I have an older CRT that goes white when the VGA CABLE is unplugged.
Time to check your setup. Find both ends of that VGA cable.
Dell Inspiron 1200, 6years old, XP, sp3. When I start my computer I immediately get a white screen. F8 does nothing, blank screen stays. So now I cannot do a safe mode start or last known good config. Anyone have any ideas?????
