- Verify all internal power connections (motherboard, CPU, GPU, drives) are firm and correctly seated.
- Ensure the power switch on the back of the power supply (if present) is in the 'ON' position.
- Intermittent Power Loss or System Instability:
- This could indicate an overloaded power supply. Review your system's total power requirements and compare them to the power supply's 460W capacity.
- Check for loose internal connections or damaged cables.
- Ensure adequate cooling within the computer case to prevent thermal shutdowns.
- Unusual Noises:
- A loud fan noise might indicate dust buildup. Clean the fan as described in the Maintenance section.
- If unusual electrical noises (e.g., buzzing, crackling) are heard, immediately power off and unplug the system and seek professional assistance. Do not attempt to operate the system.
