Welcome to the forums.
First up the windows update is not the most reliable method to update the BIOS but if it completed successfully then lets move on.
When you updated, did you restore factory defaults first? With AM4 boards in particular this is a very important step.
Regardless of the procedure you followed lets see what we can do to get you up and running again.
The only thing you can really do at this point is perform a full CMOS clear:

If there are conflicting settings between the old and new BIOS revisions this should clear them. Let us know how it goes.
