Programs crash and system freezes during CPU intensive tasks

Hi,
Recently I noticed my PC started freezing and crashing a lot during CPU intensive tasks. I work in 3D graphics and a lot of the stuff I do relies heavily on calculating and processing stuff using CPU, so it's been really affecting my ability to work.

Whenever I'm generating or calculating something using CPU(specifically when using Agisoft Photoscan and World Machine), the computer will randomly crash programs that are running and I'll just get the "XXX stopped working" message without any details about the crash. Sometimes the whole system just stops working and completely freezes and I have to hard reset it. On one or two occasions I've even encountered BSoD. I have recently went through bunch of painful Creators update issues related to GPU rendering, so I believe it is possible that this is somehow related to the update as well - because that was the only SW change I've done in last few weeks.

My setup is i7 6900K, Asus X99-E WS, Hyperx Savage 64GB 2800mhz with Windows 10 Professional. The CPU tends to get quite hot during these intensive tasks, but I do not believe that temperature would cause this, because yesterday I was monitoring the temps quite closely and it crashed even at 70C. No overclocking or anything like that is involved.

I realize that the problem might be caused by the programs themselves, but I have used them for years on this computer on Win7 and Win10 and not once this happened, so the fact that it suddenly started happening with both of them at the same time and only during CPU calculations kinda makes me think that it's either HW or Windows issue.

EDIT: I just did a CPU stress test and whole system froze after like 2 minutes of the test. Temps were around 75-79C when it happened.

Any help would be greatly appreciated!

Thanks!

I would install hardware monitor so you can see if temperatures are the issue as well as fan RPMs. Just watch the temps when you are doing a task that normal fails. Also, when is the last time your cleaned out your system? Cleaning fans and dust off of heatsinks. Also, I check my the thermal paste ever 3-4 years, and apply new thermal paste to my CPU and heatsink. I would use the hardware monitor first to see if you can narrow down the problem. Let me know what you find.

I actually use HW monitor and Afterburner to monitor the temps and usage. All my fans are maxed out almost all the time - I have four aircooled GPUs, so the case runs pretty hot during long rendering session, especially in the summer. The CPU temps when this happens are nowhere near critical though, usually around 75-85C. I know thats is quite hot, especially considering I have watercooled CPU, but I suspect that it's mainly due to high temperatures in my room during summer. I even tried removing all sides of the case and blowing fresh air inside with two big fans to see if the temps improve, but the temps during CPU intensive tasks were pretty much the same as with closed case.

Every couple of months I try to clean the dust in my case, but it's not a very indepth cleaning. Do you think dust could cause crashing of programs that use a lot of CPU? The thermal paste should be fine, I've had this computer for less than a year, so I don't expect it to be dry already.

Thanks for the help, really appreciate it!

Thanks for the suggestion! I tried to update the bios several times, but no matter what I do, the EZ flash utility in my bios keeps saying that the file isn't a proper bios file.

I tried both FAT32 and exFAT, I tried different USB ports, I tried renaming the bios file. But nothing helped. It always just says that it's not a bios file. I'm not sure what else to try. Some people in other threads I found suggested to call ASUS and order chip with the new bios, but I have my doubts that service like this is available here in Czech Republic and I would like to avoid waiting for several days or even weeks before they'd ship it from somewhere else.
Are there any other special steps to update the BIOS I could've missed?

Is this a new issue, or is it a problem that has gotten incrementally worst. Run a diagnostic on memory. Sometimes that doesn't work. Remove RAM until you can isolate the bad dimm. Start off with the minimum amount you need to do what you want. Process of elimination.

I haven't noticed this issue before. It first happened like two-three weeks ago if I remember correctly. It is possible though, that some crashes/freezes might have happened before that, but I just thought it was a separate random incident. I'll give the memory diagnostics a go and see what happens. Thanks!

After few more attempts I found this thread where OP fixed this issue by adding U31 to the name of the file, because his mobo had USB3.1 or something. So I did a bit more research and found out, that since I have USB3.1 version as well I have to rename it to "X99EU31.CA" instead of "X99EWS.CAP".(even though the bios file seemed to be exactly the same for both - same size, same version, same release date...) After I did that I was finally able to update my bios. Will do bunch of tests tonight to see if it helped or not.
