Acer R5-471T Touchscreen touching by itself.

Hi there. Just recently, my Acer R5-471T Laptop has been touching the screen all by itself, and when I try to do something, it just keeps on clicking in random places. The only way to stop it is to put the laptop to sleep, and then wake it up. But after 5 minutes, it starts clicking again.

I know this is a strange problem, but any input will help.

Thanks, Deakin.
