My laptop is a Lenova 500G and it has one integrated graphics Intel(R) HD 4000 Graphics and discrete AMD 8750 HD, installed the driver on Intel from the official site, all is well-no problems, then installed the last driver amd http://support.amd.com/ru-ru/download/mobile?os=Windows 8 - 64 but in Manager, he defined as AMD Radeon HD 8600/8700M and writes Windows has stopped this device because it has reported problems. (Code 43). So the question is what kind of driver you want to install to make it work, and switched between the video cards?
