When I turned off my computer on the 31 March (complete shutdown including mains switch) it was working fine.
When I tried to start it the next day it would not go beyond the grey screen. I did a restart using the power button and this time it progressed to the blue screen but no further. I pressed the restart again and it went straight into the signing on screen.
Needless to say I have not done a complete shutdown since for fear of not being able to restart it.
I have taken a copy of the system log covering that period. It means nothing to me - can anyone interpret the fault from it?
