Wasn't convinced that the amount of free storage space was the issue but it needed addressing as the last thing that you would have needed was Windows not booting up or the SSD failing on you.
This is looking like a hardware issue so first test I suggest is either trying a different screen on your computer or alternatively trying the present screen on another computer, a notebook that has the appropriate video port will do.
