My windows 8 is black

I need help. The first time my apps, back ground and all the windows I open with google or netflix turned black I had to reinstall windows. That was last month. Last week again. So I refresh it this time. I still took time but not as much. Today again. As I was typing an email. Writing goes yellow or white and the window black.

Can any one tell me why it does that and how to prevent from happening.
Also is there an easier way to fix this?

Thanks
