Sabertooth Z77 System won't shutdown, fans still working

[OGZ_Prescott]

Hello,

I have an issue that I cannot seem to find a solution, I pretty much looked everywhere and now I am starting to ask questions myself.

My system won't shutdown after I prompt Windows to do so. The screen goes blank and the system will just keep on running like nothing happened. I have to push power button for 5-6 seconds to force a shutdown.

Here is my system info:
Intel i7 3770K
Noctua NH-D14
Sabertooth Z77
Corsair Vengeance Low Profile DDR3-1600 RAM
MSI GeForce GTX680
Corsair Performance Pro 128GB SSD
Western Digital 1TB Caviar Green
Corsair 400R Case
Seasonic 850Watt

Some more info about the issue:

System is on Windows 7 x64, fully updated both OS and drivers.
Bios is updated. Tried both the latest official BIOS as well as the unreleased one that I found in this forum and the others.
Bios is set to default values. (Default values meaning 1333MHz on those 1600MHz sticks tho, is this normal?)
System temperatures are around 30-35 degrees celsius on idle. 60-65 degrees celsius on load.
Fan overtime ON/OFF doesn't make a difference and I seriously doubt that It should affect anything else than the small fans on the motherboard.

Are you running any applications that are java based?

I think i have a similar issue with the same board.
I sometimes find my comptuer with this black screen when I wake up in the morning.
My thoughts are that its gone to reboot after an automatic update and hung.
The only way to get arround this is to hold the power button.

Weird thing happens when I do this though, the USB keyboard stops working during the POST. So I cant get into the BIOS.
The only way to fix this is to unplug all USB devices while the computer is off, then plug them all back in, quite frustrating.

I have the latest BIOS.

they easy fix is turn your power supply off and unplug it from the wall let the mb drain for about 5 min. something on the mb must of hung.

I am having the same problem as the original poster. Also on a Windows 7 system (64-bit), also with the latest BIOS. If I shut down my system either from Windows or from the power button, the operating system shuts down but all fans continue to run and all my case LEDs stay on. Even I choose to put the computer into Sleep mode, the same exact thing happens.

I've looked through the BIOS settings and can't find anything that changes this behavior. Currently in order to shut down my computer, I have to turn off the physical switch on my power supply.

Also, this isn't sporadic. It happens reliably every time I shut down my machine.

[microc]

you have to turn the power supply off and let it drain...then it should shut down right...some people have said it was the nvidia 30x drivers.

Hello guys I see the OP has not posted back as yet about the JAVA thing and it is not an issue for any of you.

Could you please confirm if your system is running at defaults, or test this for me. F5 in bios to get your system back to default. And then F10 to save and reboot.

I can not duplicate this currently so I wonder if it is some kind of bios setting or as has been suggested something that a nVid driver may be doing. Not sure how that would work if the system was powered off but you never know with electronics. :)

[dimitryi]

I am not using an nVidia card, so I don't think it's nVidia drivers alone. I am using an AMD Radeon HD 6950 and the latest 12.4 Catalyst Control Suite. Here's my setup:

Motherboard: Asus Z77 Sabertooth (BIOS 1015)
Processor: Intel i5-2500k
Memory: Corsair Vengeance 1600MHz - 16GB (2x8GB)
GPU: AMD Radeon HD 6950 (Catalyst Suite 12.4)
Storage: Crucial m4 128GB SSD and Western Digital Caviar Black 640GB SATA HDD
OS: Windows 7 Professional 64-bit

I will try fully draining the motherboard's power today. I shut off the power supply switch every night, but I'll unplug it also and let it drain for a bit. I also haven't done any overclocking yet, so my BIOS settings should be at default, but I'll set them back to default and check that out also.

Over on Overlock.net's z77 owners thread (http://www.overclock.net/t/1246595/official-asus-sabertooth-z77-owners-thread-club) there are a number of people with this shut down problem.

[dimitryi]

First test: Drained the motherboard power. I shut down Windows, switched off the power supply, and unplugged the power cord for ten minutes.

Result: No change. I powered back on after ten minutes, let Windows load up fully, then shut down again. All fans kept running and case LEDs stayed lit up after shutdown.

[dimitryi]

Second test: Returned the BIOS to defaults. Went into the BIOS (v1015) and pressed F5 to return the BIOS to optimized defaults. Saved the settings and exited with F10.

Result: No change. Windows booted up fully and then I shut down again. Fans stayed running and case LEDs stayed on after shutdown.

[HiVizMan]

Thank you sir.

[dimitryi]

Third test (suggested over on Overlock.net): Went into the BIOS and made sure the following were disabled: Fan Overtime, Intel Rapid Start, and Intel Smart Response. The latter two were already disabled by default, but I turned off Fan Overtime.

Result: No change. Windows booted up fully, then I shut down and the fans kept running and the case LEDs stayed lit.

the only thing i changes in my bios is im running the xmp profile. on the ram. I did not load any of the asus software for windows. I got the board to do the reboot thing twice the second time was when only some of the mb drivers were loaded from a clean install of windows.has anyone that has the problem now gone into windows device manager and checked that all the drivers are loaded. the one that people miss is that new msi one from intel. that gives that missing pci device 0004 error in device manager??

Good news everyone!

Thanks to a suggestion over on Overclock.net, I just resolved the shut down issue on my computer. I just tested and confirmed that now when I shut down, the fans shut off and the case LEDs shut off.

To fix it, I had to reset the CMOS jumper. That's covered on section 2-14 of the z77 Sabertooth manual if you're not familiar with how to do that. The only catch I ran into is that when I reset my CMOS, it re-introduced a DRAM problem that I ran into last week and had since fixed, where my computer would not get past POST. To fix that, I had to use the MemOK button on the motherboard, which downclocked my memory from 1600 to 1333. I've been told that's not unusual because I'm using a Sandy Bridge processor.

