After an arbitrary, but small amount of time, my computer wakes back up after going to sleep. I have attempted desperately to solve this issue, short of contacting any official support or re-installing Windows. I do not remember the problem occurring when I first installed Windows, but I am not sure. The machine is self-built running Windows 8 Pro.

These are the events that occur with sleep (in order):

I can provide any other system specifications upon request. Many people seem to be encountering the issue with Windows 8, with various solutions failing to resolve my issue. My hunch is that it is a driver or motherboard issue, any troubleshooting help would be greatly appreciated.

EDIT:

In a further attempt to solve the problem, retrieving a Power Efficiency Diagnostics Report with Powercfg –energy during an induced sleep/wake cycle unsurfaced the following "error:"

System Availability Requests:System Required Request
The program has made a request to prevent the system from automatically entering sleep.
 Requesting Process \Device\HarddiskVolume4\Program Files\Windows Media Player\wmpnetwk.exe

(Full report)

Disabling Windows Media Player Network Sharing Service in Services has so far not relieved the issue, as I still find my computer awake moments after I sleep it.

Through trial and error I finally found disabling the network adapter from being able to wake the computer under Device Manager immediately cured the issue. My PC no longer wakes up from sleep unexpectedly!

I hope that you mean it no longer wakes up from sleep when you don't want it to; be careful what you wish for! –  PeterT Feb 26 '13 at 23:14
    
@PeterT Thanks... fixed! –  Andrew McKinlay Mar 24 '13 at 19:09
    
This does not work with me. –  paulo Mar 12 at 9:53
    
@paulo Make a separate question with more details and diagnostics. –  Andrew McKinlay Mar 12 at 14:47
