About a week ago my keyboard started acting up. So I ordered a new one and replaced it. This did not solve the problem. The touchpad will work but the keyboard is still messed up. If I plug in a keyboard to the usb it will work fine. Also when I boot up the volume controls start acting up and will make a loud beep until I hit the mute button. If I don't hit the mute button then it will go straight into setup. Any ideas?
