I am running a Windows 7 computer. All of a sudden I've started getting the attached error message that hangs the computer on shut down and boot up. I checked my MSCONFIG startup to see if anything new is trying to load, but nothing seems to have changed. Can you please explain where this came from, if it represents a problem, and how to get rid of it? I haven't noticed any changes to the function of the computer other than at boot up and shut down.
