Installed a new CPU, updated the BIOS, but now neither processor functions properly.
I have a configuration featuring a Ryzen 5 3400G and an ASUS Prime A320M-K motherboard. I recently acquired a new CPU, the Ryzen 7 5700X. Prior to installing it, I updated my BIOS as advised by various resources. After the update, I powered off the system and replaced the previous CPU with the Ryzen 7 5700X. When I restarted the computer, it booted but remained inactive and unreadable. I then reinstalled the old CPU (Ryzen 5 3400G), but that also failed. I attempted to fix things by re-seating RAM, resetting the CMOS battery, and following other standard troubleshooting steps. Eventually, I brought the PC to a repair facility, which advised against BIOS updates, stating they aren’t always secure. They explained that their A320M-K board functions correctly with another CPU (up to the 5600X) and confirmed both the Ryzen 7 5700X and Ryzen 5 3400G are compatible with different boards—but not with my updated board after the BIOS change. What might have occurred?
It functions on various components. I also verified that there are no bent pins.
They’re making mistakes. You definitely need to update your BIOS to fix both compatibility and security problems. The main drawback is that most updates will erase your custom configurations, though you can easily restore them. Your motherboard is compatible with "ASUS CrashFree BIOS 3," allowing you to re-flash the BIOS using a USB drive. Here’s a guide on recovering from a corrupted BIOS flash.
