Hello. I have an dell inspiron 3537 with an amd radeon 8850m and intel hd 4400 graphics. It worked fine until a few days ago, but suddenly it doesn`t recognize my gpu anymore ( in device manager it only shows my hd 4400). Tried reinstalling legacy drivers, tried with the new crimson, tried reinstalling windows without any success ( when i try installing the crimson autodetect i get error 173). Any possible solutions to this ? Thanks in advance .
