Re: Computer died
Did he do his banking with software such as Microsoft Money or Quicken or something? If so, just install whatever software he used on another working machine and pull the database file from the old hard drive (you said you can still see all the data, correct?). Start whatever banking application and use File\Open (or something similar) to point to the data file. That should get you in unless it's password protected or encrypted or something.
But I'm trying, Ringo. I'm trying real hard... to be the Shepherd.
