We cannot help you. Nobody can. Format your pc or contact gigabyte. That is the problem with drivers. Drivers are for all. Not for you exclusively. Harsh truth. As long as there are users with rx570 and downclock works, amd will not acknowledge you. The same thing happened before with older cards. Stop derailing the thread. It is not a driver bug. It is in hardware and os. Use search in forums, see this happens since gcn 1.0.
