I was playing dota 2 on my ASUS laptop and after closing the game, keyboard was not working properly. Number 3 key not working, when pressing `alt` it types `z` etc. I really don`t know what I could`ve pressed. Backspace also not working. I`ve tried turning num lock on and off, holding ctrl+shift and other combinations with on-screen keyboard, because I don`t know how my actual keyboard works now. What could have triggered this and how to get back normal keyboard? Also few keys turn on ASUS DVD menu screen and other built in ASUS programs. I`m getting really desperate, because nothing helps. I have windows 10.
