I know that many times I must install the chipset package first but I leave that to you.
Did you try the laptop drivers from NVIDIA.COM? Links to show how I find it:

It's about the third link or:
My VGA card got lost after formatting my laptop computer from a windows Vista home premium to a Windows 7. The Windows Vista was actually posing serious problems, always coming up with this blue screen after every 1 hour 30 minutes.
Give me links other than Support/hp, where I can get this driver to download and install
