quick question. Have you checked Event Viewer under Administrative Tools? specifically the System logs? Maybe that will give more info, and you can post back here.
Weiiiiirdd. In the system log there is nothing after 15:47:29 on 21/09/2015 even though i´m pretty sure it crashed around seven pm....
I booted into windows correctly at 9:10 on 22/09/2015
