What should I do if the BIOS becomes corrupted or fails to load on the ROG Strix B450-F Gaming?

Use the ASUS CrashFree BIOS 3 utility, which is an auto recovery tool that restores the BIOS file automatically. Turn on the system and insert either the motherboard support DVD or a USB flash drive containing the BIOS file; the utility will automatically detect and read the BIOS file, then enter ASUS EZ Flash 3 automatically. It is recommended to press <F5> to load default BIOS values after recovery to ensure system compatibility and stability. Do not shut down or reset the system during the BIOS update process.
