Two monitors, prompting connected and trying to get to work

My friend and I try to connect two monitors on his desk and we have the computer connected properly, but the screen is not any kind of signal to the computer (it won't turn on, just has a black screen or say in power saving mode). The main monitor works (of course, as l write this) it connects to the NVIDIA DVI (a video card installed) card, and the second monitor is a VGA. The second monitor we want to plug that we want to use on the OLD card came with the computer video, and we have the ports for it. However we are unable to operate, and it is quite frustrating. We have tried to update the software, but we think he may have disabled the second video card without meaning to, and we know many things at this point:
1 can I use two monitors to two different computers and use them to do different things (for example use it to surf the two different sites with two different keyboards/mouse, or play two different games (our intention is to play WoW the computer off) in this way)?
1a. If Yes, can someone please a link to a site that would be easier to read and understand? (We were already posted some, but they are confused or just say the same things and do not work)
2. how to reactivate the video card should it be disabled? Once again, the simple steps please.
3. can we use two separate video cards to run two different items on the computer, or would both forced to run out of the video one card?
3. If so, is there someone who can explain how to bind a monitor with a video card and not the other?

Hi warpedchocobo,

Windows detects and identifies each monitor and projector that you connect, and applies the video settings that are best suited to each display. When you connect an additional monitor for the first time, you can choose how you want your desktop to appear on the screen. In addition, Windows collects information about the video capabilities of the additional screen, including the size of the screen, the screen resolution and the color depth.

On Windows Vista, older XPDM drivers still work and the behavior of multi-monitor with XPDM drivers has not changed, because the operating system uses the existing graphics stack.

However, the Display Driver Model WDDM (Windows Vista) brings fundamental changes to the management of several graphics cards and external displays. This includes a new restriction, because WDDM drivers do not support multi-monitor «multicard and heterogeneous» implementations
