I just built a new desktop but for some reason my computer keeps turning on by itself at random times. Everytime i turn off the computer and i come back later it is on sleep mode. (because it turned on and went to sleep). I know its not somebody pressing the power button because i saw the computer turn on by itself in front of me. Also it is sporadic, sometimes it turns itself back on after 10 mins sometimes 30 sometimes takes hours. I've checked all my bios settings and turned off Wake-up Lan settings and such, don't have any scheduled defragment or updates, so i can't figure out the problem?? The only thing it can be is faulty case or motherboard. But i bought a Rosewill Thor V2 (case) and Asus z87 Pro (mobo) which are pretty decent products. I was wondering if anyone had problems with faulty power switch with this mobo or case. Or if anyone knows what setting might be turning my computer on for no reason. Thanks!
 
Solution
Hey i just built my PC with the Z87-PRO. it has happen to me also. I notice its a problem with actually the Asus AlSuite III. When i got my board installed it was operating perfectly fine. Then the next day I install the softwares on the CD ROM included. After that after shutdown the computer would just boot up randomly. I checked everything to make sure it wasn't being wakening by a wake on lan, controller, task sch. After all that i just restored the system to the point in time where the Asus Alsuite III wasn't install and it works fine now. im going to go only and download the upadted AlSuite III from there to see what results i get.

P.s Is anyone having Wifi problems with the board for online games, there is always frequent lag...
As the problem occurs from a full "power off" state, it has to emanate from a BIOS condition - the OS cannot possibly have any bearing on it. The ErP change to "Enabled" (in "Advanced - APM - ErP") ought to stop it happening, as the default condition for the BIOS is to leave the WiFi module "live" even when the OS is shut down, ie fully shut down (S5 mode) or hibernated (S4 mode), not put into sleep mode (S1 - S3). The ErP change shuts down the WiFi module completely, leaving the motherboard unable to respond to any external event exept for a push on the power button.

It would help if motherboard manuals were not just lists of available settings (many of them completely obscure except to a bios engineer), but explained what the options are actually for, then perhaps more people would be able to work out for themselves how to cure problems like this one.

Tom Tancredi - I notice you haven't got a Courtesy Certificate listed in your qualifications: this is a Help forum, you know. Who declared the thread "DEAD", as you so loudly state? I can't see a gravestone anywhere on it ....
 
The question was back in July, the answer came down to hardware (as I said) then became the discussion on the BIOS on the mobo into the first week in August, which put the onus back on ASUS that the subject would need to be taken up with them (not here in the forum). Then a solution was informed on Sep 1st, that on a 'CLEAN' install all was fine till Asus Alsuite III (part of the drivers installs) was installed then all issues happened. A regression back to 'before Asus Alsuite III installed' again rectified the issue.

So yeah, I thought (reading the whole thread from the beginning) it was 'DEAD' and everyone posting to it since then been 'hey me too' statements not "No Asus Alsuite III isn't the issue it is.... " ongoing different discussions. SO yeah, the answer was posted and people are just 'adding' no real discussion just 'me too' posts.
 
Actually, Tom, the thread is about mysterious startups after shutdown, and the AI Suite installation/uninstallation was only part of the answer. The truth is that AI Suite can be left installed on the computer (with all the additional utility that it brings), but ErP also needs to be enabled to stop the unwanted startups. This problem also existed on the ASUS Z77-Pro motherboard, and ASUS should have at least added a note in the latest manual to warn users about the required settings but, as I indicated earlier, manuals are not the strongest selling point of MB manufacturers.

I still don't see that it's for you to judge that a topic is dead, when other people are still finding problems which aren't conclusively solved by earlier answers, regardless of how many previous posts you've personally made or how many badges you've got. Acting like a school prefect isn't very edifying, and attempted self-justification afterwards isn't very pretty, either.
 
You asked a question Dave, I answered it. You may not 'like' my answer, but that doesn't mean I was attempted self-justification. The TH forums are to help solve a issue, not to ongoing endless thread about something so people can keep saying 'me too' or "screw that' or whatever else. When a thread rehashes 6 months later and still the SAME solutions is still provided (it comes down to WLAN Wake-up, be it BIOS, OS or application AI SUITE III) and the issue should be over since.. as you said

"The truth is that AI Suite can be left installed on the computer (with all the additional utility that it brings), but ErP also needs to be enabled to stop the unwanted startups."

A Alternative solution to removing the AI SUITE III. Great. DONE.

What more could be said? REALLY?
 
