This isn't as simple as we were thinking, actually it's easier for us to assume or to give you the specific solution and link if askers mention the Operating System installed on their system. Since you didn't mention, I have to assume myself, I can't give you the direct link, but I will only give you the link where you can download the drivers with instructions on how to do.

More than that, there are three Compaq Presario v2000 Pc notebook models, well from the links below, select what is best for your system.

1. Compaq Presario V2000 Cto Notebook Drivers.

2. Compaq Presario V2000 T Cto Notebook Drivers

3. Compaq Presario V2000 Z Cto Notebook Drivers

Open the link, select the operating system installed on the system and click "Driver-Audio" to download Sound Drivers and "Driver-Graphics" to download Video Drivers.

If you have problem, let me know.

Good luck.

Thanks for using FixYa.
