我今年一直在经历这个问题。尝试找出原因并修复，但找不到任何好的解决方案，更新也没有帮助（BIOS 现在是最新的，操作系统是最新的，内核也是最新的之一）。尝试在 Google 上搜索这个问题，尝试解析 MCE，但无法从那里获得任何有用的信息。也许你可以给我一些关于如何修复这个问题的想法。
因此，我拥有的是：

这种重启非常频繁（每天一次），但电脑上没有任何负载，而且我在那里运行着一个媒体服务器和文件存储，这是不可接受的。

启用内存测试和交换后，以下是注释中询问的命令的结果：

Swap: 4.0Gi 0B 4.0Gi

您能否建议我应该从哪个方向寻找解决方案？
答案1
交换
您有一个交换问题。
total used free shared buff/cache available
Mem: 7.3Gi 1.2Gi 123Mi 15Mi 6.0Gi 5.8Gi
Swap: 0B 0B 0B
笔记：编辑您的问题并向我swapon -s展示cat /etc/fstab。
让我们确认/创建一个 4G /swapfile......
笔记：错误使用rm和dd命令可能会导致数据丢失。建议复制/粘贴。
在里面terminal...
sudo swapoff -a # turn off swap
sudo rm -i /swapfile # remove old /swapfile
sudo dd if=/dev/zero of=/swapfile bs=1M count=4096
sudo chmod 600 /swapfile # set proper file protections
sudo mkswap /swapfile # init /swapfile
sudo swapon /swapfile # turn on swap
free -h # confirm 8G RAM and 4G swap
sudo -H gedit /etc/fstab使用或编辑 /etc/fstab sudo pico /etc/fstab。
确认 /etc/fstab 中的此 /swapfile 行...并确认没有其他“交换”行...在此行中使用空格...确认没有制表符...
/swapfile none swap sw 0 0
reboot # reboot and verify operation
记忆
虽然你的数据没有表明主板的版本，但我怀疑你的主板是 1.x 版本。请参阅https://gigabyte.com/Motherboard/GA-A320M-H-rev-1x#kf如果您查看 CPU 和内存文档，您会发现您的 8G RAM Corsair 型号 # CMK8GX4M1D3000C16 似乎不在受支持列表中。请参阅https://download.gigabyte.com/FileList/Memory/mb_memory_ga-a320m-h_bristol.pdf
更新＃1：
去https://www.memtest86.com/并免费下载/运行它们memtest来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。这可能需要几个小时才能完成。
如果失败，将 DIMM 从插槽 DDR4_B1 移至插槽 DDR4_A1 并重新运行 memtest。
如果再次失败，请更换 DIMM。
