Pattern to record: Hardware is healthy yet POST behaviour changes after settings are reset.

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 a stored configuration value is invalid and prevents consistent initialisation.

Preserve recovery options

Unstable overclocking can corrupt data and should not be used during diagnosis. A blanket reset can remove boot, fan, RAID or security settings that must be preserved.

Firmware and hardware checks

1. Return to documented baseline settings and test one hardware group at a time.
2. Save required security and storage details, then test documented defaults.

Recovery and startup checks

If the checks support this cause, clear the affected settings and rebuild only necessary configuration. Verification should cover repeated cold boots, memory load, graphics initialisation, restart and sleep.
