Question Monitor signal going out ?

[WastelandWailer]

So I’ve had my first build for almost 8 months now and all was good. At the beginning my pc would randomly turn off while gaming but after a while I fixed that issue and had no problem for about 6 months. Fast forward to 2 weeks ago, I updated my nvidia drivers to the then latest version and suddenly my game would lose signal to the monitor but the pc was still on. So I restarted and then I found that a few seconds after logging into windows it would lose signal again. So I booted into safe mode and DDUed to reinstall the latest drivers but nothing helped. I DDU again and pick an older driver, still nothing. I repeated this process probably around 4 or 5 times times, picking a different driver each time.

So eventually I end up getting a new GPU and this fixed the issue…for a single day. Next I order a new monitor and while I’m waiting for it to come in, I try to display to my tv which did work and allowed me to game on it until my new monitor arrived so I was convinced it was a dying monitor.

New monitor arrived 2 days ago and was working fine until today where it just randomly out of the blue did it again and I’m truly at a loss as to what to do. Sometimes I lose signal when I start a game and sometimes it’s a few second after logging into Windows, it’s completely random and my pc will sometimes reset itself about 2 minutes after the monitor loses signal as well. I can still hear my game audio through my headphones whenever I lose the signal. Downgrading sometimes works but only for about a day before the problem returns.

I’ve tried the following:

• Booting into safe mode and using DDU to install different drivers
• Using a different HDMI cord
• Using a display port/cord on my newest monitor
• Swapping HDMI ports on the previous monitor
• Reseating Ram and GPU
• Using a different power cable
• Getting a new monitor
• Getting a new GPU
• Using a different PCIE cord on my GPU
• Upgrading to windows 11 (I was desperate)

I’m actually going insane because at this point I have no idea what could be causing this. I may be new to PC troubleshooting but I’m like 90% convinced this is an NVIDIA drivers issue and not my hardware.

How old is the PSU? Noted 2023 but that could mean a year or so with respect to age. History of heavy use for gaming or video editing?

Look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error code, warning, or even an informational event just before or at the time the monitor/video goes out.

No third party tools or installers.

Manually download drivers directly from the applicable (NVIDIA) manufacturer's website. Verify that the website is indeed the real manufacturer. Just because the manufacturer's name appears in the link that does not mean that the website is the real one.

Another thing you can do:

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all cards, connectors, RAM, jumpers, and case connections are fully and firmly in place.

Use a bright flashlight to check everywhere for signs of damage.

Psu is less than a year old. And I’ve been downloading drivers from their website that’s how I get the older versions , I’ve verified that everything is secure as well, and cleaned it out. I believe it’s purely a driver issue because whenever I DDU it never loses signal on desktop whereas with the driver, it sometimes does depending on which one I get. Some lose signal just while idling and some don’t do it until a game starts.

Error codes, etc...?

Look in Reliability History. End user friendly and the timeline format can reveal patterns.

Event Viewer requires more time and effort to navigate and understand. However it can also capture any number of errors, etc. that cause system problems.

How To - How to use Windows 10 Event Viewer | Tom's Hardware Forum (tomshardware.com)

= = = =

Try using Task Manager and Resource Monitor to observe system performance.

Use both tools but only one at a time.

You will need to leave the tool window open and viewable so you can watch what changes when the monitor signal goes out. Hopefully there will be something noticable (watch the graphs) prior to losing the signal and not being able to see.

Check Task Manager and Task Scheduler: look for any unknown or unexpected processes being launched or triggered. Something may be running in the background or later launched that causes the problem.

Maybe something trying to update, backup, or just "phone home".

Lastly: Update History - any failed or problem updates?

Run DISM and sfc/scannow to find and fix any buggy or corrupted files.

Take your time, be methodical. Watch and read carefully.

Ok I’m looking in event viewer and right before I shut down the pc there’s a kernel PnP warning that says “The driver\Driver\WUFR failed to load the device ROOT\DISPLAY\0000” the Event ID is 219. I do have a critical error but I believe that’s just me resetting the PC, It’s a kernel power event.

There’s also a bunch of errors that are spammed a ton all at the same time whose Event ID is 13 and the source is nvlddmkm. All of them mention a “\Device\Video3”


I already tried the scannow when it first happened 2 weeks ago and it fixed 2 corrupted files but the problem persisted

I’ve also done dism but that didn’t find anything

As I was looking through the event viewer and typing this the pc just reset and gave me the Critical Kernal power error.

Looking at reliability monitor and it’s just a lot of “Windows was not properly shut down” and “Desktop Windows Manager stopped working”.
Also very rarely (2 days out of the 6 listed) there’s one called Hardware error, it’s event name is LiveKernelEvent, code is 117.

Try changing HDMI channel inputs on your display - there may be an issue with either the EDID or HDCP 'handshake'. Is the HDMI cable itself faulty? Try an alternative HDMI cable. Try altering the resolution - the display device may not be capable of supporting the resolution the Source is trying to deliver.

Don’t think it’s a resolution thing, I have been running it at 1920x1080 for almost a year with no problems until the graphics driver update. I’ve checked all the HDMI cords and they work with other things so it’s not that, I also just installed a new PSU so it’s not a power thing either. I can boot into safe mode perfectly fine and it doesn’t lose signal whenever I DDU, so it has to be a driver thing but no matter which one I pick it inevitability goes out.

Any wireless video dispay devices?

= = = =

First a bit of brute force.

Open Powershell and run the following cmdletl:

Get-PNPDevice

Look for any occurences of "Video3". Or "WUFR"

Or any other listed devices that you do not recognize or understand.

To help with the cmdlet:

https://learn.microsoft.com/en-us/p...evice/get-pnpdevice?view=windowsserver2025-ps

I am wondering if DDU somewhere, somehow installed the wrong display driver.

Ok I reseated the cpu and added more paste cause there wasn’t a lot and I can run games now, will update if it happens again. Could it really have been the CPU, cause it’s really weird that it would only lose signal and not shut the whole system down right? I mean it did restart itself a few times after it’d lose signal but it didn’t fully power down when it did happen
