This was caused by a stuck page up button on a Logitech M570 wireless mouse.
I had same issue on a Windows 10 on a Lenovo W530 laptop using Logitech M570 mouse. I had tried many other suggestions on various sites and finally ended up on this solution to try. A switching mouse seems to have helped.
It was strange as along with Logitech Mouse, mousepad on the laptop also stops working. So never suspected a mouse causing the issue.
I had tried to update firmware on Logitech Mouse, but had not helped. Not sure what exactly is the issue with mouse, but swapping to another mouse seems to have resolved the issue. Will monitor for next few days.
