i had sound problems with my toshiba satellite p50-b-117 so i send it to warranty. They changed my motherboard. Now my pc has AMD Radeon R9 m370x which is a GPU built for Mac. Because of that regular drivers gives the error code 43 and doesn't work. I also tried apple boot camp drivers but it didn't work either. I dont know what to do next. I cant use my amd GPU right now
