我在尝试理解为什么我的系统随机停止或重新启动时遇到问题。以下是我的系统的规格，使用 neofetch 检索：

我正在使用这台机器通过 TensorFlow 运行 ML 算法。不过，我一直在监视 CPU 和 GPU 的温度，系统似乎并没有因为达到临界温度而停止。需要考虑的一件事是我的系统没有升级到最新版本（我已经使用了抓住命令来阻止我的内核升级），因为我的新内核版本和我的代码版本之间不兼容。
我已经看过了系统日志上次意外重启的时间，这是我发现的：

我很难理解所有日志，但从我所看到的来看，这似乎是这个过程SDDM崩溃然后系统重新启动我的系统。在其他情况下，我的计算机不会重新启动，而是不完全关闭。我的意思是我的屏幕没有信号，但我的电脑仍然打开（灯、CPU 等都打开），就好像它没有完成关闭一样。因此，我不知道是否SDDM崩溃是导致所有重新启动、关闭或没有任何重新启动、关闭的原因。另一个可能的原因可能是小规模停电，但在这种情况下我不知道我的计算机是否会完全关闭。
