Mesmo quando não tenho nada aberto, exceto o firefox, o computador está funcionando sem problemas. Desacelerando, ficando quente. Eu provavelmente instalei um monte de programas desnecessários enquanto tentava colocar várias coisas em funcionamento, algumas das quais poderiam estar rodando em segundo plano o tempo todo e enlouquecendo meu computador.
Eu gostaria de saber uma solução para isso, algumas coisas que eu posso desinstalar por exemplo.
Eu tenho um Dell Inspiron 1545, 4GB de memória RAM, processador dual core .. t algo .. eu esqueci. Não é a idade do computador ou qualquer coisa que é o problema, porque com uma instalação limpa funcionou lindamente.
