I have a few years old Iaptop I rarely use which, as I just found out has a Radeon HD 7670 card inside. I have to use this laptop for a while and I wanna play some games, but for some reason the integrated intel HD 4000 card is in use. I installed the 15.2 amd driver(I could not install the latest 15.7) but the catalyst center cannot start, even if I disable or remove the integrated card from the system(from device manager). How can I resolve this issue?
