MSI MPG B650 Motherboard
The motherboard's chipset and Voltage Regulator Modules (VRMs) manage the power sequencing required to wake the CPU. A failure in the multi-layer PCB traces or a MOSFET prevents the Power-On Self-Test from completing. Replacing the board ensures the underlying logic gates and power phases are functioning to specification.

DDR5 Memory Kit (2x16GB)
The AM5 platform requires complex memory training during the POST sequence. If the Serial Presence Detect (SPD) chip on the RAM or the memory modules themselves exhibit timing instabilities, the BIOS will halt the boot process. Swapping to a known-compatible kit resolves communication errors between the memory controller and the modules.

CR2032 Lithium Coin Cell
This battery provides the voltage necessary to maintain the volatile CMOS memory which stores BIOS settings. If the voltage drops below a critical threshold, the BIOS may become corrupted or stuck in an infinite loop during initialization. A fresh cell ensures the system firmware can maintain a stable configuration state.
