Hello, I am trying to get 3 monitors working with my system. Two of them are 23 inches and each have inputs for VGA, DVI, and HDMI. I have a second, older monitor that only accepts VGA. I am running the two 23 inchers right now off of a Radeon HD 7950. One is being fed from the HDMI port. The other is being fed from a mini displayport to HDMI adapter. I also have a Radeon HD 6670 in there. I want to run the third VGA monitor with a VGA cable to a VGA-DVI adapter. I thought I could just plug it in, but it seems that that isn't the case. What are the steps I need to take to get three separate monitors running? Thanks in advance!

Should be fine then. You may have to reinstall the AMD Catalyst drivers to ensure that the necessary drivers are installed for the different cards.

Also try installing AMD Hydravision, it's their multi-display management tool

I found a configuration that works, but it is not what I want:

secondary 23 incher in mini displayport to HDMI adapter on 7950. Main 23 incher in HDMI of 6670. Old VGA monitor in DVI to VGA adapter on 7950. For some reason, the DVI port on the 6670 doesn't want to work.

Try it in the primary slot on its own and see if it works, try with a different cable as well. If the DVI doesn't work whatsoever then it's faulty.
