Unfortunately, short of taking the board to an expert and having the BIOS ROM
chip removed and reflashed, the only option is either a new CPU that is compatible
with the new BIOS or a new motherboard.

This is why I recommend people don't update their BIOS unless they actually need to.
To support a CPU upgrade, to fix an issue that the new BIOS is meant to resolve
or a critical security update. Otherwise, if the system is working well, leave it
be.]]> Sat, 25 Feb 2023 01:53:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=25522&PID=103654&title=srock-a320mhdv-r3-ko-after-update-bios#103654 https://forum.asrock.com/forum_posts.asp?TID=25522&PID=103649&title=srock-a320mhdv-r3-ko-after-update-bios#103649 Author: MistizioFriend

Oh no, the bios update removed support for your CPU.

*This BIOS doesn't support Bristol Ridge CPU, do NOT update this BIOS if Bristol Ridge CPU is being used. **It requires to update BIOS to 7.00 before updating this version. *** User will not able to flash previous BIOS once upgrading to this BIOS version.

You will need to upgrade your CPU to a Ryzen CPU.

The processor is an AMD A series A10-9700.
I have already tried resetting it via jumper (clearing CMOS) and by removing the battery, but it still isn't working.
Versions 7 and 7.4 of the BIOS supported the same processors, and the PC started correctly with version 7.]]> Thu, 23 Feb 2023 20:31:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=25522&PID=103624&title=srock-a320mhdv-r3-ko-after-update-bios#103624 https://forum.asrock.com/forum_posts.asp?TID=25522&PID=103622&title=srock-a320mhdv-r3-ko-after-update-bios#103622 Author: MistizioFriend

This morning I wanted to update the BIOS. The installed version was 3.6 and the latest version was 7.4. The version after 3.6 was 7, and in order to install 7.4 it was necessary to first install 7 as requested by the manufacturer. Once version 7 was installed, there were no problems and the PC started correctly. During the installation of version 7.4, there were no problems either, but now the PC won't start. Only the fans turn on and there is no power even to the USB ports. It's dead. Is there a solution? Thank you.]]> Thu, 23 Feb 2023 17:55:27 +0000 https://forum.asrock.com/forum_posts.asp?TID=25522&PID=103622&title=srock-a320mhdv-r3-ko-after-update-bios#103622
