We had to "pop the hood" so to speak in a recent discussion and found software conflicts. You can tell more and read what we found at Overclocking advice.

Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
