System randomly hard resets

Hello, for a couple of weeks my computer has been instantly restarting (hard resets) seemingly at random intervals. What I mean by "instantly" is that I get no kernel panic, no nice shutdown, nothing. Instead it is similar to if someone would pull the plug out of the computer. The general hardware configuration has been running arch for a while without errors before this started happening. I have noticed that it only seems to reboot when running heavy virtual machines, presumptuously because of the load. This have lead me to believe that it is a power issue, but I have a 750W power supply that should be able to handle the load, I think. I have tried to search for similar problems on the internet, the only thing that I was able to find that seemed similar was this post. Although they end up resorting to Ryzen specific solutions while my system is Intel based. I recently as a last ditch effort tried to reinstall the entire system (I also wanted to change some partitioning) and I am running the latest updates and kernel. Just to be clear the issue started occurring before the reinstall and still occurs. I have tried to look at some logs (journal and dmesg), but I haven't found anything that seems suspicious, tough I am not to experienced in reading those logs. As a final note I do not know which logs could be of interest, so please tell me and I will try to post them. This is my first post, please tell me if I have missed something.

Some information about my system, if it is important:
  OS: Arch Linux x86_64
  Kernel: 5.12.4-zen1-2-zen
  Resolution: 1920x1080, 1920x1080
  CPU: Intel i9-9900K (16) @ 5.000GHz
  GPU: NVIDIA GeForce GTX 1050
  GPU: Intel UHD Graphics 630
  GPU: NVIDIA GeForce RTX 2070 Rev. A
  PSU: 750W
  Memory: 31947MiB

Thanks in advance!

Re: System randomly hard resets

Try lowering your XMP profile. I find (on Ryzen) that if I max out DOCP I get similar. Dropping RAM speed a little and all is stable.

And yes, my RAM all checks out fine with memtest. Just one of those things.

/ is the root of all problems.

Seems like a good solution. Unfortunately I haven't enabled an XMP profile so I don't think it applies to me.
