My computer run with windows 8.1, my graphic card is nvidia GT735M (intel desactivated for sketchup).

Update Graphics driver to latest from Nvidia.

Change search parameters, and click green search button:

Also Update touchscreen driver to latest.

Reboot, and see if new drivers helps.

Try disabling the touch screen, (and touchpad if you have one,) so only the mouse is the active pointing device.
