Meu computador doméstico está executando o Ubuntu 18.04. Eu tenho um computador de trabalho configurado de forma semelhante que está executando o Windows 10. Ambos os computadores são computadores Dell com cerca de 4 anos. No meu computador Ubuntu - quando visito alguns sites, percorro o Google Earth, processo dados - o disco rígido começa a girar descontroladamente e o ventilador liga como se o computador estivesse lutando. Percebi que meu computador Windows não tem os mesmos problemas ao fazer as mesmas tarefas. O ventilador nunca liga ao visitar sites, apenas quando estou processando muitos arquivos de imagem.
Assegurei que os componentes do meu computador Ubuntu estejam livres de poeira e que as aberturas estejam desbloqueadas.
Por que meu computador Ubuntu parece ter tanta dificuldade em tarefas simples?
Aqui estão as estatísticas para o computador com Windows 10.
E aqui está o computador Ubuntu ...

Erros AER
Seus erros AER (Advanced Error Reporting) estão no dispositivo 1c.2, e eu estava certo, essa é sua placa wireless Intel 3165.
