Desktop turns on by itself after shutdown windows 7

[shimspp]

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!

I have this same problem with my z87 pro motherboard. I am a tech and know ....

Well apparently you don't know to read the SOLUTION (in bold GREEN) that was solved two years ago.
Instead of continuing this NECRO POST (2 years wow!) maybe you should have followed the solution.
The issue is the INCLUDED SOFTWARE / Drivers the WIFI element will "WAKE ON SLEEP" (you do know what that is on NIC/Wifi is right?) even if you believe you 'shut down', the negative current (since you know what a Ohm Meter is) keeps electrical devices alive, and thus the WIFI keeps in a SLEEP state because you have power connected, though you 'shut down' Windows (software).

The pointed out solutions demonstrates that just because 'WINDOWS' is off doesn't mean the Hardware isn't still 'alive' with power. The reason why your BIOS stays as you set it, the reason why your TIME is always correct, etc.

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.

Click the power icon in the bottom right of Windows. Select More Power Options, then choose "What the Power buttons do" and make sure they are set as you wanted them. You sound like your in Sleep mode because someone presses the powerbutton then wakes up when one of the software elements (Antivirus, Adobe, Chrome, whatever) needs to do something (update, get patches, check the drive, etc.) so it will wake up the computer to do the takss.

Remember alot of tasks get pushed to off times so they can be done then get in the way of the user experiance during the normal operatiosn.

I've checked that power option to and its on shutdown. I know its not on sleep mode because on my case it has LEDs that blink when the computer is on sleep. Also it says Shutting down when i press the shutdown button. I do know updates, and patches do happen but i never had a problem of the computer turning itself on to do those updates. Also it doesn't even update when it turns on because i haven't logged on to the computer yet.

Fetpower- I had the same problem with the computer turning on spontaneously as well. If you look down at my previous post, I list what I did to trouble shoot it. Eventually I disabled the ASUS WiFi [I think it was in the BIOS] and that solved the problem. It has been 9 mos without a problem.

Ok, I had the same problem. I tried the suggestion of enabling the "erp ready" option in the bios and voila, problem solved. My system no longer turns on by itself anymore. Previously it would turn on by itself after 5 hours of a complete shutdown. Very annoying issue, thought I was imagining it first time it happened but after enduring it for days I realized ya this is a problem that needs to be resolved. Hats off to the guy on these posts that said enable the "erp ready" option.

Hello all,

I've been having a similar problem on a brand new z87 pro. I have also suspicions that this is due to the wifi antenna as limited testing that I have done seems to do away with the problem.

Can anyone else confirm this?

Q.

I have a similar issue. My Asrock H97 Pro4 suddenly won't shut down. It just starts back up, no matter what I do.

I checked the BIOS and wake from lan is disabled. I have no WiFi on my board.

It all started when I pressed the power button to shut down my computer, because I was too lazy to sit back down to close it properly.

Now it is on 24/7, although it does go into deep sleep and powers off. I just wiggle thje mouse to wake it up.

Anyone know of a different way to shut off properly?
