Check the PCI express (PCI SW)switches for the graphic cards. They must be Off. I have the same problem before with my rig. Page 7 of the PDF manual ( http://www.gigabyte.com/products/product-page.aspx?pid=4484#manual ).
Good luck.

Checked the PCI switches and they are all set to off. Also tried display port with dvi.

Same symptoms, I thought originally it may have been switching to a different display, hence the display port. But no, it just hangs on a black screen after listing all the drivers etc.
