Attempted fixes:- Unplugged all peripherals except keyboard and mouse.

Try setting it to sleep and then immediately unplug those two things as well. That'd narrow things down a little more.

- Disabled "Allow this device to wake the computer" on the network adapter's Power Management tab
*** Here's an odd quirk: After disabling this checkbox, powercfg still shows the network adapter as able to wake the PC. If I go back into Power Management, the box is still checked. Is there another way to disable this? Could this be the issue? Wouldn't it show up in the Event Viewer if the network adapter were waking the PC?

Maybe, try temporarily disabling the network adapter from the BIOS if possible. See if that has an effect.


Also, make sure you're on the latest motherboard BIOS as well.

So something on my network is sending packets that were waking my PC up. Googling doesn't really tell me what this could be. I don't run any servers off this PC. There are lots of other devices (including PCs) on the network -- would something as simple as another PC looking for Windows file shares be enough to wake it up? Is there any way to check this short of removing devices from the network one-by-one?

I assume I can just leave Wake on Pattern Match off, but I'm curious what might be doing this. It's unlikely (but obviously not impossible) that some other machine has some malware.

Anyway, thanks, problem (generally) solved, since I doubt I need Wake on Pattern Match on my gaming PC.

Yeah, something on the network is doing something. It could be caused by many things but using https://www.wireshark.org/download.html might help you find out what's going on.

But if you aren't going to need remote access to the computer then I'd just leave those options disabled.
