I'm going to guess it's a laptop and since you have not listed a model number I can't point you to it directly.
Go to the manufacturers website they will have all the drivers you need. You will need to know the model of your laptop. There may be other drivers you need as well such as USB drivers. Get eveything they have listed for your device.
You can download the drivers to a thumb drive or even burn them to a CD or DVD if you need a way to get them on your computer without internet access.
