LOCKED OUT no vista or xp

i have tried vista twice before and when it restarts and sys finalising
installation, the screen goes on standby but the computer is still on so i
have to restart and it says the installation was unsuccessful. this time it
restarted and asks me whether to run vista or xp. So i clcik vista and the
bar loads then the monitor turns off again and the computer is still running
and if i try to access my old xp it asks for an administartor password and i
have set NO passwords to get onto my computer. PLEASE HELP

Leave the Password field blank and it should work

Your not, by chance, using an ATI RADEON 9xxx card are you? I am not sure if
it extends to other video cards (manufacturers or types), but in my testing I
have confirmed that the Microsoft provided driver for my R9800pro is
definately broken. Every time you receive a UAC prompt, or logon screen, it
appears completely black (monitor in standby). I found by blindly hitting
"enter" or entering a password and pressing "enter" will get you past this.

After getting the interface to display I immediately went to Windows Update
and found a new driver. After installing this, the problem went away.