Copying a reply to similar thread on
http://www.overclockers.com/forums/showthread.php?t=699445

Seems it is an ErP issue that is set in the BIOS - I didn't know what that was until I read the following very useful thread.

"... Enabling ErP will disable waking from full power off state with anything other than the power switch. With ErP disabled, it's possible to set your computer up to turn on with a click of the mouse or with a keyboard, or with a packet sent to the NIC. It has no effect on waking from sleep. The purpose of it is environmental. When powered off, your motherboard makes sure it has just enough power to receive a power on signal from it's connected devices. if ErP is enabled the motherboard allows itself to full power down."
 
I first tried to change the wireless controller setting MS CLIENT power management option as mentioned above. THIS DID NOT WORK.

2. I enabled the ErP in the bios as suggested here. I am using my wireless so I did not want to disable the Asus suit. Enabling the Erp in the bios WORKED! no further problems and I do not see any performance issues. Thank you for the fix.




 


 
Hi, I am a newbie here and just built my PC with the Asus Z87 Pro and I have exactly the same issue. I am posting this just to prove it is still an ongoing problem. I will try the ERP route first, but I also have an issue with Windows 7 x64 not shutting down if there is an internet connection. If I disable the WiFi connection, Windows will shut down very quickly.

Anyone know if this is a related problem or something I am doing wrong. I usually use and wired connection to the router not WiFi.
 


I wish I had an answer - occasionally my machine shuts down and fully turns off, but most of the time it shuts down from Win 7 and leaves the fans running and case light on - or sometimes it just re-boots again as soon as it has shutdown - like a 'Restart'. I have enable ErP - done just about every thing that makes sense in the BIOS but this is what I am left with. Only solution I have (not much of one) is that I have to sit by it and wait until it has shutdown and just as it starts to re-boot I turn the power supply off from its own switch as I just can't trust that it stay off. Bloody crazy really.
 
Northspoon, if you have malware or a virus still running in the background that is using the WIFI (or whatever Internet connection you have) it will prevent the correct shut down of Windows (this thread is about sudden START UP in the middle of the night AFTER a POWER OFF, NOT stopping a Shut down). There is many threads on this, but basically

Do not use Microsoft Security Essentials, it rates lower as compared to other AntiVirus (AV) software that is free. Uninstall MSE and go to www.filehippo.com, download AVAST! or AVG and do a full scan of your computer.
Donwload and run a full scan with Malwarebytes, malware is different from viruses, and isn't normally detected by AV solutions.


Dionysuss: Your situation like northspoon is OPPOSITE to this thread. Your issue can easily be 1) overheating (see the many threads related to sudden shut downs and reboots) 2) AV fighting a Virus/Malware and causing the OS to 'crash' (reboot) 3) Bad component such as HDD which stores the code provides bad data causing a crash, etc. etc.

As for " Win 7 and leaves the fans running and case light on" that is asymptomatic when you press the power button you hit it in the manner for 'Sleep' or Hibernation, which does NOT power off the computer, but puts it in the mode to restore exactly as you left it (different program windows open, etc.). This can be checked by clicking the power icon in the tray, select more power options, by default the power is set for laptops as balanced so clicking Show Additional Plans will let you select HIGH performance for your desktop, then clicking the different options on the left panel (i.e. Choose what the power buttons do) and setting them to your preferences nomally eliminates the issue for users.
 


Hi thanks Tom for that detailed response. The machine isn't overheating - the CPU running at 22 degrees and MOBO at 18 degrees. I am using McAffee and the HDDs are being monitored with Diskkeeper - I will try the Malwarebytes advice you have given. My usage is how it has been for the last many years - when I shutdown the machine I am shutting it down from Win 7 and not touching any buttons on the case. I am not getting system crashes nor does the machine re-boot on its own, in fact it runs beautifully - the only problem tat I get (which the more I read it seems a kind of common problem for this Asus Pro Z87 MOBO) is that when I shut it down from Win 7 that it sometimes shuts down properly, but more often than not either shuts down fully but then immediately starts to re-boot or shuts down and leaves the fans running and light on.
 
Hi, I have recently built a pc for a friend of mine. It turns on by itself at random times with no good reason. The MB is ASRock fm2a88x extreme4+. As one can see it has nothing to do with Asus or Intel chipset. There is an option in the BIOS for Dehumidification that according to the manual turns the pc on to prevent humidity, but the option is disabled. The wake options are disabled too. The only thing in common with the other guys here is that i have installed a PCIe WLAN card on the computer. So when i have time i'll check the ErP solution and see what happens. It would be great if someone provides other suggestions though.
 
