Where can I find the driver for the co-processing in a studio XPS 1340 with Windows 7?

I recently bought a dell xps studio 1340. It is a great computer, but Vista is not my favorite so I put Windows 7 RC on it. Every driver is working correctly, except a device called "co-processor. I do not have to find this driver. please help me.

It would help to know what exactly located in the Control Panel -> Device Manager says that is not working properly. There is a thread XPS 1340 Owner's here you can ask at: http://forum.notebookreview.com/showthread.php?p = 5209097 The looks like it's probably an NVidia NForce driver you need.
