So last night my internet went out for a few hours and when it came back 4/5 of my amd rx480  rigs were mining at 0mh/s.  Windows 10 was popping up errors about how it prevent a program from using the graphic cards.  I assume this is a DAG issue.  But why would it happen after my internet went out? I tried to uninstall and reinstall 20.x amd drivers and pixel patch it with no fix.  Any tips?

Thanks
