Ciao,
il log é pulito,dovresti solo aggiornare il sistema e installare il ServicePack2...
http://update.microsoft.com/windowsupdate/v6/thanks.aspx?ln=it&&thankspage=5

Di niente figurati....
Per quanto riguarda il SP2,appena uscito c'erano stati dei problemi,ma adesso non dovrebbe dartene se lo installi,comunque era solo un consiglio,poi vedi tu...
