This problem appeared recently. THere are certain keys on my keyboard that when I strike it either logs off, shuts down, goes into standby or something else. Also when I strike some of these keys another symbol appears. For example I will strike "y" and a "/y" appears. When I strike "Caps Lock" a "F" appears. When I strike "v" a "+v" appears. My question is will getting a new keyboard fix the problem or is it something else?
