Note congelando e só volta quando desligo direto no botão

[victorbaeta]

Olá, pessoal.
Estou com o seguinte problema: comprei um note não faz nem dois meses e troquei o sistema para ubuntu logo após e algum tempo o note vem apresentando congelamentos (congela tudo, não move nada, não funciona nada, nem crtl+alt+f2).
Alguém poderia me ajudar a descobrir o que pode está acontecendo pois está me atrapalhando quando estou fazendo trabalhos da faculdade e ele congela e tenho que desligar, perdendo todo o trabalho.
Obrigado.

olá,

em primeiro lugar, você deve passar um memtest completo ( leva uma noite inteira).

Entre nas opções avançadas do GRUB e escolha memtest.

Feito isto e descartados problemas de erros em pentes de memória, siga este roteiro:

a) use a maquina até travar. Reinicie e examine o log do sistema para ver o que travou e em que momento.

b) entre em terminal e invoque o comando top ( digite top na linha de comandos). Deixe o top aberto num canto da tela para ver o comportamento dos aplicativos e memoria até obter o travamento. Examine o top.

c) Crie um novo usuario. Utilize a maquina neste novo usuario para verificar se o erro se repete. ( algum pacote mal comportado instalado no seu usuario e não instalado no novo perfil podem esclarecer o travamento.

d) abra o GRUB e entre em modo seguro para ver se trava.

Para corrigir este sintoma, é complexo, pois vários fatores podem contribuir para isto. Memorias com problemas, hd com problemas, programas com problemas, interface grafica com problemas.

É o caso de se isolar um a um os possiveis causadores e tentar isolar o responsável para depois se tentar corrigir.

Ok. Vou fazer tudo isso e respondo aqui logo mais. Só não sei o momento certo em que vou responder porque os congelamentos as vezes demoram  a acontecer. Obrigado mais uma vez, Tota.

Voltando aqui com a verificação do log após travamento. Segue a cópia do momento após reiniciar o note:
