After upgrading to Win 10, 1603 display driver was unable to be instaled: in some moment notebook doesn`t responce to any command. To bring notebook back to life is to start Windows in safe mode and uninstal driver using DDU. I tried almost everyyhing: instaled previous Win 1507, previous driver version, a few days ago instaled new Win 1709 and new driver version, but result always the same. In addition, after installation Win 1709 my videocard was shown in task manger, but worked in low frequency. How to fix that problem???
