Windows 10: Cursor is jumpy

Why does my cursor erroneously move around AND highlight full sentences AND/OR paragraphs AND then delete them if I hit the spacebar (at least I THINK that's when it happens) when I am typing? Very annoying. I will be typing and look up only to see that I'm typing wherever the cursor decided to jump to causing my message to be a jumbled mess. Now, as I type in Microsoft's software (Bing and Edge), the problem rarely happens(but it is happening a little). I use Chrome as my browser. Is this Microsoft's way of sabotaging all that isn't Windows?? Please tell me how to make it stop. It shouldn't take 5 minutes to type a one or two sentence comment on Facebook.

cursor dissappeared

Thank you both for your prompt replies, I tried all steps listed, some I had tries previously but I still tried them again, but still no cursor.

Do you have any other suggestions?

 

Jumpiness with cursor and software responses after Windows 10 upgrade

I have upgraded to Win 10 on a Lenovo G580 laptop and wondering how to stop the random jumpiness of the responses (moving to different excel cells, opening multiple new message windows and etc.) Have tried a full reset ( very frustrating as I must reinstall
multiple programs). Still to no avail. Any suggestions?
