Nevermind,
Have you installed the chipset drivers for that model? Also, what drivers have you attempted to install from the HP website? Have you used the Windows Vista drivers in case HP has not yet released Windows 7 drivers for your current configuration?
Also, Microsoft does have an official Windows 7 Support Forum located here Link Removed . It is supported by product specialists as well as engineers and support teams. You may want to also check the threads available there for additional assistance and feedback.
