Lots of good ideas here and Molly's work around did work just as described.
Since I will not let a PC problem beat me I kept working and found the following
I could boot into safe mode with networking with no problems.
I noticed that Microsoft updates had not been done for some time but others had.
I downloaded all available updates from Microsoft including Service Packs then
booted using Molly's Control/Alt/Delete work around.
I disabled all processes one at a time until I found the program that was causing the problem
which turned out to be and Adobe Reader update. Since this update was installed on a system
that was not up to date it caused the system to hang during the boot up process. Once removed
it worked perfectly.
I un-installed then re-installed Adobe Reader and the problem is gone.
Hope this helps someone in the future.
