Specs:
5600x
Rx 580
MSI X570 a pro

Issue: I can boot into windows just fine but when I try to get into the bios, I get no video output.

What I've tried: I tried latest bios build (HC), most recent "supported" build (HB), resetting CMOS with jumper and changing the battery. Can get into BIOS on my 3600 just fine. Tried with hdmi and display port on different monitors. Removing all drives. Going back to latest bios. Removing wifi card. Trying just one ram, then two (I have four sticks). Upgrading chipset.

More info: I just upgraded from AMD 3600 to the 5600x. When booting for first time, I get boot error light and restart computer. Boots straight into windows. When I reset and try booting into bios or into boot selector, there's no video output (keyboard and mouse lights are on and no error lights on mobo). I also tried getting into bios from windows (shift+restart) method but same issue.

At a loss now
