Need Video Card to Dual Monitors for One PC

I need a video card to set up dual monitors for One PC.

My PC:

Dell Vostro 200
Intel Core 2 Duo CPU
EA500 @ 2.20 GHz
2.19 GHz 1.99 GB of RAM

Adapter Informtion:
Adapter Type: Intel G33/G31 Express Chipset Family
Chip Type: Intel GMA 3100
DAC Type: Internal
Memory Size: 128 MB
Adapter String: Intel G33/G31 Express Chipset Family
Bios Information: Intel Video BIOS

Monitor: Dell 20" Widescreen Monitor (E207WFPC)

I have several other VGA Monitors that I might use or may buy a new one.

I am not sure if my PC with the current configurations is capable of using Dual Monitors. I bought a Y cable and followed several instructions on how to make it work. I have done it before on another PC and it was a simple process, so I'm guessing my video card does not support it.

My first question is with the specs I have, does it support it? If so, can someone give me instructions of how to make it work?

If it does not support dual monitors what type of video card or other hardware/software if necessary do I need? And if you have a suggestion can you also supply install instructions.

Thanks for your help!
