Scusa la mia ingnoranza, ma cosa vuol dire composizione? E' lento nell'aprire word, excel nuovi da utilizzare oppure file di word e excel. E' lento nel navigare in internet e., nel passare da una pagina web ad altra. Considera che uso una chiavetta per internet. Certe volte e più lento di altre volte e viene voglia di ... picchiarlo! E' grave ? Beppe

Dopo la d'orecchie, che ancora mi bruciano, ti presento la mia famiglia:
ASUS X70A - acquistato 2004 - CPU 64 M300 - HDD 320 GB - Memory 4GB - Wireles 802.11 n - ODD DVD Sup MTI (tra l'altro non riesco più ad usare il lettore DVD) - OS Win 7 Premium - 15,2 GB disponibili (80%) considerando che NON ho in memoria filmati, foto o musica.

mi sembra sia tutto, ti dò un altro consiglio prima di effettuare cose sulle quali non ti senti sicuro segui le indicazini di Kyron, posta il log in sicurezza virus lì troverai maggior assistenza, poi verifica i risultati con quello che ti ho proposto
ciao Brescianelcuore
P.S puoi sempre provare ubuntu da una live senza installare nulla oppure partizionare il tuo HDD in modo che possa contenere i due S.O

Se non ho letto male hai solo 15Gb di spazio disponibile sull'HDD troppo pochi cerca di liberarne altrettanti vedrai che il sistema ne trarrà beneficio.

Grazie per la precisazione Al.
