Right away i'll have to tell you blue screens are normally linked to hardware issues. It could be something simple like memory creeping out of the socket because of the heat or a dying GPU.

This would be where you ask the techie friend or sibling to check out your machine. Maybe run "sfc /scannow" in an administrator command prompt (win10 you rclick start). "Chkdsk /f /x" too possibly. That one slacks on the progress indicator for a while but it's still working though.
