Computer randomly waking up from sleep

[failblox]

I've noticed this problem for a quite a while now (definitely more than a year), where I put my computer to sleep, and a little while later (sometimes a few minutes, sometimes 15 seconds later), it'll wake up from sleep without me moving the mouse, pressing keys on my keyboard, or pressing the power button. The amount of time until it wakes up after putting it to sleep seems completely random. If I remember correctly there were even some times where it would wake up after 15+ minutes of sleeping.

 

Specs, just for the sake of it:

• CPU: i5 3570K
• Mobo: P8Z77-V Pro
• GPU: EVGA 760 w/ ACX SC
• Storage: Intel 335 180GB SSD (C drive)
• Storage: Corsair Force 3 240GB SSD (I have OS X installed on here, but it's kind of broken right now)
• Storage: WD Black 4TB (games, movies, music, etc.)
• CPU Cooler: H100
• RAM: 16GB Corsair Vengeance 1600MHz 9-9-9-24
• Optical drive: I have no idea, but it's an optical drive.

 

If you have any questions about my specs or the problem, feel free to ask. I should note however that I have reinstalled Windows multiple times on this computer. I used to have Windows installed on my Corsair SSD, and OS X on my Intel SSD, but recently I swippity-swapped the two.

Any ideas would be greatly appreciated as this has been really bugging me. Thanks in advance for all your replies

So does it unlock itself and go onto the desktop? Or does the screen just come back on?

 

Either way is it really that big of an issue?

-SNIP-

 

Be sure to check your device manager>network adapters>properties>Power Management> Uncheck the allow to wake. 

 

Most of the time it's the network adapter.

 

 

It can also be windows updates, check it's scheduling and time when it decides to do it's updates.

The screen comes back on and it goes to the Windows 8 lock screen.

And yes, personally I think it is a big deal because I'd save a lot of power when the computer's in sleep rather than when it's running, and sometimes I do my homework on the same desk, but I won't need my computer for that particular piece of homework so the fans running can be distracting at times.

To add to this, in the Network adapter properties, go to advanced and see if you have a setting like "wake up capapibilies", "WOL", "wake on magic packet" etc... and turn those off.

 

Edit: If it's not the network adapter then try this to find out what's causing it-

Thanks, I think this fixed it

Those were checked. I remember checking them a while back when I was messing with WOL. Just unchecked them now. Thanks

Hi there failblox,
