PC Crashing With no Blue Screen

First off I posted a thread about this on the 5th of May 2018, which now seems to have completely vanished from the forums no matter how I try to find it!

Anyway the current state of the problem I am having is that within a few minutes of having loaded into the operating system the PC crashes with an audible click sound and no blue screen and then restarts itself. Due to my missing thread I no longer have the detailed list of everything I tried, but I tried most of the obvious things such as:
1. Stepping down and then removing CPU overclocking (and removing CMOS battery).
2. Checking temperatures.
3. Different driver versions.
4. Different (known good) graphics card.
5. Different (known good) plug/power wall sockets and extension cables.
6. Re-seating the graphics card.
7. Re-seating the CPU with fresh thermal paste.
8. Booting the PC with almost everything disconnected.
9. I looked at the event logs and all they say are that the shutdown was unexpected.

By the end of all that troubleshooting it was often boot looping before even being able to open the BIOS settings. I stopped using the PC for 6 weeks and then tried a different (known good) PSU the Corsair TX 650W which resolved the issue. Out of interest I then reconnected the originally power supply and everything was still stable.This continued to be the case for over a month. However today I swapped out my GTX 970 for a brand new GTX 1080 and after having connected all my displays and performing a clean install of the latest nvidia drivers I am having the exact same problem as before! When I was previously having the issue I did order a new motherboard to see if that was causing the problem, but when the problem stopped occurring I sent the board back before having used it for testing. If possible I would prefer to avoid trying another motherboard because last time I checked the prices of motherboards that I can use with my CPU are very high.

Sorry I cannot believe I spent ages writing that post and forgot to list the PSUs. :D I have updated the original post to include them. The PSU in the system is a Corsair - RM 850W 80+ Gold Certified Fully-Modular ATX and the one that I used for testing is a Corsair TX 650W.

Ok so yesterday evening after many hours of frustration and exhaustion I retired for the day. First thing today due to the issue occurring with both GPUs I connected the 1080 again and got all 3 monitors setup up with it. Whilst I was disconnecting a PSU from one of my other PCs to use that for testing I left the problematic PC playing music so that I would have a very obvious indication of if it crashes and so far it has been stable for almost 40 minutes. I am so confused, the only thing I can think is that the issue must be somehow connected to how the GPU is seated in the PCI-E slot. Maybe the slot is incredibly fussy about the exact position of the card and so by swapping them around a few times I have managed to get it seated in a working position, but perhaps over time it can work itself ever so slightly loose and that is perhaps what caused me to originally have the issue earlier this year. Every time I have swapped the cards I have done it in the same way, I disconnect the 8 pin power and the outputs remove the 2 case screws holding it in place, take out the card and then do the reverse of all that with the card I am putting it. I will keep an eye on it and see how things go (and try to remember to report back).

Hopefully this means that later today I will be able to VR live stream the newly released Star Trek Bridge Crew TNG DLC that I have been eagerly awaiting!

So after 140 minutes of being totally fine with playing a few games of Star Trek Adversaries (card game) the PC suddenly crashed whilst I was in the game's menu and typing on Discord. Then boot looped a few times before successfully loading again. When it crashes it is basically as if I have pressed the reset button, you here a click and then everything shuts off and the PC restarts. I have been keeping an eye on the temperatures and they have been low the whole time (CPU around 40 and GPU 50-60 celsius). I have installed SpeedFan v4.52, CPUID HWMonitor and Corsair Link and setup the logging for everything I can find.

As far as I can remember whenever I have used temperature measuring software one of the system temperature sensors has always said around 120 celsius, so I have always assumed the sensor is inaccurate, because my PC has been running ok for the majority of 31 months. Could this sensor be causing an emergency shut off because it thinks the temperature is too high even though all the other sensors have vastly lower readings? Also as a side note as soon as I installed Corsair Link it seems to have put my liquid cooling fans at max so they are now making a lot of noise (similar to a standalone house fan)!

Today my PC crashed again and yet again got stuck only turning on for a second or so before clicking and powering down. When this happens it often waits a variable amount of time between automatically trying to start back up (between 2-30s). I swapped the testing PSU in and it had the exact same problem. I also tried the 2 RAM sticks in various configurations with no luck. At this point I am convinced that it is the motherboard that is faulty especially because there are a lot of threads on the MSI forums about very similar issues, all of which have no confirmed solution for the problem! So it looks like I will have to try to RMA it and I have a feeling that 2.5 years is out of the warranty period, so due to the silly prices for the X99 boards these days I will likely have to spend a stupid amount of money to replace it. :(
