To troubleshoot boot issues, first check all cable connections including power, RAM, and GPU. Ensure the RAM is seated correctly in the slots. Clear the CMOS by removing the battery for a few minutes, then reinsert it. If the issue persists, try booting with minimal hardware (CPU, one stick of RAM, and onboard video) to isolate the problem.

Ensure that the SATA cables are securely connected to both the motherboard and the hard drive. Check in the BIOS under 'Advanced' > 'SATA Configuration' to verify that the SATA ports are enabled. If the drive is still not detected, try connecting it to a different SATA port or using a different cable.
To improve cooling, ensure that the case has adequate airflow by installing additional fans if necessary. Consider upgrading the CPU cooler and using thermal paste with better thermal conductivity. Keep the interior of the case free from dust and ensure cables are neatly arranged to avoid obstructing airflow.
