事件查看器是“级别=严重，源=内核 - 电源，事件ID = 41，任务类别= 63”

当我玩传奇联盟时，我的计算机重新启动，但只有一些游戏...我查看查看器事件，我发现此错误：

Event Viewer is "Level = Critical, Source = Kernel-Power, Event ID = 41, Task Category = 63"

General:

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
