so i bought a gt 610 and installed it. my computer didn't detect it because it didnt come up on the drivers. i tried everything and so i thought it might be faulty so i returned it and got a gt 630 but now the same thing is happening the fan works but its just that when i plug my monitor in theres no display and when i put the cd in it says install vga driver. please help. it might be because of the stupid integrated graphics card.
