Windows 7: OS keep randomly awaking from hibernate

I'm also getting this problem. "Wake source: unknown". Haven't been able to narrow it down. The machine is waking itself up about every 20 minutes.

Windows 7 Ultimate 64-bit

I have three machines on my network which run W7 Ultimate 64-bit, all installed off the same install disk, so variables are narrowed down. Two machines don't have the automatic resume problem, one does. I wonder if it's hardware related, though even there my systems are not that different. My machine based on an Intel DG33TL mobo works like a dream, but my machine with the later Intel DG45ID board has the problem. I've installed all latest drivers & bios.

Those others who have the problem, what mobos are involved?

I'm pretty confident it's not the network (or the network adapter) that's causing the problem, because when I disable the adapter I still get the unwanted resumes.

Windows 7 Pro 64bit
This solution worked for me

Poking and prodding around I found this toggle.

Control Panel
System & Secutiry
Power Options
Change Plan Settings (for the one selected)
Change Advanced Power Settings
under Sleep
Allow Wake Timers
change it to Disable

I changed it two weeks ago and haven't had an unwanted start-up since.

I've messed with other things, but I'm pretty sure that's what did it.

Except that I bought a new DG45ID having thought I'd exhausted all other possibilities and it doesn't wake itself up, even with the wake timers still enabled.

So that tells me it's unlikely to be related to the wake timers, but I probably also didn't need to buy a new board because you fixed yours somehow Anyway, we're both in a better place now
