Always a good idea to include your troubleshooting steps in your first post.
That way it saves both your time & ours!

I know you said you tried with one card only already but just want to ask if you have tested each sepreatly and if yes i would try uninstalling then reinstalling the video drivers. Anyways reseaon i mention if you tested each card seprate is because one card could be bad and about the drivers because you might not have the apporioate drivers needed for sli. Just a suggestion. So try card number one by its self and if it runs fine then its good then take that one out then try the other card and it runs fine then its good also but if it doesnt run good then theres something faulty with that card. Could be also that your power supply is not supplying sufficient enough power to both cards so it could possibly be the cause of the black screen. would be good to know what kind of psu your using also to know whether it's up to the job of running two cards.
