I have a Dell Inspiron 15 - 3521,
Windows 8.1 (64bit). I have dual/switchable graphics offering 'Intel HD 4000' and 'AMD Hd 7640g' but somehow the graphic driver is not working for the AMD and I'm forced to use the Intel HD.
I've downloaded both the drivers from the original dell website for my laptop but whenever I install them both, the AMD one stops working. Even when I try to open the *Catalyst Control Center* shows a message that there are no settings that can be configured using it.
Please help, it's been more than a couple of years and clean installing and re-installing hasn't helped.
