Also, do cnt-alt-del and click on task manager.
Click on Start and check for any odd craplets running. Disable them by right mouse click.
You also may want to look through your running programs and see if there is any malware running. Malwarebytes is your friend.
There is also a troubleshooter somewhere in the settings. I am not near my Windows10 computer right now, or, I would find it for you.
