hey Sean,
I threw a few hundred bucks at it, without any proper results but a decent story.
pc went trough some ridiculous testing at one of the highly respected dutch computer stores, every piece of hardware was tested, the software was checked, more stress tests, and quite a few diagnose-focused programs where thrown at it.
Nothing was wrong with the hardware, the cpu, gpu, mobo, psu, hdd’s, ssd’s, m.2.'s all are working fine.
The temperatures never exceeded 42 degrees Celsius on any of the hardware, no faulty wiring, no strange voltage spikes, nothing.
Driver-wise, everything was in order, nothing was interfering, no faulty drivers, no virusses, no trojans, no software running on the background that could result in the crashes.
Literally the ONLY culprit was ue4. (and any ue4 game)
After discussing it with the tech guys the only reasoning they could find was that it might be due to a certain combination of gpu/mobo/win10/whatever drivers resulting in ue4 triggering something that makes either the engine or another driver think it needs to disable itself or at least tell other software its disabled crashing ue4 my pc in the process.
The thing is, as I, nor the tech-peeps know which driver/drivers is/are the culprit there isnt much of a definitive answer on what exactly its causing it.
It can go as far as an exact list of drivers installed on the exact combination of hardware that I have. what I do know for certain is that ue4 is the trigger to the crashes, but the black powder might be something else.
So we tested some more.
