Why is my game doing this?

I recently bought a g815 keyboard and predator XB2 monitor and run them both off of my predator 17 laptop. All three ran fine and then about 3 days later its like someone was taking over my keyboard and just typing gibberish and so I ran malware bytes and avast boot scan and nothing. So I figured it's the tech? Its like it's just replaying old game commands on top of mine while I'm playing. I've tried unplugging both the monitor and keyboard but it continues to happen can you help?
