PCI%5CVEN_8086%26DEV_31A8%26SUBSYS_84D4103C%26REV_03

Please, help me. Thanks.

Hi:
Unfortunately, no one can help you because Intel did not develop any W7 USB drivers for the USB 3.1 ports your notebook has.
Nor are there any graphics or wifi drivers for W7.
I suggest you reinstall W10 x64, because that is the only Windows OS where everything is going to work.
