If you want to sell your old computer there is one over-riding problem you have to solve - deleting the data on its hard drive. Sitting on that drive will be the sum total of your, and your family's, digital life. It will contain login names, passwords, sensitive documents, cherished pictures and every other sort of information. Any and all of that could prove valuable to hi-tech criminals who use that personal data to steal from you directly or tarnish your good name by using it to sign up for credit cards and the like.
