Meu sistema funciona bem e então congela aleatoriamente.
Na maioria das vezes eu apenas espero por alguns segundos e o sistema é bom.
Ocasionalmente tive que reiniciar, mas isso aconteceu apenas uma ou duas vezes.
Você pode analisar e dar sugestões sobre o que devo fazer para que seja mais suave?
Instalei o sistema operacional Ubuntu do DVD para a unidade USB sem modificações na instalação. Eu removi temporariamente o disco rígido para forçar a instalação na unidade USB.
