ROG STRIX B550-f is paired with RADEON RX5600, RYZEN 5 5600X, Seasonic Focus Plus 850 PLAT, GSKILL RIPJAWS V. Problems appear across various operating systems including Windows 10/11, Debian, Manjaro, and Mint. This issue has remained unresolved despite numerous incorrect assessments. The system occasionally crashes randomly during heavy use or when idle, but no error messages or blue screens occur upon restart. It had previously functioned properly for more than a year before the problem began. Initial assumptions pointed to a failing power supply, which was replaced after an update, yet shutdowns persisted. Subsequent attempts to swap out the motherboard, CPU, and RAM were unsuccessful. Testing with multiple GPUs yielded inconsistent results—sometimes stable for over 24 hours, other times only 30 minutes. Leaving it powered off or unplugged seems to extend its operational time. Despite trying different cables (VGA, DVI, HDMI) and even a new case, the issue continues. I remain uncertain about the root cause, though I’ve ruled out display port cords.
I experimented with line loading calibration, it appeared to assist but the problem remains unresolved.
