  1. Sounds like a BIOS problem. Check your BIOS settings for adjusting the lanes for the PCI-E bus.
  2. Is the card seated correcly?

    On another note I've seen people turn a 16x slot into an 8x or 4x slot scotch taping the pins on the card itself. I know of course this isn't what's happening to you, but i figure if there is something in the slot itself obstructing the connection, might be the case. Just a thought.
