几天前，笔记本电脑无缘无故地关闭了。从那天起，它就无缘无故地随机崩溃了。
这是我（正确地？）从上次崩溃的日志文件中过滤出来的，但我不知道这意味着什么。当时有几个进程正在运行：chrome 和 firefox 上的许多网页、一台装有 WindowsXP 的虚拟机和 clamscan 服务。
问题的根本原因是什么？另外，你认为我必须激活该apport服务才能获取更多信息吗？

虽然前一个包含所有日志我认为与崩溃相关（检查时间戳），这些是完整日志的链接
事故发生11月4日 10:53:56（实际上，大约一小时前发生了另一次崩溃，但我不知道正确的时间戳，因为我当时不在笔记本电脑附近）。
奇怪的是：你有没有注意到，有一行的时间戳与前面的不一样？我的意思是这个

好吧，我再次尝试运行clamscan，这次只在我的home目录中运行。但是，在某个时候，核心温度超过了 98°C，所以我停止了该过程。我尝试clamscan再次以详细模式运行以查看特定文件是否有错误。在某个时候，核心温度超过了 90°C，但这次桌面关闭，然后计算机停止。另外，我有一段时间无法重新启动它（直到它再次冷却下来，我想）。所以，我认为问题与高核心温度有关。当然，clamscan我的笔记本电脑在 4 次上冻结了 3 次（唯一一次没有冻结是因为我手动强制停止该过程）。对于之前的崩溃，也许某个过程在某个时候开始使核心变暖；但是，我不知道是什么过程。FWIW，这些是针对事件崩溃时间过滤的日志文件。
系统日志 内核日志
这种strange模式再次出现。有什么建议吗？

尝试：
$ sudo service whoopsie restart
如果不起作用，请使用以下方法搜索错误：
systemctl | grep -i whoopsie
cat /var/log/syslog | grep -i error (or failure)
并向我们展示所出现的内容。
或者完全删除 whoopsie 包：
$ sudo apt-get purge whoopsie
whoopsie 包现在将从系统中删除。
