It helps to uninstall the older drivers first........then under device
manager uninstall the old video card.
Shut system down and remove old card...........install new card and reboot.
Install the new drivers

It really does not matter which DVI plug you use the card will sense the
connection and no you will not lose 1/2 the picture...........
The 2 DVI connections are designed to be able to use 2 monitors

Hi...
Sorry if this is a vid card newbie question...
I am in the process of upgrading my graphics card to a 7800GS AGP. Do I
have to remove the old video card drivers first... or just overwrite with
the new drivers?

Also my monitor is an older 17" Ilarma CRT with a 15 pin 'D' plug, I
notice that these new vid cards don't have a 15 pin 'D' socket... but two
square(ish) looking jobbies that I think are called DVI...? I have a
single adaptor from DVI to 15 pin... but which of the two DVI sockets do I
use? Will I loose half the graphics output by only using the one DVI
socket? Again, apologies if I am being blonde here... but I have not
messed with these newer cards before.

Dave
