ASUS ROG Strix B650 Motherboard
The red Q-LED signifies a failure during the CPU initialization phase of the Power-On Self-Test (POST), typically caused by an outdated BIOS ROM that lacks the necessary AGESA microcode for newer processor steppings. This state can also be triggered by mechanical discontinuity in the LGA 1718 socket, where uneven mounting pressure or microscopic pin deformation prevents the electrical handshake between the CPU and the chipset. Resolving this requires either a firmware update via the BIOS Flashback feature or a motherboard replacement if socket damage is present.
