Ugh. St1ckM4n is thinking along the correct lines...
I'm going to be a bit more patient though. Your question doesn't include very much information, and on the face of it, Sticky is right, the answer is No.
However, I suspect you just aren't using the right terms. What hardware is in your computer? If it really is "PCI and VGA" then yep, you are hosed, that is stuff from 15-18 years ago. However if you mean PCIe and are just confused about monitors, that is an entirely different thing.
