So after building a computer for the first time ever today, i have run into a problem why am i only getting 4 bit colours. Here is the situation after i install xp SP1, my colours are fine. But once i install my nivida video drivers my colours go to 4bit. when i upgrade to xp sp2, my colours go back to normal, again i install my video drivers and back to 4 bit it goes. How do i fix this? Thanks
