I have a rather strange issue with a Windows 7 Desktop. This computer will partially wake itself up from sleep and go back to sleep. When it partially wakes up, the fans spin up, the case lights come on, hard drives spin up, and USB devices receive power for a brief period of time. The displays never come on. After about 2-5 minutes, the computer goes back into sleep. It does this about every 45-60 minutes.
If I move the mouse or hit the keyboard while the computer is in its half-awoken state, the computer doesn't do anything different. It doesn't fully power back up and it resumes putting itself back to sleep after a couple of minutes. Because of this, I can't use the "powercfg -lastwake" command to track what is bringing it up.
However, if the computer is fully asleep (nothing spinning or on), then I have to use the power button to turn it back on. The keyboard will not wake it up, even though the keyboard is shown as a registered device to bring the computer out of sleep (confirmed from powercfg command in command prompt).
I apologize if this is somewhat confusing, but I've been searching around for the past few days trying to find a resolution. I am confident it isn't malware related, as this computer is scanned with Malwarebytes and Security Essentials twice a week (nothing detected in quite some time).
Things I've tried:
Any thoughts? Suggestions?
Thank you ahead of time!

Things I've tried:
Adjusting power settings to turn off hard disks and display after 20 minutes, put computer to sleep after 60 minutes
Disable the mouse from being able to wake the computer from sleep through elevated command prompt
Double checked that the network adapter is not able to wake the computer from sleep
Disabled magic packet wake for network adapter
Any thoughts? Suggestions?
Thank you ahead of time!
