PC fails to start without utilizing the PSU power control—yellow memory indicator present.
Hello everyone, I've just completed assembling my new PC. However, I'm experiencing some unusual issues. After turning on the power supply unit (PSU), I can boot without any trouble—everything seems normal. Benchmarks, stress tests, and gaming are all functioning properly. But when I attempt to start after shutting down or waking from sleep mode, the yellow DRAM indicators light up, the fans spin, yet the system fails to boot or activate. In this state, the motherboard stops responding (power button inactive, reset button also unresponsive). The Q-code shows a "00" and the power button LED remains off. Removing and reattaching the PSU resolves the problem completely. When everything is working correctly, pressing the reset button or rebooting via Windows doesn't cause any issues, and the PC starts normally.
I also encountered difficulties when removing the AMD cooler (Wraith Prism) before installing a 240mm AIO. The CPU was extracted along with it, causing some pin damage. When I tried to boot with the cooler on, I checked for RAM issues but didn't attempt a shutdown and restart. The bent pins were minor, so I repositioned them. The RAM itself isn't the issue, though the DRAM LED did light up when using two kits (Trident Z Neo 3600 CL16 and Crucial 2133 CL15).
I haven't tested another PSU yet, but this behavior seems consistent. Clearing CMOS didn't help either. This suggests a problem with the CPU or memory modules. Despite having brand-new components, I'm still puzzled. Would it be wise to update the BIOS or swap out the RAM and CPU? My PC specs are: motherboard ASUS ROG Crosshair VIII Impact X570 (BIOS 1001), CPU Ryzen 7 3700X, 32GB TRIDENT Z Neo 3600 at 3600MHz, GPU 1080TI, storage Sabrent 500GB NVMe and Crucial MX500 M2 SATA 500GB, PSU Corsair SF750 (SFX). I've updated the BIOS to the latest version (1302), but the issue persists. What should I do next?
I faced the same issue with a ROG X99 Rampage V. It turned out the problem was a faulty BIOS chip. Updating the BIOS, replacing the 5960x with a 4-core XEON, and swapping RAM didn’t resolve it. I dealt with it for years before seeing a thread suggesting that the ROM used by Asus on this board might be unreliable. I’m not saying it’s the same for you, though. My story is finished—I’d just return the item if a BIOS update didn’t fix the issue. It’s unlikely to be the same chip in my experience.
Even minor issues like damaged pins or a faulty socked component might prevent the device from functioning, possibly due to a grounding pin, memory channel, or a defective board.

I realized I needed to include a "baguette" somewhere. Front panel connectors don’t alter the outcome, so I’ll recheck the CPU pins later. That’s the plan if the BIOS update fails.
I retain dual channel, which means I avoided damaging any of those pins.
