you need to use the Catalyst Install Manager, uninstall all AMD drivers & reinstall, you can attempt just a Repair but it probably will not work .. the typical Windows update headache that overrides AMD dedicated drivers with its own so called recommended crap
I have the same problem, win 10, running claymore dual ethereum... radeon r5 m335
I tried uninstalling, deleting and reinstalling drivers, no change.
Could be a problem with claymore. Annoying, can't find any fixes.
