Upgrade your Ryzen 5 processor to the Ryzen 7 5800X model.
Your ASUS B450-F motherboard was designed for a different CPU model. After resetting the BIOS, it seems the new CPU isn't recognized or functioning properly. You should verify compatibility with your motherboard's specifications before proceeding.
Also consider verifying the VRM capacity on that board to ensure it can support the new chip. B450 typically handles this well, but if your new component consumes significantly more power than the previous one, the VRM may struggle and could fail. Your motherboard tier is listed as E on the tierlist, which might be a bit uncertain.
