Windows 8 shuts down without a waing

After having a problem with Windows 10 that stopped the UI from working I wanted to restart my computer. But now I have a new error I had before that I had forgot about. It tus off without a waing. After a minute or two of being on my computer just dies. It will probably go away with time, but sooner or later my computer will die suddenly.

What should I do?
