Occasional black display and failure to start the PC.
The system operates normally under most conditions. Recent events include a brief power interruption where the monitor went dark and failed to respond, followed by intermittent flickering and a brief shutdown. After several attempts to resolve, the issue persists with unresponsive graphics and unstable power delivery. Diagnostic actions such as reassembly, PSU replacement, BIOS reset, and testing in an open environment have not eliminated the problem. The motherboard remains silent during diagnostics, yet components activate without proper signaling. Further troubleshooting should focus on power integrity and potential short circuits, while considering environmental factors like dust or loose connections.
I've tested both setups with the front panel connected and disconnected. I also considered the fans or fan hub, but the problem persists even without them. It seems it's not those components.
It seems the situation was either a hardware failure or an unusual timing issue.
