|  I had the problem, too.
 My computer just recently had that same problem, and I tried the same techniques you used.  Then, my AVG anti-virus program got an update and said that there was a problem on my computer.  I healed it and haven't had any problems since.  However, at startup, a popup message now appears from contra virus saying "File config.ini doesn't exist.  Please reinstall software."  If your friend's computer doesn't have AVG, download the free version (that's what I have), and it should help.
