io non stò + a capir nulla..qui sembra perfetto,lo tengo anche acceso 5 giorni di fila e non succede nulla...ma quando facco certe operazioni...si blocca, x non parlare quando ho dovuto reinstallare winxp (hd già formattato) che si bloccava nella schermata blu dove premere "f6".....AIUTOOOoooo
grazie di cuore a tutti.. allego le informazioni prese con il software sandra:
