Problem with PC failing to boot after BIOS update.
Problem with PC failing to boot after BIOS update.
The latest BIOS isn't designed for that old CPU. Your motherboard should allow you to revert to an older BIOS version, though finding the details might require some research. If you don't have it, you may need to purchase a new board from the manufacturer. Hope this assists! Let me know.
On the B450 Aorus M, locate the delete button on the rear panel.
Nope, if the CPU support was removed with this BIOS version there is no way to POST or get into BIOS without a newer CPU. That board does not feature USB flashback either. The funny thing is that the board does have dual BIOS chips but no physical dip switches to manually switch to the backup BIOS. The only way to do so would be power it on, hold power button for 10 sec until it turns off, repeat 3 times, it should boot to backup BIOS_B chip then. If that doesn't work, only option is to buy or borrow a Ryzen 3000 or 5000 chip and use that to POST and downgrade or just keep the chip. My advice, buy a 5600X. They are super cheap at the moment.
