Pattern to record: The system fails at the same early stage even with minimum known-good hardware.

Record the boot configuration

Separate a stock configuration from memory profiles, CPU tuning and GPU changes. A boot fault that began after tuning should first be reproduced at supported defaults, without increasing voltage to make POST succeed. One possible explanation is that stored firmware code is incomplete or internally inconsistent.

Preserve recovery options

Unstable overclocking can corrupt data and should not be used during diagnosis. An interrupted or wrong firmware image can leave the board unbootable.

Firmware and hardware checks

1. Return to documented baseline settings and test one hardware group at a time.
2. Use the board's supported recovery check and verify firmware integrity before writing anything.

Recovery and startup checks

If the checks support this cause, recover or reflash the exact signed firmware using stable power. Verification should cover repeated cold boots, memory load, graphics initialisation, restart and sleep.
