I'm inches away from considering this a troll post...buuut...
First of all;
- You simply need to get a DVI cable, or if your monitor doesn't support it, a VGA to DVI, or a converter between them.
- Check your monitor, see if it has a similar port as the ones on your GFX card.
- If yes; Go to a local dealer and ask for a DVI cable. If they ask, it's female to female.
Yup, that's the one:

- If no; Still go to your local shop and ask for a 'VGA to DVI' converter. The converter needs to be VGA(male) to DVI(Female).
Second:
- Go to NVIDIA.com and download new drivers for your GFX card.
That's only going to work if the GFX card is recognized by the system and properly connected. Or functional at all. If downloading drivers and rebooting your pc does not work (of course AFTER connecting the right cable), I advice you to bring your PC to someone that knows what he's doing.
