The system halted unexpectedly during startup.
The system halted unexpectedly during startup.
A few weeks back, the alarm on my NAS kept ringing nonstop, yet I noticed no faults in the logs or temperature alerts. No recent hardware modifications were made. After a reboot, the issue persisted, leaving me with a black screen and no startup sounds. Once, I managed to enter the BIOS using the standard beep, but that didn’t resolve it. The motherboard was returned via RMA, and they updated the BIOS; it arrived this morning. The first boot worked, so I enabled virtualization and rebooted, but the problem reappeared—intermittent POST/BIOS issues followed, with no further progress. If I ever reach the BIOS, I expect a "BIOS has been reset" notification. I tested the CMOS battery with a multimeter, which showed steady 3.2V. Ran Memtest86 on RAM in another machine without errors. Even when nothing was connected—just CPU and motherboard—the results remained unchanged, not even a no-RAM alert. My system specs: OS Unraid, AMD Ryzen 5 5600G, 3.9 GHz, 6-core processor, Gigabyte B550I AORUS PRO AX Mini ITX AM4, Corsair Vengeance LPX 16 GB DDR4-3000 CL16, two Patriot P300 128 GB M.2-2280 PCIe 3.0 X4 NVMe SSDs, plus Seagate IronWolf NAS HDDs and Corsair SF600 600W PSU.
I’d look for any problems with the power source or the connections. It looks like this might be connected to the PSU.
Despite using the working PSU (RM750x), I'm still experiencing the buzzing problem. I've looked into the BIOS and all temperature and fan warnings are turned off, making it hard to figure out the cause. I ordered a dedicated PSU tester for tomorrow since I wasn't confident in the multimeter results when using a paperclip connection.
