PC Turning on by self randomly

[peterpepo]

Hello guys,

 

I am looking for help. My new build (actually it's not that new, it's almost 2 months since I built it) is turning on by itself totally randomly.

My pc specs are following:

PSU: Seasonic X-Series 750 || MOBO: MSI Z97 Gaming 7 || CPU: 4790k || RAM: 2x8GB Corsair Vengeance XMPP 1.3 -> 2133Mhz || GPU: Evga GTX780 SC ACX || SSD: 256GB Samsung 840pro || HDD: WD Caviar Black 2TB

CASE: Obsidian 450D - but I don't think that 'stuck powerbutton' or something like this is causing my problems.

 

The pc boots absolutely randomly, but I have noticed something interesting.

When I am using it regularly, it works just fine. For example, if I use pc in the morning, before work, then it won't turn on, in the evening.

But when I am day or two completely of my house, I return back and find my computer running.

 

I am running windows 8.1 x64. Every possible option in bios to wake pc by hardware (PCI, USB, WOL) are disabled. Bios running in UEFI only mode.

There have been multiple bios updates, since I finished the build, which I was hoping would fix this problem, but no luck, actually I am not sure that this is caused by mobo. I also tried reseting to default bios values, still no luck.

Btw, i am using powerline adaptor from D-Link, as my network solution, just in case it could have something with my problem.

 

So, please help me - to diagnose and ideally fix my problem. I am starting to be desperate, i don't have even idea, where could be this coming from.

 

Thanks

Do you have wake timers enabled in your Power settings?

To be honest this is the first time I heard about computers turning on by itself But Can you check your AVR if your using one that is. 

[peterpepo]

Do you have wake timers enabled in your Power settings?

Yes, they are enabled. But, i am not putting PC in sleep at all. I always shut it down completely. No power led's are blinking, no power consumption, nothing. It turns on from complete shutdown !

Sorry, what is AVR  how to check that.

I am not using one of these.

In your Bios or on your Network settings have you got WOL (Wake On Lan) enabled, It could be a chance something else on your home network is waking the PC. or could be simply something like the connection going stale then live? so somoene rebooting your router or switch? 

 

 

OR you PC is crashing on shutdown and simply recovering to the desktop?

It doesn't seem WOL related to me.

Today, i downloaded Wake On Lan android app to test this feature.

Firstly i enabled in BIOS Enable By PCI /this includes also wake on lan/ and disabled EuP2013. It worked fine, I was able to wake my pc up.

Then i disabled PCI and enabled EuP, which means "network card dead" during power-off state. Then I was not able to wake my computer anymore.

So it seems to me, that WOL disable does it work

 

Pc crashing - I don't know, it doesn't reboot immediately, at all. Sometimes it takes 1, sometimes 2 days since my last usage of computer to boot this way.

 

This article right here http://msdn.microsoft.com/en-us/library/windows/desktop/aa373229(v=vs.85).aspx

In Windows 8, the default shutdown behavior puts the system into hybrid shutdown (S4) and all devices are put into D3. Remote wake from hybrid shutdown (S4) or classic shutdown (S5) is completely unsupported. In Windows 8, NICs are explicitly not armed for wake in both the classic shutdown (S5) and hybrid shutdown (S4) cases because users expect zero power consumption and battery drain in the shutdown state. This behavior removes the possibility of spurious wakes when explicit shutdown was requested. As a result, Wake-On-LAN is only ever supported from sleep (S3) or hibernate (S4) in Windows 8.

Note that in Windows 8, hybrid shutdown (S4) stops user sessions but the contents of kernel sessions are written to hard disk. This enables faster boot.

According to this, default behaviour of Windows8 is to put computer to Hybrid Sleep (S4) state. Is something able to wake computer from this state, at all ? For example windows scheduled tasks, mouse, keyboard, etc ?

 

Also, is there anybody aware of some kind of utility to find out, to which power state did windows set the computer ? In other words: i would like to trace, whether my computer is going to S0-S5 states.

when it boots randomly it loads Windows normally or loads the BIOS-Bios errors?

It boots windows normally.

I come to my computer and windows is booted, waiting for user password.

Do you turn it off at the mains? could litterly be your power settings in bios set to "Power on" after power resume? and somone is unplugging it / replugging it? at the wall i mean!

Nope.

I turn via Right Click on windows logo -> shutdown. 

No unplugging from the wall.

And bios is set to POWER OFF after power resume.

[mark201200]

Try changing The CMOS Battery. Maybe its discharged and after some days it cant Give enough power to the CMOS , so the system boots up to prevent the loss of the bios settings

[Lazmarr]

I have the same problem occassionally OP, it could just be your power from your wall dropping, causing your PC to start itself?

[Tomiking]

After a power-cut when the power returns, some PCs can restart/turn on by themselves

[bmanzzs]

Remount your motherboard to your case and make sure to use all of the risers. It could be shorting.

I might have a solution for you, this has also happened to me, turned my computer completely off, only to find it running in the morning. The culprit was a piece of software from the MB manufacture (Asus) it was some kind of charging app or something, so it got powered on by the fact that there was a USB device attached.

 

If you have a software suite or anything that came from your MB manufacture uninstall it and see if this solves your troubles.

[peterpepo]

Bios is holding it's settings perfectly, no settings loosing or whatever, but I will try this as a next step.

Don't know. Brother has some power supply, different mobo in the same house, working just fine, no booting without reason.

 

After a power-cut when the power returns, some PCs can restart/turn on by themselves

Any way to avoid this ? I am really getting tired of this issue. Can't be PSU or MOBO be faulty, so it "decides" to boot ?

 

Remount your motherboard to your case and make sure to use all of the risers. It could be shorting.

I am using Corsair Obsidian 450d case. There are no riser screws in the package, however all places, where motherboard can raise are higher, so the board doesn't touch the plate. Risers are "embedded" in the case.

MSI Supercharger - some fancy stuff to enable charging of iDevices. I am not using it anyway, and it's disabled. But i will try this as a next step.

 

By now, i tried clearing cmos -> loading bios defaults -> setting my values again.

We will see.. The worst is, that i cannot simulate this. The problem appears totally randomly.

I had to actually uninstall it, I'd give it a try.

Sack,

what was the problem / issue in your case. Was your computer turning on from complete power-off state (S5), or was it waking the computer from sleep ?

[MaxY]

Go through your BIOS settings and check for what has permission to power on your PC. It could be your LAN card, USB Adapter... Many other things. They all should be in the same "category".

[Sargent Mustard]

It's haunted. Call an exorcist.

Same as you, normal shut down, not sleep mode.

[mark201200]

 it's holding the settings because the system boots to Prevent  the loss of BIOS settings. When you are not at home try unplugging the power and after some time (maybe one day) you should check if any BIOS setting is lost, so you can see if the battery is actully dead.

*edit* Also try removing your mobo from the case and put it on a non conductive material. Then wait and see if it still boots randomly.
