Maximus VIII Formula Shutdown but fans still running

[Ultracer]

Dear all,

I'm currently experiencing this problem where once clicked shutdown:

• Windows do it's turn off things.
  
• Monitor off
  
• Mouse and KB light off
  
• But mobo lighting and cpu fans keep running
  

I will have to press and hold the power button to turn off the system. Once it off, turning it on again will NOT give any Windows error.

Can anyone shed some light on this issue. It's frustrating :(.

Thanks.

All right

Yeah if all was well before updating the bios try reverting back to bios version 1504.

Also check in device manager for any unknown devices or yellow triangles.

[davidpiot1974]

Device manager is clean.

I am going back to the previous BIOS. and we take it from there.
let's hope it does something good and i do not have a faulty MB.

Are there other people out there with this issue?

[Nate152]

Sounds good,

Give us an update after reverting to 1504.

[davidpiot1974]

Ok I will.


in the meantime i got an answer from Asus.
A bit strange that they think the blame is on the PSU ??? it's a brand new one i have. and it worked like a charm with my old p6T deluxe v2 MB


Dear mr. Piot,

Thank you for your email.

Corsair PSU's are known for these kind of problems as they have specific power functions.
And example of this can be found on the following website.

If possible I would like to ask you to test this with a different PSU.

I hope to have informed you enough.
Ik hoop u hierbij voldoende te hebben geinformeerd.

Kind regards,
Vriendelijke groet,

Asus TSD.

It would be something to try if reverting to 1504 doesn't help.

[davidpiot1974]

Reverting to MAXIMUS VIII FORMULA BIOS 1601 did not help.

But before i did a revert I noticed that the pc did a complete shutdown.
Problem is that he is not doing that all the time 2 out of 10

This answer to this problem eludes me.
This must be a BIOS problem, i can not imagine that my Corsair PSU (200€) is not up to the task.

I am going to present Corsair the feedback from Asus and see what they have to say about this.

This would actually be a feature of the motherboard, not sure why they told you this.

Please look into your power options.

For me this was Aisuite 3 issue, after uninstalling it my comp started to shutdown perfectly. If you have that i would try removing it and put bios on default settings. You can do overclock manually and better after you verify the issue is gone.

Hi people,

I admit, I don’t have a ROG mobo (went the black and white route with a Z170 Pro), but I have (had?) the exact same problem. Windows 10 would not go to sleep properly. Or restart. Or fully shutdown. Whatever I tried, the fans (both my CPU cooler and all the chassis fans) kept spinning until they got fairly dizzy. I tried disabling fast boot and ERP in BIOS (no dice) and changed a lot of Windows settings (hibernate off, disable fast boot option in Power settings, et cetera). But nothing worked. Bear with me, because here is the ‘however’.
However (trumpets, flutes, lutes, bit of harp): you could try going all old school, by executing a command line shut down. Like so:

%windir%\System32\shutdown.exe /s /t 5

Where t 5 is just the number of seconds before shut down. This actually works for me.

I can also get the PC to restart properly by using

%windir%\System32\shutdown.exe /r /t 5

For sleep, run

C:\Windows\System32\rundll32.exe powrprof.dll,SetSuspendState 0,1,0

but make sure to disable hibernate fully first by running the following command as administrator from a command prompt:

powercfg -hibernate off

There. All set. No more spinning fans.

Is this the ultimate fix? Nope. But it solved my spinning fans problem perfectly. And it works all the time. It might save you a lot of hardware diagnostics hassle and/or a RMA.
This issue aside, my pc runs so well, I really don’t want to screw around too much.

For ease of use, you could just add shortcuts to those options on the desktop.

Hope it helps you out a little.

Just for good measure, these are my system specs:
Asus Z170-Pro
Core i7 6700k @ 4.4 Ghz
be quiet! Dark Rock 3
EVGA SuperNOVA G2 750 W
2x 8 GB Corsair Dominator Platinum DDR4 3200
MSI GTX 1080 Armor OC @ 1733-1872 MHz
Samsung 850 EVO 1 TB
NZXT H440 New Edition case

I'm experiencing this issue on my VIII Formula....maybe if we complain enough here on the forums, ASUS will get tired of it and fix it with a new, updated BIOS.
