Hello, everyone.
I recently built a PC for the first time, and the mobo is a ASRock h170 pro4s.
It doesn't have an optical drive, so I followed the instructions to use a bootable Usb to install Windows 7 Ultimate on it.
I had some hardships, but in the end I did it.

Here comes the problem: installing any kind of driver.

I know for sure I have to install the drivers for my graphics card and for the mobo, but I still miss the most basic ones: for that reason I can't connect to internet.

When I'm in UEFI (or BIOS, I'm not sure how to call it), every USB port works, and the computer can detect keyboard, mouse and USB Stick.
When I enter Windows, though, my Pc stops detecting the Usb sticks. I can still use the mouse and keyboard, but the stick is nowhere to be found and it doesn't show up in storage or disk management.
I've tried 2 different USB drives, both of which work on every other computer in my house.

I have seen and tried to switch every possible option related to USB detection in the UEFI (And some forced me to reset everything by extracting the battery, since I had no more control of mouse and keyboard), enabled Legacy USB support in the BIOS, tried both USB 2.0 and 3.0 slots, but nothing worked.



Can someone please help me?
Keep in mind, as you might have noticed, I'm pretty ignorant with computers, so you'd do me a favor by being as clear as possible.

PS: I know this stuff only happens with WIN7 but I'd hate to change to Win 8 or 10, since I really dislike the app system and find myself at home with win7 or Xp.

Thanks in Advance.

Wait, it would connect anyway thanks to the special mode ? I will try.

Update: As I thought, it didn't work. I told you I can't connect to internet in any way, I miss the drivers; that's the point.
