PC VGA TV Cable problem

[tinteena]

I'm setting up a second monitor on my work pc. How do I install a video card without disabling the vga port? I have a new Dell Vostro running Windows 7. When I connect the ATI video card into the PCI slot, only the monitor connected to the new video card works, the main VGA port is disabled. How can I enable the existing vga port to allow for dual monitors? I had it working on my last pc and now it is not.

In this case, the best option would be to get a video splitter cable that would allow for dual monitors.
