It can be done as a DIY. Wander thru YouTube and find your computer and you'll find many examples of what is needed... or go to your nearest middle school and there'll be a youngster that can do it in exchange for some pizza and soda (LOL). It is easy, view the tutorials and have the necessary tools standing by. -AND- While you have it opened, use a can of air and clean that nasty dust out of it.
