我的 Ubuntu 18.04.4 LTS 以前运行良好，但最近它开始随机挂起。之后发生了什么？一开始我可以再次登录，一切都没有变化。现在，它基本上重新启动了。我收到一条消息（消息的图片可以在下面找到），它要么卡住了，要么我可以登录（但它重新启动了）。这种情况变得越来越频繁，甚至每 5 分钟一次。我该怎么办？我从设置 → 电源中删除了挂起选项，但没有改善。
这是我暂停后收到的消息：
输出dmesg（如果有任何帮助的话）：

我之前的笔记本电脑也有类似的问题。它会随机自行重启。
在网上搜索后，我发现了许多可能的原因：RAM 故障、GPU 过热、CPU 过热、磁盘故障、主板故障。所以，是的，可能是任何原因。
但是，您可以尝试通过消除法来解决问题：
- 首先，检查磁盘是否故障。尝试使用另一块磁盘或 Linux Live USB 驱动器来连接笔记本电脑。如果再次发生这种情况，则不是磁盘问题。
- 第二，检查内存是否有故障。搜索有关使用
memtestBIOS 测试内存的信息。如果内存有故障，则需要更换它。 - 检查关机是否由 CPU 过热引起。请参阅此答案：https://unix.stackexchange.com/a/502794/162050。如果是这样，请拆开您的笔记本电脑，检查是否有灰尘堵塞风扇的通风口。您也可以尝试更换 CPU 和 GPU 上的导热膏。在某些笔记本电脑中，GPU 有导热垫而不是导热膏。在这种情况下，请不要移除该垫子。
如果这些方法都不能解决问题，你应该把它交给专业维修技术人员。
说到我那台有类似问题的旧笔记本电脑，有一天它突然死机了。打开它时，它会在黑屏上显示一些随机的乱码文本，并且会一直挂在那里。
我的建议是尽快备份您的数据，因为这种突然关机可能会损坏您的整个磁盘。把它交给专业的维修技术人员。开始寻找一台新笔记本电脑可能是个好主意。
