如果您的Windows计算机在没有警告的情况下自动重新启动或重新启动，或者进入重新启动循环，这里有一些建议可以帮助您识别和解决问题。有几个原因可能导致这种情况发生。问题可能有！可能是某些硬件组件故障、过热、Windows 更新^{(Windows Update)}或停止错误^{(Stop Error)}。

电脑^(Computer)自动重启，没有警告

您必须确定您的问题，然后查看以下哪种情况适用于您。你会看到蓝屏^{(Blue Screen)}吗？你的电脑过热吗？最近更新了您的驱动程序？^(Driver)安装了一些Windows 更新^{(Windows Updates)}？一旦您确定了可能的原因，事情就会变得容易一些。

Windows 10 意外关闭并自动重启

Windows 10 计算机在没有警告的情况下自动、随机重启可能有多种原因：

1. 蓝屏^{(Blue Screen)}或停止错误^{(Stop Error)}后重新启动
2. 由于硬件故障而重新启动
3. 每次Windows 更新^{(Windows Update)}后重新启动
4. 导致重新启动的驱动程序问题
5. 恶意软件。

让我们检查这些场景中的每一个。

1]蓝屏^{(Blue Screen)}或停止错误^{(Stop Error)}后重新启动^(Reboot)

为防止软件或驱动程序问题在停止错误^{(Stop Error)}后重复重新启动计算机，请执行以下操作。您需要这样做，以便您可以阅读错误代码，这反过来可以帮助您解决问题。

使用Windows 10的^{(Windows 10)}WinX 菜单^{(WinX Menu)}，打开System . 接下来^(Next)单击高级^(Advanced)系统设置> Advanced选项卡> Startup和Recovery > Settings。

取消选中自动重启^{(Automatically restart)}框。单击应用/确定并退出。
