   Inlaw,

If you go open Device Manager, do you see hardware that lists as Other Decides or unknown? How about anything that has a yellow exclamation point?

I would try downloading the latest chipset for your motherboard, removing the currently installed chipset, and reinstalling the new (latest) chipset.

The download page for your motherboard is here: https://www.asrock.com/mb/AMD/B550M%20Pro4/index.asp#Download  I see there is an AMD Chipset package dated 9 March of this year.
