Which board do you have?
Changes in software-setup shouldn't affect this directly because this is all low-level, software shouldn't be able to touch this in any circumstance since this is all hardware-based.
Wiping wouldn't yield any measurable changes for you.... the problems seems to lie within your BIOS-(or more likely: UEFI-)configuration. That should be the culprit because everything happens there...
What settings did you exactly setup in your BIOS?
By the way:
I am using the Asrock 970 Extreme 4 (
http://www.asrock.com/mb/AMD/970%20Extreme4/ ) - and it all works flawless for me. My PC can be turned on via my remote, my keyboard and WOL (only thing bugging me is that sleep actually isn't working at all - when I turn to sleep-mode, my PC just goes ahead and wakes itself up again; Nothing I can do about that (yes, I tried with everything disconnected
) and hibernation is a really, really strange thing - when I turn to hibernation, I cannot turn my system back on after it went off; I can do whatever I want - pressing something on the keyboard or remote, sending WOL packages, pressing the power-button in the case: This system just stays powered off. Only solution is to switch off the power-supply and switch it back on, then the systems boot up (from hibernation, by the way); I just don't care overly much because I tend to shut my system down anyhow (SSDs are making the system so incredible fast, I don't mind booting fully))
