I got a message that new hardware was added and I did not add any. At the same time, my desktop screen lost 4-1/2 inches from the side. What has happened and how do I correct it? It wasn't a wizard that came up stating new hardware was added, just a message. Thank you for your time.
look in the event viewer [admin events] and see if or what error is showen when that came up. if it was just a one time thing it just may be a driver the hung when windows was booting and recovered [or not]..
