Too late, but thanks. I decided to do a full reformat because frankly after 1 1/2 years there were enough scattered remnants of old programs, etc that it was the best way to get a new, clean system. With two hard drives it wasn't so bad. I backed up essential files plus put them on a CD. I just considered it spring cleaning. The computer is now as good as new. Which was my main goal. Now I just need to be more selective in what I add to the computer.
