Another potential solution:
Try doing a system restore to the time just before you started having problems.
The screen should show a list of any ‘new’ installs that could be affected.
After the system restore, you may need to reinstall those programs that showed up on the ‘affected’ list.

We’ve tried that , and got the message that it didn’t work with the error # . When we turn off that message the computer boots , as I mentioned in my thread .
