Graphics problem with Abit NF7-S

[3xistenc3]

The AGP slot on the board (8x/4x) will not display anything on the monitor from the cards I put in. I tested with 2 cards, and both work fine on other systems. Did I install some cords wrong? Anyone have any ideas?

hmmm.... Sounds like a duff board to me.....

Yep, I think I'm convinced.
Any other ideas before I send it back?

Do you have any bios beeps when you power the pc up?
