PC with 4 screens - Hard locking

[criticalbarny]

The system:

• Windows 10 64bit
• I5-8400 CPU 2.80GHz
• Samsung SSD 256GB (MZ7LN256HAJQ-00000)
• RAM - Samsung 16GB x2
• NVIDIA NVS 810
• 4 Samsung TV - 43NU7122 Smart LED - 4k
• Supermicro bios C7Z370-CG-L (running version 1.01.0040) - This is the latest according to their website (https://www.supermicro.com/support/resources/results.aspx)
• Network card - Intel(R) I219-V
• Power Supply - Supermicro PWS-502-PQ -- 500 Watt

All the drivers are up to date (It was updated with driver booster 6). 

 

The issue: 

This pc should be able to run 8 hours straight at least without any hiccups. For some weird reason it decides to hard lock after 1-2 hours when running multiple things at once. We need to be able to run the Aggregate client in two different screens and two different browsers on two different screens. I have tried to run the pc for one full day without any programs running, and it works fine. Then I ran it for another 24 hours with only the Aggregate client running, worked as well. Then comes google chorme, mozilla, internet explorer, all of them crash it after 1-2 hours, even if they are the only ones running. I reinstalled video card driver, I reinstalled windows with deleting everything, nothing has worked so far. I also ran a stress-test for 4 hours on the system, all normal + didn't crash. I tried to remove the RAM's one by one see if it would run into anyissues with just one of them, nope still crashes. (Does it matter what slot they are in??)

 

This is the situation....

I'm looking for ideas that could lead me to a solution.

Any help is appreciated. 

 

Side note: The PC was built approximately one year ago. It was shipped from Bulgaria to Hungary without internals being protected.

About the lock-up problems: Have you checked the Windows Event Log? Does the system log have any critical or fatal errors logged before or around the time of the freeze? 

Here's a small intro to the Windows Event Log: https://www.howtogeek.com/123646/htg-explains-what-the-windows-event-viewer-is-and-how-you-can-use-it/

 

I don't know if you've tried taking out the video card and use the integrated video card on the motherboard, and then run all the programs that usually lead to the freeze. This is to see whether or not the video card could be the source of the problems, either software- or hardware-wise.

 

Your motherboard should have HDMI, DisplayPort, and DVI ports.

 

About the placement of the memory on the motherboard, I read the manual for your motherboard, which you can find here, and below is a screenshot from page 2-9.

 

 

Hope you'll find a solution! :)

Hey, thank you for the response. 

 

I did check the event log but nothing ever shows up as error or anything around the time it locks up. Last error or log is 1 hours at least apart from the locking.

 

According to the memory table you posted, it's correct so thx for that. 

 

I will see if I can run two things from the integrated graphics, but I don't think the issue is there but who know.

I could have misunderstood parts of your original post, sorry about that. I thought the system locked up completely, not just the individual browsers.

If the OS doesn't lock up, I'd try looking for some sort of error dump that at least Firefox and Chrome should perform when crashing. This could point you in the direction of the source of the issue.

 

Googling these symptoms returns some results about the applications causing the video card to run out of memory. 

Chrome debugging: https://support.google.com/chrome/a/answer/6271282?hl=en 

(NB: Don't start Chrome after it crashing when looking for error logs, as these are overwritten when Chrome is started again.)

 

Does Chrome detect that it has crashed when you open the browser again? Are the browsers all on the same website when they crash? Does it happen while only on the "New tab" window? 

 

I'm really shooting in the dark here, since these kinds of freezes are really disgusting to troubleshoot.

[criticalbarny]

The OS does lock up completely but there isn't a log about it in the event log, thats why I'm mostly confused. None of the browsers are able to maintain stability. 

 

Chrome comes back with "restore" when I turn on the pc again.

Hmm, really weird symptoms. 

Tried turning off hardware acceleration in Chrome/Firefox? I've seen some other forum posts reporting that hardware acc. in web browsers is causing system freezes. In Chrome it seems to be enabled by default, and you can access it in Settings --> Advanced --> System

Oh, wow didn't thought about it, although I have also read about that issue. 

 

I will try that on monday, and will get back to you with the results. I appreciate the help

Have a nice weekend.

No problem, glad to help as much as I can, hope you figure it out. 

Wish you a nice weekend as well!

So, turning off the hardware acceleration didn't work. The PC hard locked after 10 min.....

The situation looks worse than I thought.

RAM - Samsung 16GB x2

What is the exact model of RAM? Could you pull one of the sticks and take a picture of the label(s)?

What happens if you run it with less monitors?

I would run one screen at a time and add them later on.

Put two screens on the igpu, 2 on the GPU.
Increase the igpu vram.
Increase the page file.

I tried adding monitors one by one gives me the same issue, regard less of how many are connected. 

 

As suggested above I ran the pc without the video card, and gave me the same result. Although it managed to run around 14-15 hours with two google chorme screens open than it hard locked. (Screens turned off due to power saving, may have been a different issue but still nothing in the event logs)

How much should I increase the vram and the page file?

How much do you have spare?
Around 3 times + would be the max I would do for the page file. You can go higher if you like.

iGPU Vram is again how much do you have? I have no idea how much memory your programs suck up.

However if you're always sitting with 5GB free then allocate all 5GB to the iGPU (It won't use it all unless needed same with the page file, you're only giving it permission to)

If that works then I would begin to lower the amount given if I need that space. If I don't then I'd leave it as is. Your choice.

That memory module isn't on the QVL for the motherboard. However, (a) I doubt that would be an issue at stock RAM speeds, and (b) it does share similar/same specs as the one (!) 16GB DDR4-2400 stick on the list. I was mainly concerned if there was a mismatch between buffering and/or ECC, which it doesn't look like there is.
 

I assume the modules were in the proper slots per the manual?

 

If you have other RAM around, I would try a pair of 8GB sticks to see if that stabilizes things.

 

Other ideas: is the watchdog timer jumper set on the motherboard?
