AMD/NVIDIA DRIVER installed!

Originally my PC that is listed in my system specs came pre-installed with win7 on it and i backed up the driver's on a DVD, now i just browsed through just checking stuff and noticed that there is a;

AMD VGA generic driver
&
nVidia VGA generic driver

so i checked through my system and noticed that both these drivers are installed. this machine has an intergrated nvidia 9200 card.and i have AMD processors.

so should the AMD 'ati' driver be installed too?

maybe a daft question but i thought these to would conflict.

Only if you have an ATI graphics card.

Well then i think that will be a no then, i found it strange how it was allready installed on the system, just as well i checked.

thanks clifford!
