Windows 10: Dwm.exe and others crashing on wake - kills pc - please help!

Hi guys, I've encountered a new issue (itself a variation on an old one I thought was gone) on Windows 10 Creators edition and could use some ideas.

In short, sometimes, very occasionally, when I wake the PC up from sleep, everything gets going except the monitor. It stays in sleep and I am forced into a restart to get it going again. It's a kind of black screen without the screen actually being on.

After some huffing and puffing I seem to have isolated the culprit to either dwm.exe, lockapp.exe or logonui.exe - they all crash when this happens (via event viewer), suggesting the normal signal to monitor simply isn't happening or is being blocked because lock screen and visual apps have broken down.

I Googled it and it is a known issue, so at least it's not just me, but is there any fix or remedy?

I disabled PLL overclock in the BIOS (no idea why), I disabled auto source selection in my monitor, and I've changed the DP2 port my monitor plugs into on my 1080Ti. All of these are stabs in the dark. I have also seen an actual black screen caused by Comodo, but it was able to recover without a restart, and I am also aware Nvidia drivers can cause this.

The following are the crash logs for each app:

Hoping someone can impart words of wisdom. The annoying thing is this happens 'now and then' - meaning you can go a week on a new 'attempt' after adjusting something, think the issue is gone, it then happens and you've wasted another week trying to fix it. Can take months to resolve because of this. So could use some useful guidance!

Cheers.

Start menu, Cortana and Notification dont function

try kill Cortana then restart Windows Explorer(explorer.exe) and Desktop Windows Manager(dwm.exe)

 

Desktop Window Manager Memory Leak

This problem appeared after installing Win10 anniversary update. "dwm.exe" used ~1.8GB of memory. This might be a memory leak or something, that's why it eats a lot of Memory.

And it seems that the only way to solve this problem is by simply rebooting, or by killing explorer.exe, launching explorer.exe again, and killing dwm.exe after that.

Please fix this ASAP, because some users might not be aware of this leak that may be causing a lot of slowdowns.

(Memory leak confirmed on 2 Windows 10 devices, Version 1607 build 14393.51)

And yes, I have performed a virus scan.

Thank you.

 

DannyG13, please post your problem in the General Support | Windows 10 Forums

This forum is for Blue Screen (BSOD) problems only as the attention box at the top of the forum says:



Please do not post anything other than Windows 10 Blue Screen Of Death problems in this section.

If you are getting a BSOD then follow the first part of the attention box instructions:

Read the instructions here: Blue Screen of Death (BSOD) Posting Instructions

 

I would recommend making that last line in the instruction box bold. I simply didn't see it. Thank you for the advice, reposted now.

 

DannyG13, I'll mention that to the boss *Smile thanks.
