Screen turns black following a BIOS update.
Screen turns black following a BIOS update.
Your system runs on a Ryzen 5 2600 Galax B450M board, and the BIOS update worked but now you're seeing a black screen. It seems the update introduced compatibility issues with older BIOS versions. Clearing CMOS or removing the battery helped temporarily, suggesting a possible mismatch. You might want to try reinstalling the BIOS from the original source or consider upgrading to a motherboard that fully supports your current processor model.
No one else appears to have mentioned it, so I'll proceed. The choices are... upgrade or change your CPU to match your MOBO/BIOS version. Swap your motherboard to one that fits your 2000 series CPU. Make sure the BIOS is compatible or you'll face the same issue again. Restore your CPU if needed, then bring back the original model after updating the BIOS.
You experience the black screen during booting through the bootloader or after POST. If Windows is causing the issue, consider installing Clear Linux, Mageia, Nobara Project, Void Linux, or Artix Linux. Alternatively, try using a 'live CD/USB' to check if these OS support your BIOS+CPU setup.
