I have a Hp probook 450G1 with amd HD8750M using win 10. After i updated to the latest version, window stuck at the welcome screen. Then I used window repair and it deleted the driver of AMD. I tried to install many version of AMD driver (from Catalyst to Crimson), however, it can only install the AMD install manager (take only 20s to complete). And after that, seem like nothing happened. In device manager, it shows only intel graphic driver. I have tried to uninstall both intel and amd drivers but did not work. I really need some help. Thanks in advance.
