Have you had instances when your computer wasn’t working right, but you were not sure why? I worked on a client’s computer today, where the keyboard would only work with select letters (try writing like THAT!). She wondered if it was worn out, being almost three years old. NO! That’s not too old. As it turned out, I was able to fix it by replacing the entire keyboard–a $13 part. While we were at it, I gave it a complete optimization. Now it works like new. Always ask me!