But, once the DRAM issue corrected itself, now when I shut down, everything shuts down. Give it a shot if you're having the same issue.

[HiVizMan]

Very happy to hear that you are sorted.

Below is an explanation for those who are not sure what a Clear CMOS will do or is.

A CLEAR CMOS will clear all settings from your BIOS, as it is effectively resetting your system to the factory defaults. This will mean you need to go back into BIOS on the next reboot and set up your system once more.

Hello all. After countless hours of searching, I thankfully made my way to this thread. Could you please help me fix my shutdown problem as it is almost exactly what you were experiencing before.

Build Contents:

Intel i7 3770k 3.5GHZ
ASUS P8Z77 V Pro Motherboard
OCZ 850 W. PSU
WD 500 GB
Windows 7 64 bit Professional

This is my first computer build, and I just put it together last night. I spend the whole day and night putting it together, and it worked great. Today, it had some issues shutting down, - exactly as described above.

I ended up reformatting a brand new hard drive 3 times to try and solve the problem, - yet this did not help. I updated all the updates from Windows Update, and updated all of the drivers on my desktop. Oh, and yes my copy of Windows 7 64 bit Professional is genuine with a valid verified cd key. I am currently running integrated graphics waiting for my graphics card to arrive in the mail.

This is what happens when I go to shut down:

1. Click shut down button.
2. OS moves to "shutting down logo page w/ revolving circle."
3. OS turns off, screen turns to black.
4. I peek inside the tower (I have the case panel off) and I see that the CPU heat sink is still revolving, the motherboard light is still on, and all fans including the CPU heat sink fan are still working.
5. I am lead to believe that the signal is not being sent to the PSU from the motherboard telling the PSU to turn completely off.
6. Thus, the PSU is still on.

:(

Please help me, I invested over 1200 dollars into this setup, I really want to make it run as it is supposed to.
I see above that Dimitri modified the CMOS jumper. I have no idea what that is, and further I have no idea how to do that. It is almost important to note that we have different motherboards. I have the P8Z77 V Pro, although I am open to any suggestions to help me get my computer booting down as it is supposed to.

I believe that everything else is working 100 percent as it is supposed to, the only thing is, the shutdown will not complete itself as the steps indicate above.

I beg of you, please help me. :( I will check this thread hourly for a response. Please take a few minutes to help me, I am most appreciative of anyones support and help.

Thank you,
Emmanuel

If you read the manual that came with your motherboard you will find information on how to clear CMOS. It will be listed under "Clear RTC".

Sorry for the late reply.

This issue is not solved, I've reformatted the machine to be sure that it wasn't a Windows(or Java) issue however I noticed that the system will lock down on safe mode on the shutting down page but this time the screen won't go to sleep. The normal problem that I've told you before still exist.

I've sent the whole system to my retailer's technical support, they told me that they need to send the motherboard to replacement and that they've encountered this issue before with Asus Z77 Line and Asus knows about this issue (I am not really believing that tho) and therefore waiting for ASUS's instructions. They hope to have a modified BIOS so that they can fix this issue, but I am not convinced.

Before I sent the system to my retailer, I've tried the 1015 BIOS but no improvements. This CMOS reset thing supposed to be happening while you flash BIOS too, right?

Another thing is about the GTX680 which may cause problems, I've tried older/current/beta drivers as well as I've tried my old GTX460, which proved not improvements.

Hopefully I'll be getting my system back soon whether this issue is solved or not while it is not a life threatening issue, but it is disgusting to have an issue like this with a system that costs a fortune.

I managed to flash the CMOS jumper as suggested above, and my problem went away!

For future reference, for those who might find this thread in the future, the instructions say to pull the cap from the CMOS jumper from pins 1 & 2 and place it on pins 2 & 3 for 10 seconds. Then remove the cap from 2 & 3 and place it back on 1 & 2. Please make sure to first power down the PC, turn off the power switch to the PSU or unplug the power cable before doing this.

I am using an ASUS P8Z77V-Pro board and this worked for me.
For those you using the same P series board, the instructions for how to reset the CMOS jumper can be found on page 2-17 of the manual that came with the motherboard.

Thank you all for your help, and a special thanks to this forum board and thread for allowing me to fix my problem.

Good computing and happy gaming!

When i using Windows 7 it shut down perfect no problem...but when i use Windows server 2008 R2 it will not cut off power when i shut down, my light and cpu fan keep running then need to use force shutdown by pressing power button...maybe is the HDD because my windows server 2008 R2 i was install on other HDD....or u can do the reinstall ur OS then do the test,,,

[Motherboarder]

Same problem for me too. Not solved. ASUS Sabertooth Z77, PSU is a "Super Flower SF-500P14FG, 500Watt, 80Plus Platinum, Fanless", Operating System is Windows Server 2008 (not R2) Enterprise x64. I know the OS is not officially supported (no USB3 driver) but it's Vista generation, so not too old and I don't have any other/newer Server license.
No Java installed. Restart works without problems. Shutdown goes black screen, but doesn't turn off. I'm not 100% sure, but I think initially shutdown was working. Not sure what I changed since then. I did install the Thermal Radar tool, but no other tools, not even the Intel Fast Response/Rapid Start/whatever things. I upgraded to latest available BIOS (should I try an older one again?).
CMOS reset does NOT fix problem.
Any suggestions? I have full electronics equipment if you want me to measure something. How should the PSU be directed to power off? I need to know if the PSU (is new) is faulty or the motherboard or if it's a config problem.
I can't have this server offline for some days.
