Ubuntu 17.04中的CPU硬件错误

有人可以向我解释当我查看dmesg时得到的这些错误消息吗？我是Ubuntu和Linux World的新手。

CPU过热，进入MCE（机器检查事件）...即：它崩溃了。如果您在syslog中没有看到其他与温度相关的事件，则可能是因为您的CPU冷却器/风扇/热管/导热膏没有起作用。

• 使用此terminal命令检查系统日志...

  grep -i -e temp -e therm /var/log/syslog*
  

• 如果机器很脏/很脏，则可能在机器过热中起主要作用。清理干净。

• 如果您的计算机装有Intel处理器，请确保intel-microcode已安装。

  sudo apt-get update
  sudo apt-get install intel-microcode
  reboot
  

• thermald尝试安装并控制温度。

  sudo apt-get update
  sudo apt-get install thermald
  reboot
  

• 检查您的BIOS版本。开机时输入BIOS，并记下版本号。带有计算机品牌/型号的制造商的网站。转到支持/下载部分，查看是否有更新的BIOS。

• 最后，很有可能，如果这是一台较旧的机器，则需要重新应用位于处理器与其热管/风扇冷却器之间的导热胶。这需要一些技术经验。
