I recently reinstalled my windows 7. After that, my graphics drivers were - according to windows - up to date yet I cant start any Games and get errors suggesting that I dont have any graphics drivers installed. https://i.gyazo.com/1c185f2a019e6cf874818f2b62accc52.png
Now I already uninstalled my drivers and rebooted and that didnt help. I tried manually using drivers from my hard drive that I selected from the AMD homepage according to my graphics card type (R7 270x) and that didnt work either. I am a bit desperate and would appreciate help!
