You will have to provide more information.

What kind of machine is it? Homebuilt, pre-made? Please provide make and model.
Did it come with an installed OS? With a CD that contains drivers? Can you use those for now?
Why do you think you need drivers? Did you install a new OS, or did something stop working?

Usually you go to the manufacturer's site and download the drivers for your model, for the particular OS that you have installed. We would all be happy to help in more detail, but we need more information to give you a specific response.

---------------------

Please satisfy my curiosity. How did you find Tom's, and why did you specify that you wanted the drivers "for free?" Nothing at all against you, but there are an awful lot of such queries on the forum and, since almost no-one charges for drivers, I'm wondering if there's some piece of information out there suggesting to people that they ask us where to find free drivers.
