Hi there, So I have spent a small fortune and plenty of hours planning and building my new PC. It's great!! I'm very happy with it! It has a new skylake i5 6600k installed, 16 GB of DDDR4 corsair Ram, a motherboard packed with great features (and pretty lights). The only thing about it that I don't like? Well............it won't turn off / shut down properly....Well at least I think it is not? Please help me as I am on the brink of a nervous breakdown here!!!

System spec-

Asus Z170 gaming pro Mobo,
i5-6600k CPU
16Gb Corsair DDR4 @2133Mhz,
Seasonic 850w Bronze PSU,
H80i AIO cooler,
SM951 256 GB M.2 drive (AHCI one),
NZXT sentry 3 Fan controller,
MSI GTX 970 Gaming,
All housed in a Corsair Air 540 case.

Further description of problem.......
I shut down as normal from the start menu. After the usual windows "shutting down" message appears then the signal to the monitor ( connected via HDMI) goes after about 4-5 seconds. I then wait for the fans, fan controller, and CPU fan to stop spinning BUT they don't! They just keep going as normal! The power light is still lit on the front panel!!

Now here's the odd thing, after holding the power button in for 5 seconds and killing the power manually ( which is what I have to do) and rebooting I do NOT get any messages telling me that windows did not shut down normally etc, it just boots up as normal!

I installed originally windows 10 pro 64bit and when I realised that this fault was happening, I reinstalled Win 7 pro 64 bit to hopefully get rid of the problem.....but to no avail......

Something even stranger.....Sometimes it shuts down fine and sometimes it doesn't!!

My worst fear here is that this is a hardware fault :-( . I would rather it be a software issue/ driver issue and be fixable from the comfort of my own bedroom. !!

Please Please Please help folks!!
 
Solution
For ANYONE else out there with a similar problem. Before you start applying registry changes, mucking around with power settings/ power plans/ rolling back drivers, questioning every piece of hardware etc etc....just update the BIOS.....this fixed the issue. Which is strange really because the BIOS the board came with was only about 6 weeks old! Just grateful the problem is fixed!

Hi, I have the same issue as you, and using the same Mobo, I have already updated my BIOS, search for this problem and did everything (except new install of Windows 10) but no way to resolve it,
this problem occur after several hours of usage, 6h or more with heavy usage like gaming, if I use it for 1 to 3 hours light usage, it shutdown properly, else the system apparently will shutdown software side, the screen turn off, but the case fans, cpu cooler and the case still working ! if I push power button for 5 seconds, and start it again, nothing bad happen, everything works perfectly, so the problem is when I shutdown or restart,

my Sys Specs :

Asus Z170 Pro Gaming
i7 6700K
8Gb HyperX Fury DDR4 2666Mhz
EVGA Supernova 750 G2 Gold PSU
Enermax Liqmax II 120S
Seagate Baracuda 1Tb
Sapphire Nitro R9 390 TRI-X Backplated
Fractal Design Define R5 Blackout Windowed

I'm using Windows 10 64Bit

Wow, this is the first time I ever had a computer problem, googled for it, and found a plausible solution in the very first link. Can't wait to get home to update the BIOS. My new ASUS Z170 Deluxe 6700K build yesterday did not start well. A little different from other replies I see here saying the BIOS fix did not work for them. I my case, it does a complete power off then auto restart about 5 seconds after shutdown. Very similar to the normal behavior when certain BIOS entries are updated, the PC must complete power down reboot.

BTW, I have a other problem, hopefully related. After installing Win10, there is no options related to sleep modes. The power configurations (basic, advanced, etc.) only have an option for screen disable and non for time until sleep mode. Not a big deal as I usually turn off sleep, but just want to check if you saw the same thing and if possibly related, or something I did wrong that I need to reinstall before too much time is invested.

Yup try the BIOS update. I stuck with windows 10 for all of 1 day before rolling back to W7 haha. I would say the sleep mode thing is more likely to be an OS issue rather than anything related to BIOS. Windows 10 was a little too different for me :) Post back if the BIOS update fixes your issue though!

