CPU from the 5000 line isn't responding even after BIOS update succeeded
You're asking if the issue lies with the CPU or the motherboard. Since you're using an AM4 board and want to avoid reinstalling your PC, consider checking the motherboard first before replacing the CPU.
The CPU seems to be the issue, which is what you were thinking might be causing the problem. Windows doesn't seem to cooperate with changing CPUs, so a reinstall wouldn't be needed unless you choose to try it. This step is optional if you prefer not to go through troubleshooting. It would help to figure out what's happening, especially if it works on another motherboard—it would definitely be a DOA. If it worked, then the problem must be elsewhere. You haven't mentioned before, but is the 5600x model new or used?
