So what happens if your motherboard is fried by a power supply failure 
which was my fear yesterday? I thought that the disk drives would 
probably be OK but I knew that I could not find an exact replacement for 
  the motherboard and I feared that I would need to do a complete 
reinstall of the OS. I was not confidant that a reinstall could preserve 
the existing data. I also needed to provide a TV set to watch tonight's 
TV programs.
