dopo aver fatto una serie di operazioni, tra le quali una partizione nuova ricavata dal disco c, e dopo varie pulizie suggerite nel post di VISTA.

Ciao black, niente di pericoloso ma è meglio fixare ed eliminare le seguenti voci:

O3 - Toolbar: (no name) - {BDAD1DAD-C946-4A17-ADC1-64B5B4FF55D0} - (no file)
O4 - HKLM\..\Run: [IgfxTray] C:\Windows\system32\igfxtray.exe
O9 - Extra button: Inserisci blog - {219C3416-8CB2-491a-A3C7-D9FCDDC9D600} - (no file)

O20 - Winlogon Notify: DeviceNP - DeviceNP.dll (file missing)

Poi una pulizia con Ccleaner compreso il Registro e sei a posto.
