PC cleaning refers to the process of removing dust, dirt, and debris from the internal and external components of a personal computer. This maintenance helps improve airflow, cooling efficiency, and overall performance. Regular cleaning can prevent overheating and extend the lifespan of hardware components like the CPU and graphics card. In addition to physical cleaning, PC cleaning can also involve software maintenance. This includes removing unnecessary files, uninstalling unused programs, and running antivirus scans to eliminate malware. Keeping the operating system and software updated is also essential for optimal performance and security.
