I have a Intel 945 S-Series MotherBoard. I recently purchased GEForce 9500 GT graphics card. I have PCIE slot on the MB. when I fixed the card in the slot and tried to boot the system, it doesnt show any display however system is booting. BIOS doesnt show PCIE slot but it shows PCI1 & PCI2 slots. How to make the BIOS detect the slot?
