Lots of forum maintenance may have buried your orig. post.
Anyway, there are no newer drivers for 6xxx and earlier cards (there's a last beta 16.2.1). go to driver download page, manually install(full vers.,not min.setup or auto install) either the catalyst 15.7.1, or the beta radeon 16.2.1(might be an idea to clean uninstall(use DDU to remove any old leftovers)
If that fails then please supply INFORMATION REQUIRED WHEN POSTING A QUESTION
May also be an issue of Win 10 over riding update ?
