我有一台戴尔 G7 15 7590 笔记本电脑。我最近安装了 Ubuntu 20.04。
现在电脑每天都会死机一到两次。有时候电脑会死机，有时候我觉得需要完全重启。
cat /var/log/syslog显示：

每次冻结时，都会出现类似的消息/var/log/syslog
也许这与 wifi 有某种关系？
我尝试了这里面的所有建议Ubuntu 17.04 中的 CPU 硬件错误但什么也没起作用。
我看到有人提出了其他问题在 Launchpad 上和Arch Linux 论坛
这台笔记本电脑在运行 Windows 时没有问题，而且是全新的，所以我不认为这是导热膏或硬件的问题。
我几乎一直在运行 Chrome 浏览器，但它似乎与任何特定任务（即 CPU 密集型任务或 GPU 密集型任务）都没有关系，而且当我没有运行 Chrome 时也会发生这种情况。
有人能给我一些建议吗？
我尝试使用 nVidia 440 驱动程序和 Nouveau 驱动程序运行此程序，两种情况下都会发生这种情况。
