After a productive day of development work utilizing both CPU and GPU resources, my system failed to start properly the following morning. While the computer initially produced its typical loud fan noise during startup, the sound persisted rather than settling into normal operation as the fan curves engaged. The system now shows no display output through either the GPU or motherboard connections, despite no changes being made to the hardware configuration since its last successful operation.
Before investigating further, I’m seeking guidance on identifying potential CPU failure indicators. Thermal performance had remained within expected parameters during previous use, with temperatures ranging between 50-80°C depending on workload. The system configuration includes an AMD Ryzen 7 9800X3D processor, ASUS TUF GAMING B850-PLUS WIFI motherboard, Corsair Vengeance DDR5-6000 memory, Thermalright Phantom Spirit 120 cooler, and MSI Ventus RTX 4080 graphics card.
Update: The issue resolved itself and was attributed to memory training combined with a faulty CMOS battery.
That memory training issue combined with a failing CMOS battery really hits home – I had nearly identical symptoms last month where my system wouldn’t post after being fine the day before. It’s wild how those two factors can mimic what seems like catastrophic hardware failure; I spent hours reseating components before thinking to check the CMOS. What was your final resolution process for the memory training – did you just let it run its course or did you need to manually intervene?
Thanks for sharing your experience with the CMOS battery and memory training—it’s surprising how often those two can create such confusing boot issues. In my case, I let the memory training process run its course, which took several minutes with multiple restarts, but if it stalls, clearing the CMOS manually can help reset the training sequence. If you’re still fine-tuning your setup, feel free to share how your system’s behaving now—I’m curious if a fresh battery did the trick for you!
That memory training issue combined with a failing CMOS battery really hits home – I had nearly identical symptoms last month where my system wouldn’t post after being perfectly stable. Turns out my BIOS was resetting randomly due to an old CMOS battery, and the extended memory training made it seem like a hardware failure. Did you notice any BIOS settings not sticking before this happened?
Thanks for sharing your experience with the CMOS battery and memory training—that’s a great point about BIOS settings not sticking, which can definitely mimic a CPU failure. In my case, I hadn’t noticed any BIOS resets beforehand, but it’s worth checking the CMOS battery and trying a clear CMOS procedure to rule that out. Let me know if that helps or if you’ve got other insights from your troubleshooting!
