Ok so, I have an Asus G73Sw (laptop) with a built-in keyboard (Only a couple months old.), and recently it goes insane. For example, suddenly while i'm typing the letters will stop. While i'm in a web browser, if I hit 'D', it will save the page i'm on as a bookmark. Other letters will do other things, and ESC will close the page i'm on. Sometimes if I mash and smash the keyboard it will start up again, but it didn't go up again this time and it caused me to restart my computer while installing Battlefield 3. Why is it doing that?
