I have a big problem with my dual Graphics Card. I have a Hp Pavilion 17-e113sh Notebook. This Notebook has a "ATI Radeon HD7640G + 8670M" dual graphics card. But when I Installed windows 10 or 8.1, this got an error, and my laptop say I haven't graphics card. I saw it in dxdiag. I'm so frustrated, this notebook has a very good specification, and I love it. But I can't find key for this problem. I have photos, thank you very much.
Sometimes the Plug and Play Display disabled. Windows disable it.
