  Hello

  Using a HP Pavilion dm1-4020sa Entertainment Notebook PC.

  I just did a clean install of Windows 10 (build 1511) as well as all Windows updates. Currently I'm missing a driver on PCI Express Root Complex (code 28) and despite all my efforts to find the missing driver (I tried to use HP Support Assistant as well as the HP Web and Google site search), I can't find what I'm after. Please can you help me?

  The identification of material information is as follows:

  ACPI\VEN_HPQ & DEV_0004

  ACPI\HPQ0004

  * HPQ0004

  Please let me know if there is any more information you need.
