I work in a hospital/university's pathology department and was recently tasked with setting up dual extended monitors. However, the machine I am working with is an Emachine EL1352-51 and only has 1 VGA port and a bunch of USB ports.
I bought a low profile graphics card from a computer part recycling store (that has 1 VGA slot, 1 HDMI slot, and 1 DVI slot) and physically installed it (as in did not install any driver software as none came with it, just the actual piece).
When I first attempted to boot the computer up, I didn't try plugging anything into the new card, opting to just see if it would boot like normal with the 1 monitor plugged into the original VGA. The computer booted successfully (with beep), and the fan on the new graphics card also booted up. However, the monitor was completely black and kept trying to go into sleep mode. I tried plugging into the new VGA port, but that didn't work either.
I completely removed the additional graphic card and rebooted and it all worked like normal with active monitor.
Oh! And of course, the computer does not have internet access and I don't think that I can change that.

Specs: (i'm not very tech savvy, so i'll just include all info i could find)

In all likelihood, when a graphics card is installed, it automatically disables the on-board graphics. There may be an option in BIOS to re-enable the integrated graphics even if a discrete graphics card is installed.

Shut down your computer.
Reinstall the graphics card.
Connect your display to the graphics card VGA output.
Power up your computer.

At this point, you should see a display.

If you do see your display at this time, once Windows completes it's boot up download and install drivers for your card/OS from NVidia.com.

I would have thought you'd have your own IT department considering where you work...

It's possible the BIOS needs to be manually set to prioritise the graphics card over the onboard graphics, or at least adjust the graphics settings in BIOS. Given the hardware it sounds like you'd need both to work together to get a dual display.

It's also possible the graphics card doesn't work. If BIOS graphics output can be chosen to prioritise the graphics card, then the PC should boot with it installed and the display cable connected to the card.
