Crashes my entire computer (Win11, 7950X3D, RTX 4090)

[dan_6598]

Since a while I have problems with Lightroom CC crashing my whole computer, resetting it.

My computer in brief: Ryzen 7950X3D, Asus ROG Strix B650E-F, 64 GB DDR5-6000, MSI RTX 4090, 1000 W Phanteks AMP, Windows 11. All drivers including chipset drivers updated.

Symptoms: It happens semi-randomly, but seems tied to when Lightroom CC does some heavy lifting, such as generating previews, exporting images or just scrolling between images in library or development modules. The screen goes blank and the computer reboots.

I am quite certain this is not heat or current related. The reasons for that:
* It only happens when using Lightroom, not when playing demanding games such as MSFS2020.
* It has happened while I was monitoring temps. CPU temp was not high and the GPU barely active.
* Once I was looking at the task manager while it happened. It was not entirely sudden. I was generating previews when I saw CPU use drop sharply. Then, after a few seconds, the reboot came. Had it been a temp/current issue it should have happened while the load was high, but the load dropped and THEN everything crashed.

Other troubleshooting done:
I've run memtest86 to detect defects in my RAM, but none were found. I've also downclocked the memory to 4800 MHz but that didn't help.

I'm now going to try turning GPU acceleration off entirely, but that would be a shame.

So - is this a familiar problem? Any suggestions?

I'll post an excerpt of Lightroom's System information in the next post, I think I saw a recommendation to do that.

Since a while I have problems with Lightroom CC Classic crashing my whole computer, resetting it.

Symptoms: It happens semi-randomly, but seems tied to when Lightroom CC Classic does some heavy lifting, such as generating previews, exporting images or just scrolling between images in library or development modules. The screen goes blank and the computer reboots.

The cause of entire computer crashing is always either a bad driver (most likely your GPU driver is bad/corrupted/out-of-date, but it could be other drivers), or a hardware malfunction somewhere. If it happens when LrC is doing heavy lifting, this seems to be hardware related, and the first thing I would check is the cooling system — check if it is not working properly causing your computer to overheat.

[dan_6598]

Generally I would agree, but if you read my post I argue specifically for this not being likely in this case.

Yes you did, and I still feel I will state my general belief that it is either hardware or drivers (for the benefit of anyone else with the same problem who is reading along).

Did you check for bad drivers?

[dan_6598]

Ok, maybe I came off a bit irritated-sound in that reply. My apologies for that.

And I guess theoretically the drivers could be corrupted but it has persisted over several driver updates of nearly everything in the computer. Maybe if I uninstalled the graphics drivers before updating them again?

Leaking cooling is unlikely, then I would have problems also when not using Lightroom.

By @dan_6598

I only had problems with leaking cooling when I was using Lightroom Classic, because it stressed the system more than any other software I had.

[dj_paige]

I also had it happen to me with liquid cooling system that it wasn't the overheating that caused the problem but liquid leaking out of the system causing short circuits in the electronics. So monitoring the temperature isn't enough to say that the cooling system is working properly.

downclocked the memory to 4800 MHz

Does this mean that you were overclocking the computer?

• LrC can have issues with overclocking, typically with overclocking the GPU, not so much the RAM or CPU, and typically if using a third party application to do that as opposed to the controls provided by the GPU manufacturer, or settings in BIOS. MSI Afterburner comes to mind. These are often items initiated by "Gamers"
• By the way, LrC is a huge resource hog, it can be worse than some games.
• Recently a Windows user found that reverting Hardware-Accelerated-GPU-Scheduling (HAGS) back to Off (the member was having memory leaks), I suspect this is a rare odd event (I had never known of that one before)

[dan_6598]

Not really overclocking, no. I use the AMD EXPO setting to allow the memory to run at its desgined 6000 MHz. Other than that, nothing. And reverting to the very conservative 4800 MHz setting didn't prevent crashing.

Monitoring the temperature is a good diagnostic for overheating. But what you describe is not entirely dispositive:

- LR utilizes the CPU, GPU, and memory (thus generating more heat) much more than many/most games. Many reports here over the years from people who observed that LR causes crashes due to overheating while other apps, including games, didn't.

- When you see CPU utilization drop followed by a reboot, that can occur when the CPU's firmware and/or the operating system notice a spike in temperature, at which point they'll drop the processor clock speed dramatically and sometimes throttle the thread scheduler.  If that's too-little too-late, then the firmware will abruptly shut down.

So use a monitoring utility that shows CPU clock speed as well as both CPU and GPU temperature.

[dan_6598]

I guess I could use Hwinfo64 while trying to provoke something, and having it log data as it goes.

[dan_6598]

Update: I've now been using LR for some hours with GPU turned off. So far no crashes, which is both good (no crashes, good) and bad (bummer if I can't use it). But it's not conclusive yet. Well, things seldom are entirely conclusive with intermittent crashes.

When I go to bed I'll see if I can leave it generating 1:1 previews for a 5000+ images gallery I'm currently working with.

[dan_6598]

New update: I downloaded HWinfo64 and started a log. I then started the big preview generation, whereupon the computer immediately rebooted. As in... immediately. Well, I guess that rules out the GPU as a culprit which is always someting.

When I check the event logger in Windows I find no entry at all at the time of the crash, which I guess points in the direction of power being the problem.

I'm not used to reading the Hwinfo log but I suspect it didn't have the time to record anything. It only logs every other second and that was probably too slow. I may have missed something but I don't see anything noteworthy in it. I'll attach it here just for the sake of it.

And now I have to go to bed. May try again tomorrow. Thanks for the replies so far.

[GoldingD]

So, have you opened up that computer and inspected every power connection, and checked the GPU (as in properly in slot and properly wired ) and cleared out any dust, and generally looked for any component breakage/leakage.

[dan_6598]

I have now. Remarkably tidy in there! Very little visible dust visible even after blowing at suspicious nooks, and this after a year of use - the dust filters appear to be better than in my former case. Now I have an NZXT H7 Flow. No sign whatsoever of leakage or loose components or cables.

[GoldingD]

As for the event viewer, despite nothing showing up at crash time, how about any critical events since computer was started?

[dan_6598]

Yes. I didn't mention that in the post above, and it's in Swedish, but there was a Critical entry upon reboot stating that the computer was restarted without having been shut down properly, which usually happens at system crashes or power outage.

Pretty much expected.
