So I have recently installed a new motherboard (and fresh install of Windows 10 Pro x64) and have been having strange sleep behavior since. My computer is set to go to sleep after 1hr and my keyboard/mouse fail to wake the computer back up and seem to be not receiving power in general. So when I press the power button on my tower, the fans start up, etc, but my monitors don't wake up, my KB and mouse still do not receive power and are unresponsive.
To get my computer to wake back up, I have to hold the power button down until my computer "turns off" and when I power the computer back on, it boots back up into Windows as if it were coming out of sleep, and not a fresh boot (all of my processes/programs are still running, etc.)
At first I thought this was a BIOS issue, but I have tweaked BIOS settings and cannot seem to get anything to work, and so I feel like maybe it's a setting in power-saver, etc.
For reference, my motherboard is an MSI Z170A M3 (1151). I can see that there are a ton of sleep-related issues with Windows 10, but couldn't find a thread specifically pertaining to my issue.
Thanks!
Try turning fast startup off. Might be relevant.
Hey, thanks for the suggestion! I went into my BIOS and neither "MSI Fast Boot" or "Fast Boot" were enabled. I took a few pictures of the BIOS config and of the power-related options, and attached them below.
Hi, er-- sorry, not thinking of your BIOS - this one - people sometimes find problems with some devices with this enabled (see bottom):
Oh, my bad. It doesn't look like I have a fast boot option in my system settings.
You need to click ..... are currently unavailable.
Right, all that does is allow me to edit the grayed out "sleep" and "shutdown" checkbox options under "Shutdown Settings", and does not reveal any additional hidden settings.
EDIT: Although the fast boot option doesn't appear in the system settings, I was able to locate it's supposed registery key under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerPower. It was enabled, and after disabling it, I tried waking up from sleep and it didn't seem to fix it.

Ah, ok, you haven't enabled hibernation, which reserves the disk space- which means you don't see the option so it can't be that that's causing the problem. QED.
There's a similar thread here, no definitive solution:

Best search the forum and look for solved threads on sleep. Sorry can't help more..
As for your devices that won't wake your PC, they need to have a Power Management tab in their driver Properties (in Device Manager) to be able to wake the PC.
Try this to list all devices that can wake your PC from a command prompt
POWERCFG /DEVICEQUERY wake_programmable
and
POWERCFG /DEVICEQUERY wake_armed
to find currently enabled devices
