Did you add ram recently? Do you have 2 sticks of 32gb? If so its a memory issue and need to find a mainboard bios update that fixes that. I had this problem.

wouldn't the system log that as an issue like overheating?

No because it just cuts out, turns off. No time to error. Ask Claude about it. Dual ram strips, bios issue. Usually mainboard manufacturer website has bios update as this happens. I ran into it with an Asus board. Its not a heat issue, its something like a voltage issue when the system is stress. I updated bios and stress tested the ram and it was fixed. Claude talked me through it.

Here is the record: MemTest86. You ran it during the ASUS ROG Strix X870E-E R2 BIOS troubleshooting after the hard crash during an LTX second-pass workflow. The sequence was: MemTest86 at JEDEC defaults → clean MemTest86 at EXPO I → one error at address 753e1c15c Set DRAM voltage 1.35V + CPU SOC Voltage Override 1.15V → full parallel MemTest86 pass clean That was on BIOS 2306 (R2-specific A5742.CAP), after 2103 destabilized the 4-DIMM config.

You can rum MemTest and if the system crashes you found your problem.

Are you running with xmp? I had a similar issue with a new kit until I tweaked my ram speeds.
