At my wits end with this shit. Recently bought a Ryzen 5 5600X to replace my old Ryzen 5 1600. I put the new cpu in my ASrock ab350 pro4, but when I press the power button I get absolutely zero response from my rig. When I swap the old 1600 in, everything works like it did before. I know it's an old mobo, but the bios I'm running (L8.02) and the one I ran the first time I tried the new cpu (P7.40) both explicitly state they support the 5000 series. Any ideas what the issue is?