The wake options is not in BIOS but under the actual Networking device Properties (Both NIC and Wireless). Further as I noted is the default Windows Power settings which is set for Laptops even if installed to a desktrop. Again check both theses power settings as well as under the Device Properties for ALL network devices installed in the PC.

Additional to this download and run a full Mawlwarebytes scan, don't use Microsoft Security Essentials as your AV but install AVAST! or AVG instead and again run full scans (all are quickly downloadable from www.filehippo.com)
 


 
I am very low tech. I have a cybertron gamng tower. Its hooked up by ethernet. It tries to turn on. Has not always done this. Worst part is it makes a race car reving up sound when you turn it on. Has scared the geebers out of me, especially in the middle of the night. I am looking for answers too. Sorry but I am not up on computer language. Have to explain simply. Thank you!
 
I experienced a similar problem of spontaneous start-up with a Z87 deluxe quad board. I turned off the wake up feature for the network adapters [including the onboard WIFi device], mouse and thunderbolt, checked for scheduled tasks and updated the BIOS. None of this helped, but I finally fixed the problem by disabling the onboard WiFi device in the BIOS. [Advanced>Onboard Device Configuration>WiFi Controller] The on board WiFi device has other issues as well- for some reason it can't connect to the Adobe Update server for CS6, a known issue described in other forums. I hope this helps others.
 


also just built a comp with asus z87 pro. didnt experience this issue until i installed asus suite 3 and all its drivers. i saw alot of people say it could be an issue with wifi go so i uninstalled it. if you go to programs and features, and try to uninstall suite 3 it will ask you which drivers to uninstall, uninstall anything to do with wifi on there (you can download the seperate wireless driver for your comp from asus website if you need it to keep wifi working). I also uninstalled inetwork control and i went an hr without the comp turning back on. (knock on wood).
 


I am sorry but that is totally untrue. A Wifi Device can't "select" a single website / server of ONLY one software to NOT connect out of ALL the products the maker has, of all the websites/ server that exist. That would be ONLY true in the case of FIREWALL .In order for websites (WWW) to mix up data with emails (SMTP) and not interfere with someone else's BF4 data each software uses a SINGLE Internet Port (65K in all) to keep each type of data traffic separate from other data traffic. So on port 80 (WWW) would the webpage data be sent, as compared to email on Port 110. Depending on Adobe's CS6 server configuration (most use Port 80 like websites) could be blocked by your firewall (software?) installed on YOUR single PC.

Of course the more obvious answer (after a simple Google search) is the flawed programming by ADOBE on CS4 thru CS6 which can't differentiate between the built in Virtual Wifi Adapter, and the actual REAL Wifi used (https://forums.adobe.com/message/4917352 http://helpx.adobe.com/creative-suite/kb/error-update-server-repsonding-cs4.html) that again demonstrates the issue isn't as your asserting, which is IMPOSSIBLE, for a hardware device to be selective on what it will or wont' block, down to a single software product.
 


As noted SEVERAL TIMES IN THE THREAD (so you don't need to keep repeating the same thing OVER AND OVER) IS

DO NOT INSTALL THE ASUS SUITE, if your using the WIFI. You can check and see if there is a UPDATED ASUS SUITE, but the one listed here several times has a SOFTWARE FLAW, your WIFI WORKS PERFECTLY FINE.
 
I do not know how much it can be related with this but maybe you should check if everything is ok with your Task Scheduler. In the past I had some similar situations so maybe somehow there is something wrong. Also check THIS tutorial for automatic shutdown of windows 7 (of course you will just remove task for automatic Turning On option if it exist there).
 


Tom- you seem to know a lot about this subject [a lot more than me]. All I know is that since I disabled the ASUS WiFI and plugged in an Apple Airport, I can update Adobe CS4 and my computer no longer starts spontaneously.
 
I have this same problem with my z87 pro motherboard. I am a tech and know for a fact my pc is not in sleep mode. It is fully off. I have my power options set to never sleep and the power button to turn off. all bios setting are set to never wake up. This has been happening right from the start. At first I thought maybe sleep but nope, I seen my system turn on 6 hours after I shut it off. The power switch is not intermittent because I checked it with an ohm metter. I live alone so no one is turning this thing on except maybe ghosts and I don't believe in ghosts. I fully believe there is a defect on the mobo where a parallel circuit is shorting out the power switch traces to do this. I sent a ticket to Asus so I await their response. In meantime I now additionally turn off the psu switch to prevent this. This is by far the weirdest thing I've seen in 20 years and have built many systems with Asus mobo's.
