I have a EVGA 132-CK-NF79-B1 nForce 790i Ultra SLI Motherboard +C2D 3GHz I tried to add a zotac GeForce gtx 960 . The Pc will not boot, I get the ALX logo and then it restarts and just keeps repeating this cycle, It does not even get to the point of making the key board active. The Pc originally had 3 gforce 270 cards in it, if I stick one back in then everything is fine so I know I have a issue of some kind with new card. I have read that maybe I need to update the bios, I am not the original owner of the Pc so I have no access to my Hive. If I update the bios from EVGA website will that kill my lights and do you have any suggestions what's hanging up the pc.
