BIOS Gone Wrong After update. Dead PC?

[thefourCraft]

I did a normal BIOS update. It completed successfully.

But then the normal restart after BIOS installation never happened the PC went into a black screen. How can I fix this?

• BIOS Version: 3211 2021/08/26
• Motherboard: PRIME-B450M-A-ASUS-3211

The PC is under one year old, and all other BIOS updates went fine and had no such problem.

• The power (to the PC) wasn’t interrupted during the update.
• No overclocking or any modifications to the BIOS.
• USB is FAT32, and was only with the file provided By ASUS.(like always)

What I tried to do to fix this.

1. Unplug. Wait. Plug it back in again.
2. Reset the CMOS battery.
3. Check the RAM.
4. Use a recovery USB flash drive as explained here on the official ASUS site.

What can I do? Did I miss something? Is the motherboard dead?
