I recently bought a second EVGA GTX 760 sc acx to add to my pc. My motherboard is an MSI Z97 gaming 5 motherboard. I have an i7 4790k cpu. For reason, my computer won't detect the second graphics card. I have an 850watt PSU from seasonic so that is not the problem. Could someone help? It is not detected in windows, or gpu-z. Is there a setting in my BIOS that disables the other slots? If so could someone tell me where it is? Thanks!
