I've been running Unraid since for 15+ years, and finally came to a problem I couldn't solve - hopefully someone here has come across a similar situation. I had a Asus W680 motherboard and Intel 14900K with Kingston ECC ram running swimmingly - until the CPU died. 6 months later, and it's replacement died. I'm just done with Intel for now. I kept the ram, the 9500-16i card, case, almost new high quality PSU, and swapped out the MB/CPU for an ASRock Taichi Light, an AMD 9950X, and the biggest cpu heatsink ever to walk the earth. Installed everything - Memtest again (Even though I know the sticks are good from 24+ hour meatiest on the system they were pulled from). Windows ran overnight no issue, andI updated the BIOS to the latest. Pulled out the config changes from the GO file that I put in there to recognize the quick sync iGPU. Booted up Unraid no issue, everything recognized. Removed virtually all plugins, disabled dockers and VMs. Now the spicy part. EVERY SINGLE TIME I start the array, and a parity check starts, the system completely powers down. Not lucks up, not inaccessible. Just a complete power down. No fans, lights - just OFF. It originally happened within minutes. When I made some bios changes, it now power off after 20 - 90 minutes. I've tried to make some community recommended changes in the BiOS (Power Supply Idle Control to typical, Auto for everything, verified ram speed, no overclocking.) The power off is now delayed, but still inevitable. I've attached diagnostics, but I'm now at a loss. Any thoughts? Thanks! spaceship-earth-diagnostics-20250523-2054.zip
