如果您面临随机关机或重启，请不要担心，因为有时Windows会重启或关闭 PC 以安装重要更新，防病毒软件(Antivirus)会这样做以保护您的系统免受病毒或恶意软件感染等。但如果随机关机或重启频繁那么这可能是一个问题。想象一下您的计算机每小时随机关闭，这是用户面临的一个非常烦人的问题。
大多数计算机设计为在系统温度达到 70 到 100摄氏度(Celsius)时自动关闭。换句话说，如果您的 PC 过热，那么这可能是随机关机的根本原因。但是这个问题不仅限于一个原因，计算机随机关闭的原因可能有多种。
为什么我的电脑在没有警告的情况下关闭？
您面临此问题的其他一些原因是电源故障 ( PSU )、硬件故障、UPS问题、病毒或恶意软件感染、系统文件可能已损坏等。无论如何(Anyway)，不要浪费任何时间让我们看看如何在下面列出的故障排除指南的帮助下修复计算机随机关闭。(Fix Computer Shuts Down Randomly)
如何修复计算机随机关闭(How to Fix Computer Shuts Down Randomly)
确保 创建一个还原点(create a restore point) 以防万一出现问题。
