The boot up issue likely means a system is running an early BIOS that does not have support for newer processors. This can be resolved by updating the motherboard BIOS to the latest version, which can be performed by using any processor supported with the currently installed BIOS. For a list of supported processors per BIOS version, please refer to the CPU Support List document available on the motherboard manufacturer's website. BIOS download and installation instructions are also found on their websites.In response to these reports, AMD uploaded a new support page with details and workarounds, you can check it out over here. AMD recommends asking the retailer for a BIOS update, or to try it yourself if you have access to a first-gen Ryzen CPU. Alternatively, AMD can provide a free-of-charge boot kit.
