OBS Streaming suddenly causes BSOD crash and reboot after years of no issues.

[Rob_Unit1]

Hello OBS community, I need help troubleshooting why our OBS crashes to a blue screen then reboots when I start streaming.

Here are the log files.

https://obsproject.com/logs/y7JIQBrOdDKIxVqU

The setup:
We are a church that has a dedicated PC just for streaming. It was custom built for this purpose and nothing else. It's a fairly powerful machine. It's been running OBS for streaming for the last 2+ years and almost never has it glitched. Now it should be noted that since it was installed not a single Windows update has been applied to it. It was custom programmed to never get Windows updates.

About 2 months ago it started crashing once it starts streaming.

I just cannot figure out WHY... WHY does it crash.

So I started testing the hardware.
The Windows Diagnostic RAM test came back negative. No errors

I ran an extended test on the SSD drive. It also found no errors.

I also ran a stress test (Prime95) while watching the internal temps of the CPU, GPU and motherboard. All cores were running at near 100% while running Prime95 and never did any component show any signs of overheating or crashing.

After running the stress test for 30 mins, I shut that down and started streaming. The CPU was just barely over it's idle temp of 100 deg F. CPU usage was at 6-7%. Clearly, OBS streaming was not taxing this machine at all.

After 30 mins of streaming it crashed to a BSOD then rebooted.

I then ran BLUESCREENVIEWER, and as with every time before it pointed to NTOSKRNL as the problem. I'm finding that most people consider it very difficult to find the root cause when it lists NTOSKRNL as the problem.

The OBS crash logs show the last crash it has on record as occurring in OCT 2023. It has no record of all the latest Streaming crashes.

Also, the OBS Log Analyzer found nothing Critical. And the Warning section had 3 points.
1) - OBS needed updating
2) - Integrated GPU
3) - Windows 10 is old, no updates.

As to point 1, back when OBS ver 27 came out, we updated to it and immediately found that our Black Magic decklink input card no longer worked. So dropping back down to ver 26 and the card is running again.

Question, has any version of OBS after 27 seen the return of it working with BlackMagic cards again?

I would greatly appreciate any thoughts as to how to fix the OBS streaming crash to BSOD.
Thanks,
Rob

Have you tested removing the BlackMagic declink? did that device get a device driver update that may require a compatible OS update?
Have you tested to make sure the decklink is that the problem?

Have you tested OBS Studio in portable mode with no plugins, filters, effects, etc (and without the declink... use a USB webcam or similar as an alternate if need be)?

As an IT Professional, I get fixing a device config (we did so in Mfg for decades)... but livestreaming means PC with Internet connection, and not applying security updates... that is a complete No-No... and just asking for trouble... some of which involves OS certificate updates tied with streaming provider/CDNs. To me, that is simply more work that dealing with potential Win10 OS update issues (Win11 is another story). And that machine is still on OBS v27... the issues we've had have almost exclusively been streaming host oriented, and not OBS Studio rig (or volunteer 'oopses')

Our House of Worship streaming PC (Win10, i7-10700K) is on its own firewall protected streaming network, and I've got an OS backup (years old at this point ... as we simply let Win10 update (Sunday, ~5 days after Patch Tue release... enough time for major oops to be caught and pulled)... knock on wood... so far, no problems. I am planning for a Win11 (begrudingly... typical M$ every other desktop OS PoS) update this summer, as we just don't have adequate Linux expertise to go that direction (as much as I'd prefer that for better OS audio sub-system, and tie-in with mixer). Of Course, I'll be updating that full system backup in advance, doing plenty of testing. And OBS Studio update to match

Log looks decent but your iGPU driver looks like it hasn't been updated since the PC was new. It's from 2019/2020. Not sure if that's the reason for the crash but more than likely killing your ability to update OBS. Latest driver was released in December.

Lawrence_SoCal, thanks for your response. To the best of my knowledge no one has updated the Decklink drivers. I just checked and all BlackMagic drivers on that machine are 2020 or earlier so no the drivers have not been updated.

Question: Do you know if the latest version of OBS once again works with BlackMagic hardware, the way ver 26 did?

By any chance, would you have any experience with a Ubiquity UDM PRO router? That is the router we are using and I'm seeing some instability in the router and was wondering if... under any circumstances' could an unstable internet connection cause a streaming OBS to crash?

Thanks,
Rob

You're going to need to update Windows too. EOL was 12/14/21.

Not an OBS issue, fix your rig.

I don't know... someone else will have to chime in.. or ask that specific question in own thread with Declink specifically called out in subject (Declink users may overlook this thread)
You can always try OBS Studio (separate instance) in portable mode to test

Router issues (and frame drops) should NOT cause issues in OBS Studio (other than alerting you to dropped frames on livestream).
Now, depending on plugins and sources, filters and effects, and if any of your _Source_ Inputs impacted by the router... shouldn't but less certain (not your case, but if NDI video feed going through the router, and video stream got corrupted... ??) but I'm just thinking aloud/guessing

Same just happened to me after updating OBS after not using it for a few months. It might be coincidence though because I had just installed a razer kiyo pro, added the usb camera as the source, clicked on advanced settings and played around with it in obs without issue. OBS crashed whilst closing, so I installed the synapse and chroma software made some tweaks and then re-opened obs with synapse still open, closed synapse after realising you cant see the camera in obs if synapse is open, decided to uninstall both synapse and chroma software using iobit uninstall, went back into obs, opened the properties for the camera in OBS, clicked the configure video option, then clicked advanced, and I got the blue screen of death and the computer restarted automatically.

Since the computer restart I haven't had any issues.
