Part 2: Internal Computer Parts That Need Attention

Internal parts are more sensitive. Clean them carefully. Always turn off and unplug the computer first.

• Fans
  Fans pull in air. They also pull in dust. Dust makes fans slow and noisy. Use compressed air to clean blades. Clean every two to three months.
• Heat Sink
  The heat sink absorbs heat from the processor. Dust blocks heat release. Clean it with air spray. Do not touch it with wet cloth.
• Power Supply Unit
  The power unit has its own fan. Dust here can cause failure. Do not open it unless trained. Blow air through vents instead.
• Hard Drive Area
  Dust around storage drives traps heat. This affects data safety. Clean the surrounding area gently.
• computer motherboard
  This is the core of the system. It connects all parts. Dust here causes short circuits and heat buildup. Use a soft brush and air blower. Clean slowly and gently. Never use liquid. The computer motherboard should stay clean for stable performance.

Common Mistakes to Avoid While Cleaning

Many computer problems happen because of wrong cleaning methods. Users often rush the process or use unsafe tools. These small mistakes can damage parts and reduce system life. Being aware of what not to do is equally vital as mastering proper cleaning techniques.

• Using Water or Liquid Cleaners Directly
  If liquid reaches the circuits, it can result in short circuits. Use a cloth for cleaning solution, avoiding direct application to the device.
• Cleaning While the Computer Is Plugged In
  Power increases the risk of shock and damage. Always unplug the system before starting.
• Using Rough Cloth or Paper Towels
  These scratch screens and surfaces. A soft microfiber cloth is always safer.
• Ignoring Static Electricity
  Static can damage sensitive components. Touch a metal surface before cleaning internal parts.
• Using Household Brushes
  Normal brushes create static and scratch boards. Use soft anti static brushes only.
• Applying Too Much Force
  Pressing hard can break connectors and pins. Gentle movements are enough for dust removal.
• Opening the Power Supply Unit
  The power unit stores charge even when unplugged. It should not be opened without training.
• Neglecting the computer motherboard
  Skipping this area allows dust to build up over time. Careful cleaning of the computer motherboard improves system stability.

How Often Should You Clean Your Computer

Cleaning frequency depends on usage and environment. A computer in a dusty room needs more care. Homes with pets also see more dust.

External parts should be cleaned weekly. Internal parts can be cleaned every two to three months. If you hear loud fan noise, clean it earlier. Regular checks help you decide the right time.

Signs Your Computer Needs Immediate Cleaning

A computer often gives warning signs before serious damage happens. Loud fan noise is one clear sign. It means dust is blocking airflow. Another sign is sudden overheating. The system may shut down without warning. Slow performance is also common. Apps take longer to open. The screen may freeze often.

Visible dust around vents is another signal. Sticky keys and unresponsive mouse movement also point to dirt buildup. If the computer feels hot even during light tasks, cleaning should not be delayed. Regular checks help catch these signs early and prevent bigger issues.

Room Environment and Its Impact on Computer Dust

The room where a computer sits plays a big role in dust buildup. Rooms with open windows collect more dust. Homes near roads also face this problem. Carpets release tiny fibers that enter the system. Pets add hair and dander to the air.

Placing the computer on the floor increases dust intake. A desk is a better option. Keeping the room clean reduces computer dust too. Simple steps like closing unused windows and cleaning the room weekly help a lot.

Basic Safety Tips Before You Start Cleaning

Cleaning a computer is safe when basic precautions are followed. Ignoring safety steps can damage parts or cause injury. A few simple actions before cleaning protect both the user and the system. These steps should never be skipped.
