Hi,
I have had my inspiron 14z for over a year and have never been successful in trying to enable switchable graphics. I have never actually been able to open Catalyst Control Center, even by trying to open CCC.exe as an administrator. I have gone through countless posts from people with similar problems but none of the solutions ever seem to work. I have updated my display drivers for both the Intel HD graphics (400) and my AMD Radeon HD 7570M cards, multiple times. I am not sure what else to do. Here is a picture from my device manager.
Any help would be appreciated, thanks.
