Errores de hardware de la CPU en Ubuntu 17.04

¿Alguien puede explicarme qué mensajes de error recibí cuando busqué en dmesg? Soy nuevo en Ubuntu y en el mundo de Linux.

Estoy ejecutando Ubuntu 17.04 con 4.10.0-29-kernal genérico

La CPU se está sobrecalentando y entra en MCE (eventos de verificación de la máquina) ... es decir, se está bloqueando. Si no ve otros eventos relacionados con la temperatura en syslog, probablemente sea porque su enfriador de CPU / ventilador / tubería térmica / pasta térmica no está haciendo el trabajo.

• Compruebe syslog con este terminalcomando ...

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

• Si la máquina está muy sucia / polvorienta, eso podría desempeñar un papel importante en el sobrecalentamiento de la máquina. Limpiarlo

• Si su máquina tiene procesadores Intel, asegúrese de que intel-microcodeesté instalada.

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

• Instalar thermaldpara probar y controlar la temperatura.

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

• Verifique la versión de su BIOS. Ingrese su BIOS al momento del encendido y anote la versión #. Vaya al sitio web del fabricante con la marca / modelo de su computadora. Vaya a la sección de soporte / descargas y vea si hay un BIOS más nuevo.

• Por último, y muy probablemente, si se trata de una máquina más antigua, el compuesto térmico que se encuentra entre los procesadores y su tubo de calor / enfriador de ventilador debe volver a aplicarse. Esto requiere algo de experiencia técnica.
