherboard supports UEFI, but i'm using Legacy boot. I also updated my BIOS to the latest version, but the problem still occured. Tried twice on other new mobos of my friends using UEFI boots (A320M and B450M), it booted up okay.
Is my mainboard not compatible with new graphics cards like RX 580? I don't really want to buy a new rig, because i will have to replace my CPU and RAMs as well and that is truly a pain.
