I've got this unusual setup I run for my lab server. It features a quirky instability—when you switch to BIOS, the machine just restarts after a few seconds. There are no error messages, no warnings, nothing. All power drops and it boots again. The more you interact, the more erratic it becomes. Letting it sit for a bit or moving some parts helps. It feels really unpredictable. I disabled PCIe4, which briefly improved stability but then it went back to being unreliable. If you pause and don’t touch it for about 30 seconds during startup, it runs smoothly. Once it’s up, it works well. It handles heavy workloads constantly, grinding numbers away without any concern. There was a brief glitch in about two years—possibly a cosmic ray. The specs are: ASRock X570M Pro4, BIOS version 3.40, running at 600W, with a 1GB LP SSD, a Ryzen 9 3900X at 3.8GHz, and multiple NVMe drives including an enterprise SSD and an Optane disk. I haven’t updated the BIOS since it would randomly restart. System Power 9, 600W, MSI GeForce GT 710, 1GB RAM. It’s running on all cores nonstop for days. I’ve only noticed one minor issue in the past couple of years, which might have been a cosmic ray. Configuration-wise, it has a mix of enterprise SSD and an older Optane drive. I don’t think these are the main causes since it still drops without warning. Possible ideas: * The memory isn’t on the QVL list for that board * Maybe the power supply is failing because spinning multiple mechanical drives drains it * Could be a hardware fault—worth checking the board * Perhaps the motherboard itself is faulty and needs replacement. It’s also worth noting I use most of the 128GB RAM, so memory isn’t likely the problem. How would you begin troubleshooting?
