Por que meu Ubuntu 16.10 congela tantas vezes repentinamente depois de alguns meses?
Eu tenho que pressionar o botão iniciar / reiniciar na minha máquina para reiniciar o sistema.
Então funciona, mas depois de alguns minutos fazendo coisas, por exemplo. navegando na internet, trabalhando em um software, etc ele congela novamente - tudo, chaves e mouse e tudo, pára de funcionar!
Alguma idéia do que pode estar causando isso?
Como posso verificar o que está acontecendo no meu terminal?
Estou sendo hackeado por vírus?
Estou usando o Skull Canyon e é exclusivamente no Ubuntu 16.10 - Kubuntu Plasma 5.8.
EDITAR:
Uma captura de tela quando ela congela - como você pode ver, a maioria das CPUs está chegando a 100%!
Por quê? Isso nunca aconteceu antes!

Capturei a captura de tela quando ela congela com top no meu terminal. Eu não vejo nada está causando o congelamento.
