Hi:

What is the full model number or product number of your dv9000 notebook?

The product number can be found on the same sticker as the serial number.

You need to manually install the Vista nVidia chipset driver from your notebook's support page, but there are at least two different versions based on the exact model.

OK...

Download and run this driver.  It most likely won't automatically install the device.

This package provides the driver for the NVIDIA nForce AR Chipset in the supported notebook models and operating systems.

If the driver didn't install...

Go to the device manager and click on the coprocessor device needing the driver.

Click on the driver tab.  Click on Update Driver.

Select the Browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp37730.

Make sure the Include Subfolders box is checked, and the driver should install.

Then restart the PC.

Thank you for the fast replies, I would've got it done sooner if I didnt have to go to work. The problem is fixed and everything's working just fine.
