Mouse and keyboard not working, what should I do?

Question

Keyboard

I assembled a gaming computer with such a filling.
Intel i7 8700 BOX, Nvidia GTX 1070 Ti founders edition, ASRock z370 PRO 4, 16 GB RAM Kingston HyperX Fury Black (4x4gb), PSU Corsair CX 650W, HDD Seagate 2 tb, ssd intel s575 256 GB.
What is the actual problem.
The problem is that I want to reinstall Windows, I can’t do this, because the mouse and keyboard do not work when the installation starts. (The backlight is on, but the cursor does not move, and the keys on the keyboard do not work, I can not even press the "next" button).
What to do?
I did not find a clear answer on the Internet.
Please help, I would not like to realize that 100k was thrown to the wind.
I decided to reinstall because I ran Windows from the previous disk, threw out the death screen with the error "STOP: 0000007B" (and many other characters
