Why is it because the computer keeps going down?

computer

I've been using it well until a few days ago, but suddenly The computer keeps going down and there's something on the blue screen. Why is that?

Do I have to leave it as?

It's because the window is unstable.
Try installing a new window.

Maybe it's because there's something wrong with the window.
Or maybe it's because there's something wrong with the hard disk.
Ask someone who knows the computer well to look at it.
