New Information below: 
  I have an X99 Classified that has started to do complete shutdown and restarts without warning.
  i7 6850K
  32GB Corsair RAM
  EVGA 980ti Classified
  Creative Soundblaster Z soundcard
  SAmsung 850 EVO SSD for operating sys + 2TB platter drive
  New thermal paste on CPU and GPU, both looked good when replaced (Not dried out or cooked)
  Im running Bios v2.04
  Windows vers 1903
  Everything is still at stock settings.
  The only change i ever made to the BIOS is to shut off the on board sound.
 
Anybody else have experience with this?
 
I just installed a new EVGA 850 G3 Supernova PSU to eliminate the power supply, and it still does it.
Seems to only happen when online gaming.
 
Every once in a while instead of an unannounced restart, i will get a complete sys lock with no way out except to manually restart.
Sys error code says error 41 Power kernel.
But, thats tough to decipher because, when theres a complete restart, or you have to manually restart it, that is the error you would expect to get, so, thats not really telling me anything.
 
Things i tried:
New Therm past on the CPU
Different CPU
Different GPU
New RAM
 
I installed a new Lamptron fan controller.
one of the thermal temp leads I connected to the surface of the VRM heat sink.
Its reading a regular temp reading of 97f and a temp of 113f while gaming.
Could this be the cause of my random shut downs? It doesnt seem obscenely out of range, but, that still seems hot at idle.
 

monitor CPU temps in the bios. Overheating (possibly not making good contact since you changed that) will cause that or perhaps a low vcore.   Memory instability.   If you can run intel extreme tuning utility, try that and increase vcore until it passes an hour of testing.   
 
also, when you change power supply, use the cables that come with it

Is there a way to run under a load while in the BIOS? 
Overheating is still a possibility. The restarts always happen under a load while gaming, never any where else. The last time thermal paste was used was 18 months ago and has run flawlessly up untill about 2 months ago.  When the restarts began, it was once every two weeks but now twice to three times a day. So, two weeks ago, i reapplied the thermal paste. it seems to have had no effect on the restarts.

well I meant initially, check CPU temp to make sure it's normal in the bios.  But once you run the intel utility, it will tell you temps of each core.   I've had it where I installed a CPU cooling block and I didn't get it set right and I had the reboots.   I had to remove the cooling block and reapply TIM.  
 
Memory instability can cause random freezes too.   Run memtest to rule that out.

Any chance of trying another CPU? A low end Xeon V3 should be dirt cheap nowadays.

Ran a 770 Classified for a while and a 780.
Still had the same problem

You can use hwinfo to log all system temps. I'd also try running on just a single stick of ram.

If the sys does a complete shut down and restart, does HWINFO keep a log? That is the prob ive been running into; once the sys has restarted, there is no more record on event viewer except error 41 power kernel, which only tells me that an unexpected power loss happened (Shut down) and restart takes long enough that EVGA Precision doesnt help to tell me if there was a temp spike that caused it.
 
I did run MeMtest 86 and intel Extreme tuning utility for a couple hours while monitoring the temps and it never crossed 55deg.
 

Yeah, Event ID 41 could be caused by just about anything.

I would make sure to have the latest BIOS (2.09) and drivers installed from the EVGA Download Center..Try setting the RAM to the manufacturers rated frequency/timing/voltage and with a 2N tCMD (Command Rate) or higher, and/or try an X.M.P. profile..Raise the CPU Vcore some, maybe 0.1 volts just for now (1.52V is max spec), you could disable CPU VIN VDroop in the BIOS instead..Increase the VSA Offset Voltage (for CPU integrated memory controller) some, can't say how much, but 1.05v total is typical, 1.2v-1.3v total should be good..Reseat the RAM and clean the "gold fingers" with a pencil eraser and some rubbing alcohol.

Here is the Datasheet (Vol. 1) for your CPU with Electrical Specifications beginning on page 112.

You can set high-temp "Alerts" in the HWiNFO64 settings.
 
If you want the latest version of Win10 (v2004), use the Update Assistant and click "Update now", then "Run".

Just a few things here..Good luck.

113 degrees Fahrenheit is only 45 degrees Celsius - not hot at all, unless the item in question has a very low heat tolerance.
 
If the only things not replaced so far are the motherboard and the drive, that's the next step. The easiest being a fresh windows install (and don't have any other drives plugged in) before buying more hardware. But it looks like the motherboard is the more likely culprit, which I'd look at RMAing after trying a fresh windows install.
 
This is assuming you aren't overclocking anything - if you overclock, the onus is on you to find stable settings.

I did replace the MB also. Still a problem.
I have litterally replaced one piece at a time with the exact same parts or new ones and the problem presists.
I actually have two nearly identical systems here that i have assembled to do testing.
The last thing that is original is the SSD and the platter drive.
After spending 9 hrs running tests this weekend on the drives with no errors, im down to software.
Im down to: Nvidia HD audio software,
                  Corsair ICUE software, or
                  Norton / Windows Defender
 
I did get it to run for 3 hrs last night wit no crashes by turning off Norton auto protect, uninstalling Nvidia HD audio drivers and turning of Corsair ICUE.

Are you using the latest BIOS? 209?  Have you changed all your SATA cables?
  Yes and Yes

Quite odd that you would build an entirely new system yet have the exact issues.
I am assuming you're not cloning an existing install and testing with a brand new clean Windows install?
  No, transfering HDDS between systems
 
Why are you running Norton at all? Windows Defender works well enough if you're not TRYING to get an infection.
  Norton has way more features that i use on eveything else. Otherwise, id just use windows defender.
 
If you're using both Defender and Norton at the same time that definitely could be an issue.
iCue is also buggy. I have both Corsair mouse and keyboard. K95 Plat and M65 Elite. I set up both, save settings to each device then uninstall iCue. I've had no issue with the Nvidia HD driver. 
If the SSD is pretty much the sole link between the two as being an in common item, they have been known to fail too.
 

So, after all that it seems to be a conflict between iCue and Nvidia HD audio drivers.
I uninstalled Nvidia HD audio drivers since i dont use them and it has been stable for 6 hrs when the longest i could go before was about 30 min gaming then crash.
