Recent glitch preventing me from logging on to my computer [View all]

Started last night. I had 5-6 windows open and the screen froze up. Kept trying to close windows and they’d just pop back open. The pop up in front of the rest was some kind of Microsoft thing that I didn’t recognize and hadn’t opened. I finally got a couple of the windows closed but couldn’t get the last couple closed and the annoying pop up started opening and closing and shifting up and down. I tried both hard and soft reboots but everything would just pop back up. It started happening faster and faster till finally the computer shut itself down.

I couldn’t log back in because the constant shifting interrupted me from entering my pin. I left it off overnight, same thing today. My son opined it sounded like a stuck key, which I agreed with. I wiped the keyboard down an blew it off with compressed air neither of which helped. I use a wireless mouse and changed the battery in that. I can use either the mouse or touch pad when the mouse is installed. Either one gave me the same results and when I try to enter my pin it comes and goes too quickly to log in. I noticed when I completely removed the mouse the touch pad quit working or at least that appears to be the case. Any ideas?
