Could a failing CR2032 Lithium 3V Coin Cell cause the GIGABYTE X670 AORUS ELITE AX to have symptom: No Post?

The CMOS battery maintains the volatile SRAM where BIOS configuration is stored. If a checksum error or invalid overclocking parameter is cached, the initialization logic will hang before video output. Replacing the battery and performing a hard reset clears these parameters, forcing the BIOS to revert to safe-mode defaults and re-initialize the hardware bus.

Could a failing DDR5-5200 MHz JEDEC Memory Kit cause the GIGABYTE X670 AORUS ELITE AX to have symptom: No Post?

The X670 chipset utilizes a complex training sequence to align signal phases between the CPU and memory. Incompatibility between the motherboard's AGESA microcode and the RAM's SPD profile can cause a fatal hang during the 'Memory Training' phase of POST. A JEDEC-standard kit ensures the motherboard can establish a baseline handshake and complete the boot sequence.

Could a failing Gigabyte X670 Aorus Elite AX Motherboard cause the GIGABYTE X670 AORUS ELITE AX to have symptom: No Post?

Total failure of the logic board can occur if the PWM controller or MOSFETs in the multi-phase VRM fail to regulate voltage to the CPU. If the CPU does not receive the Power Good (PWRGD) signal from the board's power management IC, it will never fetch the first instruction from the BIOS SPI flash chip, resulting in a permanent No Post state.
