I have Dell Inspiron 5737 with Radeon HD 8870M graphics card. After clean windows install, gpu gets detected correctly, but when I install Crimson drivers, my graphics card in device manager changes to mx200 series (or something similar). Then my laptop refuses to go to sleep (screen turns black, but laptop still on, keyboard backlit, fan working) and it will stay in this state until force shutdown. Gaming performance is terrible.
Could you please advise what to do to get ati drivers installed correctly?
(It worked ok before windows update few weeks ago, also on windows 8 and 8.1 before)
