Sometimes the screen will click crazy because the touch screen "thinks" something is touching it. In order to continue using the laptop, you can turn off the touch feature of the laptop.
In the search box on the taskbar, typeDevice Manager, then selectDevice Manager.
Select the arrow next toHuman Interface Devicesand then selectHID-compliant touch screen. (There may be more than one listed.)
Select theActiontab at the top of the window. SelectDisable device orEnable device, and thenconfirm. If there's more than one HID-compliant touchscreen device listed, perform steps 2–3 for that one too.
