Hey guys im new here and was wondering if I could get some advice. Ok I have the Asrock z77 oc formula motherboard and an intel 3770k. I have been using the IGPU until recently. I just got my geforce 680 in and cannot get it to work. My monitor is not getting any signal from it. I have made sure that my power connectors are connected to the card. I also have switched to PCI Express in the BIOS. I even tried the other PCI express slots and still cant get any signal. I tried the card in another computer and it worked fine. What do you guys think is wrong?
