Weirdly, I can't use a software command from within Windows 10 to restart my Z170 Pro Gaming, it does the turn off part, but steadfastly refuses to do the restart bit. The light on the front of the case stays on, as does the CPU cooler, but for some reason it doesn't complete the turning off process. If you hold the power button down for around 5 secs then it stops, and can then be restarted. It will come on OK if you press the start button on the case. If you choose shutdown from within Windows it works perfectly. Everything else appears normal. Chip is 6700k with Corsair H80i GT cooler.
