I installed Lightroom 5 this past Sunday and it was crashing all week long but now my laptop will not restart at all. Is there a fix for that? I am certain that it is related because I was not having any issues with my laptop before I installed Lightroom 5.
An application cannot crash the entire machine, nor harm the hardware - especially not in a way that would prevent the machine from booting.
Only a low level driver bug, OS bug, or hardware defect could do that.
