Ok from what I have noticed your machine is freezing and you have to force it to shut off. Now the information I need is does it do this all the time or sometimes?
OK there is a way to set it back 2 weeks before the problem started. Do this, I am sending you a video on how to set it back to a time before the problem started try this first if it fails we will go from there. http://www.youtube.com/watch?v=oGXbMyFaROw
