I was given an old Dell 8500. formatted hard drive and installed fresh copy of xp sp3. prompted that time and date wrong during setup. cant change in bios cause "configure disabled". it says i have to enter the admin password in order to change configure from disabled to enabled.if I don't enter anything it says "invalid" and wont switch, defaults back to disabled. how can there be a password if i have not set one? very frustrating because date is set to june 2005 and time is way off. Things I have tried: Result: set time and date in control panel. Settings do not stick. Three different password reset/recover programs. Shows no passwords present.
