I have a hp pavilion g6 2270dx that was running windows 8. I reformatted and installed Windows 7 Pro. The installation worked but I have no drivers for the Ethernet controller, network controller, PCI device, SM bus controller, 2 USB controllers and an unknown. I have tried to download the drivers on another machine and transfer via USB but nothing is working. Any help on what drivers I need or if I'm missing something would be appreciated.
