Hard rebooting, at random point in boot process.

[ForcedHero]

I have been working on my PC for the last couple of days ruling things out and am stuck trying to find the exact problem. I was gaming the other day playing Minecraft (low stress game) and my PC hard crashed, no errors or anything, black screens, then the post page as its starting to boot back up. As the PC stands now it rarely boots into the OS and if it ever does it only survives at most a couple of minutes. My current goal is to get HWINFO logs (if I get those I will include there here)

Troubleshooting steps

I have tried separate GPUs, CPU coolers, Operating systems (tried booting to another computers main drive as well as a PBE), removing and changing peripherals, removing internal drives. All fans are spinning as expected. SMART data on all drives is above 96% remaining. I have tried changing the ram slots around and doing slot/dim tests.

 

Specs

CPU: AMD Ryxen 5900x

Cooler: Corsair Hydro Series H150i PRO RGB

RAM: Corsair Vengeance RGB Pro 64GB

Motherboard: ASUS ROG Crosshair VIII Hero

GPU: EVGA 3080 TI FTW3

PSU: Seasonic PRIME 1300W

Reset CMOS first

Then run windows troubleshooting

I have reset CMOS as well. Windows wont boot long enough, I have also tried booting into other drives as well as a usb drive with a PBE to try and restore the drive to a past state (I use veeam to take daily backups of the system) and it behaves the same in both. OS isnt the issue. 


I just got off the phone with ASUS and they are warinty replacing the motherboard.
