My workstation specs:
CPUs: 2 * Intel Xeon E5
Mobo: Asus Z10PE-D16WS
GPU: Gigabyte 980 GTX G1 Gaming
128 GB RAM
2 * PCIe Intel 750 SSDs (400 GB & 1.2 TB)
Corsair AX 1500i PSU
2 * ASUS PG279Q ROG Monitors (1440p) with GSync, connected to DP via DP-DP cables.
Sometimes I am getting BSODs with codes 124 and 3B. Most often it happens when PC is in the sleep state, but also it can happen during any process. It can happen up to dozen times per day, but sometimes the problem seem to disappear for a while.
Dumps say that for BSOD code 124 it is PCI Express hardware error, with arguments from the dumps as follows:
Arg1: 0000000000000007, BOOT Error
Arg2: fffffa806e5f08d8, Address of the WHEA_ERROR_RECORD structure.
I am using Matlab and other tools for the data processing. Quite often when I use Matlab extensively, especially plotting something, I get "Low-level graphics error" and a tons of Java heap errors in Matlab, usually accompanied by blackening of the most of a Matlab window (screenshot attached).
Some other minor bugs are also present not only in Matlab.
PC went out of sleep state successfully, then almost always all the open windows move to the main screen and many of them gets resized to a small size. Sometimes the second screen doesn't connect at all and after a few minutes connects back by itself (no cable touching or anything).
Sometimes both screens blink black with no apparent reason. It can be harmless or cause some errors, in Matlab for instance.
There are also some other minor symptoms.
I tried swapping GPUs both to exactly the same ones and to NVidia Quadro - the problems remain almost unchanged. Changing PCI slots arrangement didn't help either. Re-mounting all the components including both CPUs couple times didn't help except once I couldn't start PC up until I carefully re-installed all the memory.
I also tried driver verifier with no luck. Reinstalling the drivers for many things in the system both manually and with driver updater software didn't help either.
I've noticed that with single 1080p monitor connected to HDMI I couldn't reproduce the problems and PC seems to work fine. Also, with just a single monitor connected, the errors seem to happen much less often. I tried swapping cables/monitors (2 identical cables and 2 identical ASUS ROG monitors) but couldn't find any patterns since the errors are sometimes very hard to reproduce and it takes huge amount of time.
Right now after a lot of swapping etc the BSOD problem seems to disappear, at least for the last few days (but it already did it before - disappeared for 3 days and then came back again). But the other things, like screens blinking, second screen disconnecting, Matlab problems etc. are still there, it just doesn't restart anymore.
Any input on what I should do or what the problem could be will be very appreciated. I've been fighting this thing for over a month now.
