Editor crash on using

Development Getting Started & Setup

Today my editor have crashed twice all of a sudden.
Firstly, the screen turns all black, and then the UE4 just crashs.

I don’t think that I have done any thing that may cause this problem.
It seems like both GPU related problem.

Here is my crash logs:
