So my friend wants to play a pc game (World of Warcraft) that does not support the S3 Prosavage graphics card series so he ordered a new card: Chaintech VGA Geforce 7600 AGP 4x/8x from Nvidia. He says his motherboard only supports 4x which is why he bought this card which claims to be "4x/8x". However, after he installed the new card (without disabling his onboard Prosavage graphics chip)and restarted the comp, his monitor doesn't come on. What's the problem here? Supposedly, Chaintech VGA 7600 AGP 4x/8x from Nvidia is compatible with computers that have onboard graphics chip. The instructions say to just install it and it should work. Has anyone had this problem?
