The reason you can't find software to do it is because there is enough people out there who know how to fix these buggers a lot quicker. Having replacement parts on hand helps but after you seen a few hundred computers not boot(amoung other problems) you start to get the feel for it and software (espiecially in this context) will never be as good as experience. It helps to get this experience on your own machines. I've been fixing computers for close to seven years now and I've never even looked for this kind of software.
