A slow computer can be frustrating and impact productivity. Whether caused by excessive background processes, insufficient system resources, or outdated software, addressing the issue can improve performance significantly. This guide provides step-by-step solutions to fix slow PC performance effectively.
Common Causes of a Slow Computer
- High CPU or RAM Usage – Too many applications running simultaneously.
- Fragmented or Full Hard Drive – Lack of storage space slows down performance.

- Startup Programs Overload – Too many apps launching at startup.
- Malware or Viruses – Infections consuming system resources.
