Why bother? Toss the computer unless you think there is financial information that is not in the will. Take the hard drive out and send or take it to a data recovery business and see if they can do anything with it.
Well, for one thing, this machine would make the basis of a very nice computer-sourced 7.1 surround sound system. And, yes, there is a VERY good chance there is some of my brother’s financial info on it. Granted, I should be able to plug the HD into another tower I have, as a 2nd HD, to view it, IF this machine is actually a Windows machine.
