Bad virus, infected system, decided to do clean install, yada yada. Lost my installation CDs and everything, called Dell and had them replaced and keyed to my copy of windows. Just did a reinstall, and it's asking for a username and password to boot up - which i def don't have. No usual defaults are working, neither are passwords from previous install (Note I only ever used an admin password, no user accounts.) Tried going into setup from POST and removing all passwords, but that did nothing. Clean windows installed, almost ready to go...can't log on. Frustrating!
