我正在使用 Ubuntu 14.04。在运行程序时，Ubuntu 会自动关闭所有正在运行的程序并锁定系统。如何解决？请帮忙。
编辑：当我运行时tail -f /var/log/syslog，我看到了以下内容：

答案1
您遇到的问题可能是由于内存故障、硬盘坏道或 BIOS 相关问题造成的。因此，请检查系统日志和内核日志，以检查问题究竟是什么，并据此采取相应措施。
尾部-f / var / log / syslog
Note: gnome-system-log tool can be used if you are using gnome.
要检查内核消息 -消息（/var/log/kern.log）
