I have an acer e 15 e5 574g laptop which came with windows 10. Due to some issues I installed back windows 7 without any back up. to my surprise there are no drivers for windows 7 for the laptop. I some managed to install the ethernet and wireless lan drivers as some of the other latops had similar architecture . The problem is no usb port works and there are no drivers which are compatible with windows 7 Can anyone help me in this case ?
