Hello,

I have 2 months old PC:

MB: ASUS ROG Strix z370 g gaming (microATX)
CPU: I5 8400
RAM: 1X DDR4 16GB PC 2400 CL17 Crucial Ballistix Sport retail
GPU: Gigabyte gtx 1060 3GB
OS: Windows 10 x64
PSU: be quiet! Pure Power 10 600W

The last 2 months the PC work perfect. Last week I let the PC on overnight and the PC went into sleep mode. After that the USB 3.0 and USB 2.0 Ports on MB not working, just the 3.1 USB ports are working. The problem is not only in the USB ports, but also the fans are spinning after shutdown the PC.

I've tried already:

- reinstall Win10 and update
- try Ubuntu live from usb (usb 3.1 port)
- update bios to version 0612
- reset CMOS
- try to reconnect all cables
- reinstall usb driver (in Device Managar )
- bios config. , fast startup off, and so on ...
...
but nothing is working!

What can I do? I need my PC every day for recording and that's way i need all usb 3.0 ports. I was searching for an answer on google and I found that ASUS MB have a lot of problems in the past with usb ports and shutdown ... I'm afraid to send the MB back to them (warranty), because if I get a new on it is possible that the problems come back after 2 months ...
Have everyone experience with that? What should i do?
