My Computer Types Words?

I would try to plug in a different keyboard and see if it's a problem with your keyboard. Also, try going to your control panel and keyboard settings and put it all on default to see if that helps.

check your usb ports - has someone plugged a device in? if there is something there that there wasnt before someone may have plugged in something that types random letters.

also check if there is a gmote server running on your computer - someone could be using their smartphone to mess with you. (this should be shown with the logo on the toolbar)

if not, try another keyboard. it may be broken.

EDIT:

still try plugging in a usb keyboard.

check if anyone has downloaded any software that might do the same as the usb device.

get antivirus software (try AVG free) and run it. try things like malwarebytes anti-malware free as well.

I can see that it's got some sort of error. It's capitalizing the start of every word.
