Hi everyone,
I have problems with my computer and can not solve them in any way. when i do a fresh installation of windows everything is ok, but when i install the drivers, problems start. If I browse the Internet on the primary screen and watch the video on secondary screen, video will lagging. Even in games i can see that something is wrong with the computer, because the games don't work smoothly either. And why PC need 20 or 30sec to turn of? I would be very grateful if anyone could help me solve these problems!

Mobo: ASUS MAXIMUS XI HERO
CPU: i7 9700K
GPU: RTX 2070 SUPER
RAM: Corsair 16GB 3000MHz
