Il computer era già da qualche giorno che aveva una connessione limitata o assente, premetto che ho un router wireless, ma andando ad inserire un IP predefinito la connessione funzionava, poi mi è venuta la brillante idea di utilizzare Cleanup and Repair e da quel momento la connessione non è stata più possibile, così ho disintallato il router e la wireless lan usb; ora il computer non accetta più nessun componente hardware e facendo delle verifiche in dos ho notato che non viene più indicato l'indirizzo IP... ho paura di aver cancellato qualche componente di windows. AIUTO!
