Ack windows reinstalled already?
So off of your mobo manufacturer's support site, you'll get all the drivers you need except the gpu driver which you should get off of the manufacturer's site (amd in your case). BIOS you don't need to re-flash, you already did that.
Audio, LAN, USB, chipset, sata for sure. Not sure what utilities are but probably allow you control of fans, overclocking and so on, so I would. Bios-utilities shouldn't be necessary since you used ez-flash already. Hotfix not sure what that's about but maybe had issues saving windows key? Who knows. I probably would get that as well.
After that GPU drivers. Did you already install them? I would reboot into safe mode, uninstall using something like DDU, then reinstall latest version from amd's site (after you've done all the updates I previously mentioned for audio, chipset and so on).
What do you mean you deleted something from amd map? Not sure what that is? Was this before you reinstalled windows? How is this connected to bios?
I only know of updating bios forward, I don't think you can go back. Typically when they're released, they improve performance. If it had issues, it would have been pulled from the download page, and newer version released to fix it.
From what I can tell on cursory glance at that event log, it's a lot of error because you failed to install all the motherboard drivers you should. Go do that and see if it still happens. The amd one you mention might be cause of missing chipset drivers i think. Try installing.
