After using Ghost 9.0 there is no display

I tried using ghost version 9.0 to build an image on a Dell Optiplex GX780 that has dual video card built in. After rebooting the computer MS Windows XP SP3 splash screen comes up but when the blue screen before the login windows shows up I lose the display. The display goes black and I get an amber light on the monitor. The keyboard numlock and caps lock still work but no display. I can see the login screen in SafeMode but can't login because the password has changed to something else. I tried using ERD to unlock the account but it doesn't work. The computer worked just fine before I ghosted it to an external USB drive. I tried putting the image back on the system and I get the same thing.
