I have a Toshiba satellite - with windows 8. It occurred while trying to mirror the laptop to a tv (which I have done before) firstly it would not mirror and so I kept left clicking to enter resolution options and then all of a sudden it went blue. I was no longer able to do anything to this at all. I have tried turning off and on, taking battery out. I have read lots of other threads, but nothing really answers this. I can't open in safe mode as I can't even enter any commands. I have tried F8 F11 and all the other possible things I have read. It just looks at me with a blue screen and a cursor. Any help would be appreciated.
