Windows 10: Erratic Cursor

All of a sudden, my cursor has gone crazy. It will go into a continuous scroll pattern. It will print the letters in a word I enter...backwards. It will not stay where I put it. We purchased a new Mouse and that did nothing. We have done shutdown many times...power off. I found that if I hit ESC it stops...for one or two letters, then it is erratic again. Our former mouse was a logitechwired. The new one is a logi wired. We have re-connected everything several times. My son installed the new mouse and also re-installed the mouse driver.We have scanned twice for malware and threats

Surface Pro 3 - Erratic cursor and window behaviour

I experience intermittent erratic cursor behaviour on my Surface Pro 3. Any open windows also reduce in size and expand again. I keep the computer updated and have switched locations to avoid any external interference.

I've read various reports on Touchscreen drives and updates etc but nothing seems to cure this erratic behaviour. Any suggestions?

 

Dell Inspiron N5110 touchpad and cursor erratic

Hi, I am Junaid Qadir. I am facing a problem, When I start my Dell Inspiron N5110 laptop its cursor is a smooth and fine touchpad. For a time being its cursor moves erratic and jumps from one place to other places,
and finally, stop works. I am using window 8.1 pro with full updates. As I searched on internet lot of peoples suggested that updates BIOS, But actually I don't wanna update BIOS. Please suggest me some best methods. thanks
