windows 7 drivers for HP Pavilion 17-e055nr

Hello, 

I bought a HP Pavillion 17-e055nr and reinstalled a windows 7. Windows 7 cannot find the drivers for wireless network cards(both wireless and wired)/ blue tooth controller/ USB controller

But I could not find the drivers your website (it only has drivers for windows 8).

Could you advice where I can get it? What chipsets does it use?

thanks.