Alas, @monkey4sale, the BIOS update (to latest 1602) did not solve my problem. After redoing all the BIOS settings (the update cleared the CMOS), no differences I can see. Still auto-restart a few seconds after full shutdown. Actually that's not entirely true. I also could not get the Ethernet ports to work right before the update (always reported as connected but OS gave unidentified network and it would reach out to the internet). The ports worked just fine after BIOS, even though the release notes said nothing about Ethernet ports.

I had already installed Win 10 (from bare metal, not MS forced updates) on all my old builds and passed them down to Wife/Son to replace their ancient systems. Yeah, quite different from Win 7, but definite step above Win 8.1, and good enough that I finally accepted MicroSoft's AdWare/Malware like OS being forced on us all and eliminated all Win 7. BTW, get Classic Shell. Makes Win 10 feel a lot more Win 7 like where it really matters, the desktop UI.

Never ran into any Win 10 setup problems until finally getting around to my new ASUS Z170 i7-6700K build. The missing power configuration sleep settings is weird but I can't help feel it is related to the auto-restart. Like some signal is broken on the MB making MS think feature does not exist and MB crash on shutdown.

With all the hype on Z170 and Skylake and ASUS, I am unhappy the build is not going easier than it has.

Sorry to hear about your troubles brother. I would in all honesty consider contacting Asus as I am sure this is a motherboard issue that I and you and others are experiencing. I may consider trying a different board. At least a BIOS update fixed my issue( in my opinion a ridiculous issue) but in your case it has not!

For the sake of closure, for anyone else seeing this. I found my problem. Actually someone else here on Tom's Hardware Forum was experiencing the same problem he traced down to the USB3 card in his system. On another forum site I found someone else who also traced the same auto-restart to his USB3 card.

While the ASUS Z170 is not shy of USB3 ports, I had a card left over from a prior build that was downgraded to another purpose and stuck it in the new build. While the other guy's USB3 was different vendor (Anker, IIRC) than mine (UtechSmart), I am pretty sure both vendors were VIA chipset based.

Removing the card solved the problem. In fact both problems. Windows 10 now presenting sleep options in the power config. I happened to have yet another USB3 from Anateck. It worked perfectly with no auto-restart or sleep setup issues.

So as a final word of warning to others: If you plan to add more USB3 to a ASUS Z170, then DO NOT buy a VIA based chipset card. Also Anateck is Amazon best selling USB3, so an easy choice. I am going to file a bug report with VIA.

For those still facing this problem, I solved it by uninstalling ASUS' Ai Suite 3 and disabling fast startup in Windows 10.

You need to check Windows Event Viewer to see what errors/warnings it's outputting during shutdown - this enabled me to figure out what was happening.

I'm running:
-ASUS z170-a
-Intel i5-6600k
-EVGA GTX 980Ti
-32GB Crucial Ballistix Sport
-Windows 10 64bit

My system would not shut down all of the sudden, display would turn off but CPU & fans would keep running. I checked Event Viewer and saw there was an error in there telling me there was an issue with the drivers for something on the ASUS motherboard, I believe it was something to do with the ASUS Ai Charger+ not functioning properly.

I also saw errors in there about Windows not shutting down properly.

I uninstalled ASUS Ai Suite 3 and the ASUS Ai Charger+ errors went away.

I then disabled fast startup (Power Options->Choose what the power buttons do->Change settings that are currently unavailable->Shutdown settings).

This solved my problem; no more errors in Event Viewer and now Windows 10 shuts down properly.

ASUS support was non-existent so hopefully this helps someone.

I've been trying to sort this out for AGES now. Brand new build PC and wouldn't shut down. Turns out my mobo comes with Killer Network Manager and the version is comes with just happens to have a massive memory leak issue which causes windows to chew all its ram AND whilst updating Killer Suite to fix that problem, it also started shutting down properly. Not sure if this was the answer but just putting 2 and 2 together lol

Maybe this might help if you are using killer software

Guys, it might be AI suit 3. I am was having the issue, I updated my bios and the issue went away. I did not install AI suit for several weeks and when I did the issue came back after a day or so, but it does not happen every shutdown. Looking up the issue with AI suit 3 brings up many other forums.
