Device shuts down unexpectedly during startup or operation.
Hello everyone, I’ve already explored some related subjects, but they don’t quite match what I’m facing. That’s why I’m trying to clarify my situation. When starting up my PC, it freezes and shuts down abruptly—no reboot, just a sudden stop. It feels like a kill switch. I’ve noticed strange postcodes after repeating the process a few times, gradually moving closer to Windows. Upon loading the screen, it either boots into the OS or powers down again. Please note: nothing has been modified. What happened? I had an ASUS ROG STRIX X470F with a Ryzen 9 3950X and replaced it with an ASUS TUF X570 Plus for a chipset upgrade. Der8auer reviewed the X570 boards positively in his tests, so I decided to give it a try. At the same time, I swapped my PSU from a Coolermaster 80 Bronze 750W to a Gigabyte Aorus "don’t know" 850W.
The problem began. I thought it might be a bad PSU, so I swapped it again—Corsair HX1000i for better reliability. Booting in Windows, especially during gaming or the first 5-15 minutes, sometimes the PC just stops completely.
The issue continues. I checked online—must be the RAM. The CMK16GX4M2B3000C15 (Corsair Vengeance) model isn’t listed as compatible with the Ryzen 3000 series. I changed RAM just yesterday and still faced issues. I tried DOCP 3000MHz, but it didn’t help. After swapping to Hyper X 3600 CL16 16GB (2x8), the problem persisted. I set it to DOCP 3603 MHz, but it still didn’t work.
Testing under normal conditions and after warming up, I passed stress tests and benchmarks. Performance was stable for up to 48 hours. Cinebench scores were good, and Memtest showed no errors. It’s like eating cereal without milk. When I removed the RAM from DOCP and switched to JEDEC, the machine ran smoothly. Still, it’s unclear if this fixes the core issue.
I’m hoping someone can help me get this working within the first 10-30 minutes. Thank you all for your support. If anyone has encountered the same problem, please let me know—I’d really appreciate any guidance. Boombatz3
Hey there, anyone got a suggestion? I'm almost ready to start another MoBo.
