Since upgrading to Windows 10 Pro, almost every shut down is reported in the Windows 10 Reliability Monitor as the computer was not shut down properly. This happens on both shut downs and restarts using the Start - Power options.

I first saw this after an upgrade over Windows 7 Pro. I then installed clean using a USB ISO and I ended up with the same thing. I then installed from a Microsoft original DVD and again, ended up with the same thing.

This happens before I install any software at all, including antivirus. The system appears to run fine and there is no error message on the next boot to say that the system was not shut down properly. It is only apparent when checking the Reliability Monitor.

I ran sfc /scannow and there are no problems. My Device Manager shows no problems. Msconfig shows the system is set to Normal Boot.

I did not use the Mother board CD to install drivers as many of them are outdated and probably incompatible with Windows 10 anyway. I installed the most current drivers on the Asus website.

I am thinking that this is a hardware issue related to a driver for the motherboard. It can't be a fault with Windows after three install's. It can't be a fault with any software on my system as it happens on a brand new install of Windows.

Anyone have any ideas on where I can look to find the source of this irritating issue? What motherboard driver might I have missed?
