If you are able to swap its slot then this is not an AGP board which means its a PC or ISA card which means it is old, as for swapping drivers all you have to do is before you deinstall the board set your
video driver to the default windows driver...it really isn't as hard as you might think...but it is way easier if you can watch someone else do this stuff before you have to do it yourself...sorry you had such a hard time for somtheing that should have been simple.
