I have Dell 5521 15R Inspiron with AMD 8730M and Intel HD 4000. When I run to AMD Catalyst Center to setup, it shows an error that says Application Install: Install Package Failure. I tried to install GPU-Z to find if I wrong on my graphic card but GPU-Z program show nothing but Intel HD 4000. I've tried to start this graphic card since last week but it never shows itself. On my BIOS there isn't any option that says Switchable Graphic Cards. And I still think it's a software problem not hardware. And one more thing, I installed and tried lots of driver to see if I'm wrong but it never appears. What should I do? Please help me 'cause I spent lots of money to buy this computer and can't play any game.
