Verlauf von "My HP laptop shutting down itself" bearbeiten

Why is my HP laptop shutting down itself and wouldn't be put on again. Whenever it shutdown itself and I try to put it on again it won't. And it make takes hours if not days to be put on again. I even thought it was the battery until when I got a new good  battery to it and yet never stop shutting down.

Please help, I don't know what to do anymore.
