i have a dell 2400 using a viewsonic vg500b....i rebooted the whole system and reinstalled windows xp everything was working except i didnt have the driver for the monitor so the resolution was bad i think like 640x480 or something but i could still use everything...when i shut down the system and turned it back on the screen went black after the windows loading screen. I can hear the welcome music but nothing appears. I also tried starting in safe mode and still nothing?? Any suggestions???
