The PC fails to start after installing the old CPU following the BIOS update.
I previously had an ITX build that was sitting idle. I thought incorporating my current setup into the ITX build would be a good idea for college. I followed that plan and installed a Ryzen 5 5600X alongside the Ryzen 5 1600 in the ITX configuration. After updating the BIOS, everything functioned smoothly. Now I’m reverting to the original ATX board and rebuilding the ITX with the 1600 chipset. However, when I try to boot with the 1600, the display fails to appear. In contrast, the 5600X works without issues. It seems the issue might be related to a BIOS version mismatch—possibly needing to revert to earlier BIOS versions. Let me know if you have any questions.
You likely won't be able to. This warning indicates irreversible changes. You might attempt to flash an older BIOS, though outcomes could vary. BIOS chips are constrained in size, so only certain models like 1000/2000 series are supported. Also, please share the motherboard model name.
