Hey I just bought a new XFX 6570 graphics card along with an Antec 430w Earthwatts. I disabled my integrated graphics card on my narra5 motherboard. Also I switched my BIOS' primary video output to ''PCI-ex16'' since I am going to use that slot for the card. When I attached the card, I made sure to firmly press down on it and secure it. But when I turn on my computer there is no display on the monitor. I am using a vga connector on my monitor and graphics card. I don't know what's wrong. Is my PCI-ex16 slot on my motherboard broken or did I miss any steps in installation?
