Everytime I close my lid, try to hirbernate my computer or try to shut it down it doesn't respond properly. When I open the lid again my pc won't turn on, it doesn't hibernate properly or shut off. It started when I "upgraded" my verson from w8.0 to w8.1. I read that it could be my graphic video driver, I updated it using the driver autodetect from AMD but nothing changed. My computer is a Dell Inspirion 15 (3537), on Device Manager > Display Adapters it says "AMD Radeon R9 M265X", but I believe that my graphic card is an AMD Radeon HD 8850M.
Should I change the driver installed by AMD, or the problem may be something else?
