It sounds like you could have some damaged windows files then. Are you able to use your keyboard before your startup to go into safe mode or choose the last known good configuration? Do you have any extra keyboards or mouses that you can test at the back to make sure that it isn't the computer, or the mouse/keyboard themselves?
