For the last few weeks, whenever I leave my system alone (idle) I have, on occasion, come back to both monitors in standby and do not come back on with mouse/keyboard activity. Up until this one this morning, the event viewer has not shown any possible issues, just the standard Kernel Power events due to improper shutdown, etc. Now today I get about 6 errors regarding dwm.exe, so I ran sfc and no integrity violations were discovered. Power management is disabled for turning off the display, and I have double checked that it is still configured that way. Windows is up to date as is the Nvidia drivers. I am not sure what else can be causing this issue.

Hello,

That would be the Desktop Window Manager (filename: DWM.EXE).  Perhaps a conflict with a third-party start menu, user interface tweaker or wallpaper management program?

Thanks for the response, I was aware of what DWM was, the only program that I have that it might be conflicting with is DisplayFusion, which I use for multi monitor support, but I have been using it for sometime without issue.

something like that more often then not points to an issue with the GPU or display drivers from my experience.

 

which GPU do you have? Could try a clean install of the drivers to see if that makes any difference

Hello,

Have you tried uninstalling the third-party DisplayFusion app for testing purposes?  Even though it may not have changed, it is possible that Microsoft Windows or your Nvidia video card's device drivers contained a change that introduced an compatibility with the software.

I agree on this. For example, here is an instance where Intel drivers were causing DWM issues https://www.neowin.net/news/new-intel-3001011191-driver-fixes-stability-issues-in-windows-10-and-11-dwm-and-more/

 

Do you have some spare video cards that you can use or borrow from someone?

Asus ROG Strix 2080, I do a clean install of the drivers each time a new version is released

Not yet, as the problem is so random that it has not happened again.

I do not have a spare GPU, I also really need to RMA this card due to a fan issue, that apparently is common on this specific card, but since I do not have any other GPU, I would be without the system for however long it takes to get the card repaired/replaced.

Well in case you need something to hold on to for a while, you can try the GT 730 2gb gddr5 variant from Asus :)

Just buy a super cheap GPU to enable you to use the PC for basic tasks.

So I have had no problems for 2 weeks, then today it did it again while I was away. I have captured the event viewer errors and put them here: https://pastebin.com/kb7wvJ48

It looks like DWM.exe and the Nvidia driver seem to the responsible files.

    • Windows 11 finally gets redesigned Start menu and more in builds 26200.5641 and 26120.4250

      By George P · Posted

      It's an improvement overall but I'm also of the idea that they should just give users more options and let them have the menu they like instead of just going with one outline and some minor options (though finally getting rid of recommended is great). I know people who don't want pins and would rather it all be just the list/grid of apps. Others just want pins, others want them side by side and not up on top of each other. Have more layout options and let people mix and match, problem solved.
    • Audio setup question - onboard realtek + pioneer receiver (analog)

      By Izlude · Posted

      Hi all, I've got a Pioneer VSX 815-k receiver. Love this thing, however, my cat did his business on top of it and kinda recked it... Only analog works (5.1 surround RCA inputs). Normally I'd use toslink from mobo to digital in on the receiver, but the result is a ton of loud white noise over the music. Analog works just fine, so I'm forced to use the 3.5mm jacks on the rear of the mobo to the RCA inputs on the receiver. The issue I face is that there is no DTS or anything fun.. Originally, I could play all my MP3s or watch YouTube etc, and the subwoofer would be booming as I like because of the mixing from the DAC. Now with the analog, none of that is happening  I'm wondering if there's some kind of software solution for Windows to get the subwoofer to play as it did when I had it hooked up through toslink, but for analog out instead. As of now, only audio files that were encoded specifically to produce sound to the sub, will work, but nothing else. As to which onboard sound solution my mobo has, this from the website's description: 121dB SNR AMP-UP Audio with ALC1220 & High-End ESS SABRE 9018 DAC with WIMA audio capacitors Sound BlasterX 720°, the top-of-the-line audio engine solution for 4K gaming and entertainment  yea it uses that wonky SBx 720 app to change the audio effects n stuff.. but doesn't help with my issue Eventually yea, I wanna buy a new one. They're about $80 on ebay after shipping, but that will have to wait.

      Serious question here. Why is the start menu such a heated topic? I can't remember the last time that I used the start menu for anything at all other than it pops up when I hit the WIN key on my keyboard before I type for the program I want to run and then hit Enter or to restart my machine. I honestly wish it would just go away, and it just be replaced with the PowerToys Run menu. Am I missing something with the Start menu? I see people always talking about installing third party replacements and such, but I just wonder what some are actually using the Start menu for that I might be missing out on. Genuine question. Hopefully not offending anyone as I know everyone has their own way to work and access things in the OS.

    • These are the Apple Watch models that support watchOS 26

      By Aditya Tiwari · Posted

      These are the Apple Watch models that support watchOS 26 by Aditya Tiwari Apple has announced the latest operating system upgrade for its smartwatch lineup, called watchOS 26, not watchOS 12, as many expected a while ago. The Cupertino giant has unified the software experience across its platforms by introducing the "Liquid Glass" software design and renaming all the operating systems to version 26. That said, the next question is which Apple Watch models will support watchOS 26. Apple has shared the official list of devices: Apple Watch Ultra 2 Apple Watch Ultra Apple Watch Series 10 Apple Watch Series 9 Apple Watch Series 8 Apple Watch Series 7 Apple Watch Series 6 Apple Watch SE (2nd Generation) The upcoming Apple Watch update brings several new features to your wrist. Liquid Glass design gives a fresh look to the UI with updated Control Center and translucent buttons within apps. It's new Workout Buddy feature can use an Apple Intelligence-enabled iPhone nearby to provide personalized, spoken motivation during workouts. Building on the Double Tap feature, you can now flick your wrist to perform actions like muting incoming calls, silencing timers, and dismissing notifications when your hands are full. It is available on Apple Watch Ultra 2 and Apple Watch Series 9 (or later). watchOS 26 is currently available for testing through the Apple Developer Program. It will roll out to general users during the fall season, when Apple is expected to refresh the Ultra and SE models. Note that your Apple Watch must be paired with an iPhone 11 (or later) or iPhone SE (2nd generation or later) running iOS 26. While the list of Apple Watch models that support watchOS 26 remains the same, it won't work with iPhone Xs/Xs Max and iPhone Xr, which were previously supported on watchOS 11. You can check out the respective lists of supported devices for iOS 26, iPadOS 26, and macOS 26 Tahoe.
