i9 14900k randomly crashing

[Trooper1]

I recently built this Computer, and it was crashing fairly often until I updated the bios and utilized the enforce intel power option, it's crashing less often now, but still randomly crashing once every 1-2 days. I was hoping someone might be able to help me track down the issue or offer bios setting suggestions to gain system stability.

When a crash occurs, there's no blue screen or anything, PC just randomly shuts itself off, and then a few seconds later comes right back on, and lasts for another day or two before doing the same. I could be gaming or just sitting on the desktop.
Since it's doing it less often with latest motherboard bios installed and intel limits enforced, It seems to me like it may be CPU or Bios setting related.

I'm concerned that during the time the motherboard CPU power limits were set quite high in the bios by default, it may have inadvertently caused minor damage to the CPU?

I have run an Intel Processor Diagnostic Tool CPU test and it passed.
I ran a Windows Memory Diagnostic test, which came back good.
I also double-checked that PL1 and PL2 were set correctly after enforcing Intel power limits.
Most recently, I have tried setting the SVID to "Worst Case Scenario" in bios.

My PC Setup:
CPU: intel i9 14900k cpu with XMP disabled and intel power limits enforced
CPU Cooling: Corsair AIO Liquid Cooling
Motherboard: ASUS TUF GAMING Z790-PLUS WIFI
Corsair CMH64GX5M2B6400C32 32gb x2 memory sticks
NVIDIA GeForce RTX 3080 Graphics card
PSU: Corsair HX1200i 1000+Watt Platinum Cert
OS storage: Samsung 990 PRO SSD 2TB M.2 NVMe (+Various other secondary storage drives)
Case and cooling: Lian-Li 4x 120mm case fans, 3 front 1 back, (2 top attached to AIO liquid cpu cooler)

I have attached Intel SSU, Event Viewer Logs, and below is a link to my memory.dmp file (although that seems to be corrupted when I tried to look at it myself). Event logs only seemed to tell me kernel power lost, with no reason given.

Any help is appreciated!
Thanks

It crashed once more this morning, this time sitting on the desktop with not much open. (Current SVID setting was Worst case scenario, I have now bumped that down to Intel's fail-safe SVID option).

I happened to be looking at the temperatures as the crash happened with HWInfo, all seemed fine with CPU core Temp at 43 C, and CPU Package temp at 45 C, and Core Max temp at 47 C.

I had been gaming prior and noticed that throttling must have engaged briefly, as I did not see a spike in temperatures in the graph; but the Maximum Core and package temperatures had recorded fairly high values. Not sure if that is an error with HWInfo temp sensor recording. Below is a screen grab of that taken just before crash. Graph values from left to right are Current > Minimum > Maximum > Average.

To follow up, I don't think temps are related to my issue, although (of some concern) I am noticing temperature spikes on the CPU Package now during high application usage like helldivers throwing up an error and closing itself. The PC itself did not repeat the issue of crashing during this time and remained stable. Screenshots attached.

Update:
I was just browsing the web today and at around noon after maybe 2-4 hours of PC use the OS grew unresponsive and then fully froze, necessitating a restart. While less dramatic than a full on crash, still just as troublesome.

The pattern I've noticed so far is that after a nightly shutdown, coming back to turn on the PC in the morning it works fine for 2-4 hours and then has an issue forcing a restart; and then works fine for however long until I shut it back down again for the night 8+ hours later.

If someone has to resort to Intel's Failsafe SVID option, and is still not 100% fully stable, would you guys recommend a CPU RMA?

[Trooper1]

Further Update:
PC has fully crashed and restarted again today, does it once every day sometime 2-4 hours after booting up.
Even after setting SVID option to Intel Fail-safe.
Issue is not resolved, Assistance Requested.

Chip has been RMA'd, but the problem persists. PC continues to crash at least once a day. 3 times over 3 days so far with new chip.
Just a random complete cut off like someone threw the power switch, and a couple seconds later it restarts. Fairly hard crash.
It's gotten to the point now that the problem is slowly killing my Hard Disk (Platter) Drives, due to the sudden random system shut offs, I've already had to replace one large very expensive drive.
Any assistance would be appreciated.

Applications that crashed often before the RMA seem to crash less / not at all after the RMA,
But my PC just did a random power off and restart once again so the issue persists.. 4th pc crash in 4 days since RMA.

[Trooper1]

Alright after sending in for RMA the processor, application and system stability seem greatly improved.

I still have the issue of the PC randomly restarting itself 4-6 hours after a user initiated full shutdown or restart; but as long as I don't shut down or restart it again after that, it remains completely stable (so far - up time is around 2 days right now and no crashes during testing any high utilization 3d applications such as Helldivers or other games.)

My "workaround" is to make extensive use of the system sleep / hibernation function, so as to manually restart / shutdown my PC as little as possible. xD

Some research leads me to believe this issue may be related to the corsair rgb software called "iCue". I have closed that app and disabled it from running on start up, with rgb profile saved to hardware mode. I will continue to gather further information and test to see if my issue listed above is resolved when next I have to do a system shutdown or restart.

Still having occasional crashes..
I have implemented intel's recommended bios settings for the 14900k, crashes have lessoned, but still exist in certain games after a while such as counter strike 2. Hard crash and restart.
Loading into Star Wars Battlefront II used to cause a crash, but no longer after the bios changes.
I was getting access violation errors in dump files from CS2, but no longer after the bios changes.
Still hitting 100 C CPU Core and Package temps occasionally, screenshot attached.

[Trooper1]

While running X4: Foundation, CPU Utilization is at around 30%, and Core Thermal Throttling and Package/Ring Thermal Throttling is occurring. With CPU Package Temp spikes up to 98-100 C.

Albeit, this was with a game download and install going in the background.
Even after that finished, throttling is still occurring randomly.

Notably, in my most recent round of bios changes, I changed the SVID from Best case scenario to Typical Scenario. (Could this account for the increase in temperatures?)

Edit:
I've set the SVID back to Best Case Scenario, and my throttling is gone and temps are below 70 in the same game now.
Although oddly, the fps is a bit lower.. with cpu and gpu utilization both around 20-30%. Still playable though, 60 when paused and 40 when unpaused. It's known to be a very processor intensive game.

Now to test if I still get occasional crashes while playing Counter Strike 2.
