Since this is my first thread, I first want to say hello to the Asus ROG community.
I want to reset my Maximus Hero VIII mobo to the factory settings via the Clear CMOS button. But I am not totally sure how to do that. In another thread, I saw that Nate152 said, that you have to power down your pc and then press the button for 3 secs. What does "power down" in this context mean ? Do I just have to shut down the pc, still connected to the electrical outlet with switched on psu, or do I have to disconnect the pc from every power source (as if I would do, when I install new hardware) ?
