I haven't seen this myself, but a Google search on the error message you've quoted brings a variety of possible causes. The most commonly reported "cure" seems to come from a scan of the system for malware. I suggest you Google the error message and look at the options it canvasses where others have encountered the problem.
Apparently you can disable the one minute shutdown timer thusly :
When you see the timer, go to Start/Run, and type in "shutdown -a" (without quotes) and hit enter. This should disable the timer.
That should give you a little more time to see what options you can work through.
Good luck
