XFX Radeon 7870

I have a XFX 7870 Double D card with dual dvi dual display ports and hdmi port. I have 2 dvi monitors however for some reason only the top dvi port works. I confirmed this by plugging in both monitors and only 1 turning on. and plugging in 1 monitor by switching the slots. Meaning only the top dvi one is working. faulty card or anybody else have any ideas?
