I got all the issues you were having. I did not know that re installing Windows will resolved that though that idea crossed my mind but never had the chance of doing so. Then sometimes I noticed that when the computer is at sleep or hibernating it takes time to wake up for around 20-40 seconds. There are times also that my PC always fails on first boot when the PC is unplugged but works by simply resetting the unit. In rare instances, (happened thrice with in 3 months) It boots to Windows but only loads Windows defender on the system tray and never load AI suite and rest of the start up applications, It still works not until you launch any other program. It will just freeze then powering it down is just the option I only have. But the time it boots again to windows it does the same thing and I finally got it to work by multiple resets and unplugging the unit. Then one day the PC will not boot anymore to BIOS. Monitor is all black with no output, Video card, case fans and CPU fans acts normal. Q code 13, 55, 4C cycle. Found out that its the board since all my PC components are working and ended up sending it back last Nov. 1 2016 and until now it was not returned yet! Well, welcome to the Philippines :). Retailer told me to wait at least another month. Sad, But I am not troubled because I bought a temporary MoBo Asus H110M- D D3 right after I send back my Mf8 for RMA. My temporary board is working better than my Maximus Formula VIII for some reasons, Never got the same problem with Mf8. Fast boot times, Instant wake up's from hibernation and boots without flaws from cold or warm boot. The only problems I had is this annoying crackling sounds with my speaker via HDMI to TV which I got also with my MF8. External speakers is not affected connected straight to the MoBo, So I did not care then got a new GTX 1060 yesterday and the issue turned worst. It has the same issue with HDMI sound output on TV and now it affects the External speakers as well. And guess what?! From hibernation, it wakes up now for more than 1 minute? So is the GTX 1060 broken? I hope not for waiting 2 months again for RMA is not very pleasing. But I just reset the Windows 10 OS and hopefully that resolves the issue. I will check and take some test/s later and see if the crackling sounds disappear w/o any driver installed yet. Will test with generic windows drivers for sounds and video. And will never install AI suite III again since that app is very glitchy and cause underlying problems. Then install's specific drivers one at a time to figure out which driver is causing the problem. If it all works then I conclude that its AI suite III messing around. (Did uninstall this app but cracking sounds persist, Found out that other AI suite components cannot be removed. The link on the ROG site to clean AI suite fragments are broken so I ended up resetting the PC 🙂
