(I suck with computers and know nothing about them but here goes nothing) I have tried all day to do this and need some major help. I have an Nvidia video card built in to my computer. i just bought a radeon 9600se.(it is AGP). To install it says i must first install an agp driver from the the motherboards chipset or whatever i dunno neways it has a list of site but not for for nvidia..... so i went to the nvidia main site but they do not offer an agp download. I skiped this section thinking sense i cant find one then mabe it will work neways so i unistalled old graphic card software. And then installed the radeon card but i keep getting a black screen(with both video cards). SO i took it out and the old card worked again so now im stuck what can i possibly do to get the new card to work please help!!!!!!!!!!!!!
