Product: HP Pavilion dm1-4020sa
Operating System: Microsoft Windows 10 (64-bit)
Hi,
Using a HP Pavilion dm1-4020sa Entertainment Notebook PC.
I've just done a clean install of Windows 10 (build 1511) along with all subsequent Windows Updates. I'm currently missing a driver on PCI Express Root Complex (code 28) and despite my best efforts to find the missing driver (I've tried using HP Support Assistant as well as searching the HP Website and Google), I can't find what I'm after. Please can you help?
The hardware ID information is as follows:
ACPI\VEN_HPQ&DEV_0004
ACPI\HPQ0004
*HPQ0004
Please let me know if there's any further info you require.
Many thanks,
Lee
