我的笔记本在进行电脑游戏（巫师三）时突然黑屏，并不是关机，而是类似于按下熄屏键，然后五到八秒后会再次亮屏，输入PIN后发现游戏仍在运行。请问这是什么情况，如何解决？
如果有描述不清的地方可以给我发邮件。
My laptop suddenly went black when playing a computer game (The Witcher III), it wasn't a shutdown, it was similar to pressing the screen off button, and then the screen would turn on again after five to eight seconds, and after entering the PIN, I found that the game was still running. What is the situation and how to fix it?
