I have been puzzled on this one, my computer for the past few months has had a mind of it's own. It first started typing full and half sentences about two months ago, at first I thought it was a virus and took the easy way out and reformatted. I have two hard drives in this machine and I have formatted them both twice at least, loaded both xp home and ubuntu on them and still seem to get the mystery typing. I have even taken memory out , switched the order and changed out my g15 for a normal keyboard. I have yet to find a solution, somehow it keeps typing on its own, deleting characters , using the arrow keys to go back and forward on websites and pressing enter on it's own. I have used spybot, windows defender, and adware tagged up with norton 10.2 corporate edition. I have used two different online scanners and still no luck, does anyone know what else it could be? I don't have office or voice recognition nor do i have a microphone plugged in so we can safely rule that out.
