Well all the drivers for your computer should be available on it's manufacturer's webpage. If you give me the brand name and model and operating system I could probably find it for you.

Well, there are several C700 models, assuming that you have a Compaq Presario C700, you can download the drivers from following link: Compaq Presario C700 Notebook PC series - Download drivers and ...You will need to chose C700 model, OS version (Windows version), then proceed to driver download page.

need more information on your hardware. What type of motherboard do you have, is the sound and video integrated, and if not, what is the make and model of your sound and video cards?

plz visit the manufacture website there you will get free download
