Unusual and unpredictable startup actions observed.
Hey everyone, so I'm getting a PC for some home lab projects. I'm just starting out and looked around to find affordable options. All the components came in and everything worked fine. Once the PC was up, I installed Ubuntu (I'm comfortable with it since I've used Ubuntu before). After about two weeks of installing software, restarting the machine, and doing everything, it would freeze or not boot at all. It got worse over time and I couldn't get it to start. Now it sometimes just hangs completely or fails to boot. The specs are: OS Ubuntu 22.04.3 LTS, RAM 32GB G.Skill Aegis DDR4-3200, CPU AMD Ryzen 5600G, GPU Samsung 970 Pro, and a 600W PSU. The system runs on a 9-core CPU with a modular design. I've tried clearing the CMOS, reseating cables, checking for bent pins, swapping RAM, and even using G.Skill in another system. It worked there. Maybe I have another idea to try. Thanks for your help, Kuchenpirat!
Your setup has a special mix of parts that previously caused trouble. I attempted Ubuntu 22.04 but gave up due to recurring issues every few months. I traced the problem back to the operating system itself, though it remains unclear. Switching to Ubuntu 20.04 resolved the stability concerns. (If dual booting is relevant, let me know.)
Some Samsung SSDs have shown faster wear. It’s possible your drive is affected, but flashing new firmware via Samsung’s tool can halt degradation. A failing drive might explain your symptoms. I don’t know if the drives you received were new or used. Check your power supply in another machine to confirm it’s functioning properly—PSU issues can cause booting problems.
The DRAM debug light may signal memory trouble, but it could also point elsewhere. A CPU issue sometimes appears on the DRAM light even when the CPU is fine, possibly due to a faulty controller. If possible, test your CPU on another system.
Another approach: disconnect all drives (including SSDs) and attempt a boot. This helps eliminate NVMe or software-related complications.
Have a great day!
You've already gone through the standard fixes, so now it's time to check the CPU and motherboard. Testing the CPU is straightforward on another machine and usually affordable to replace. Sometimes CPUs fail unexpectedly, which aligns with the DRAM troubleshooting signs. Good luck!
