Hello everyone, I recently got a new GTX 660 to support my other 660, and when I go to NVidia control panel, there is only the option to disable SLI. It says to connect my GPUs with an SLI bridge, but I have already done that. Also, the sound is not working either when I put in the second one. My current specs:

i7-4770k 3.5ghz
8gb patriot ram
Z87-A motherboard (supports SLI)
1tb 7200rpm hard drive
650 watt power supply
