Study Notes
PC Preventive Maintenance Overview
- Preventive maintenance is essential to maintain computer performance and longevity.
- Two primary factors for developing maintenance plans are the computer's environment (e.g., dusty construction sites vs. clean office spaces) and usage frequency (e.g., high-traffic networks needing more scrutiny).
Preventive Maintenance - Internal Components
- Regular inspection of crucial internal components is vital for performance:
- CPU heat sink and fan assembly
- RAM modules
- Storage devices (HDD/SSD)
- Adapter cards (graphics, network, etc.)
- Cables and power devices
- Input devices like keyboards and mice
Preventive Maintenance - Environmental Concerns
- Maintains optimal performance by keeping the computer environment clean, contaminant-free, and within manufacturer-recommended temperature and humidity settings.
- Example: Ideal conditions may include 22.0 degrees Celsius, 58% humidity.
Preventive Maintenance - Dust
- External cleaning is necessary to prevent dust accumulation:
- Use a soft cloth or duster for the exterior of the case.
- Limit cleaning products to minimal amounts applied to cloths.
- Dust can obstruct airflow, leading to overheating and potential component failure.
- For internal cleaning, employ compressed air and anti-static vacuum cleaners.
Preventive Maintenance - Software
- Ensure all installed software and security updates are current.
- Develop a software maintenance schedule for:
- Regular updates of security software and drivers.
- Virus definition file updates and system scans.
- Removal of unnecessary programs.
- Regular hard drive error scans and defragmentation.
Troubleshooting Process Steps
- Effective troubleshooting requires an organized and logical approach, developed through experience.
- Always safeguard data before starting troubleshooting procedures.
- The troubleshooting process consists of:
- Identifying the problem
- Establishing a probable cause theory
- Testing the cause theory
- Creating and implementing a resolution plan
- Verifying system functionality and enacting preventive measures if needed
- Documenting all findings and outcomes for future reference
