Retired from another industry several years ago.  Had done IT work & computer repair part time over the years. Opened a one man computer repair shop to supplement retirement income in May 2012.  Thus far, very successful!  No complaints, but it's always good to have other resources to access when needed.  This is one of those.
I have 32 years experience working with and on computer systems from the early DOS systems to current ones.  Took some formal training years ago and have kept fairly current with the advances in IT.
