Causes of CPU Overconsumption
- Background Processes: PDF and DJVU files, among others, can have background processes that consume CPU resources even when they are idle.
- Outdated Drivers: Outdated drivers, especially for the graphics card, can cause increased CPU usage.
- Malware: Malicious software can consume significant CPU resources, causing your system to slow down.
- Insufficient System Resources: If your system has insufficient resources (RAM, CPU, or disk space), it may struggle to handle multiple opened documents, leading to increased CPU usage.
Potential Solutions
- Update Drivers: Regularly update your drivers, especially the graphics card driver, to ensure optimal performance.
- Use a PDF/DJVU Reader: Instead of opening PDF and DJVU files directly, use a dedicated reader like Adobe Reader or Foxit Reader.
- Disable Background Processes: Some PDF and DJVU readers allow you to disable background processes. Check the settings of your reader to see if this option is available.
- Close Unnecessary Applications: Closing unnecessary applications can free up system resources, reducing CPU usage.
- Increase System Resources: If your system is consistently running low on resources, consider upgrading your RAM or hard drive.
- Run a Malware Scan: Regularly run a malware scan to ensure your system is free from malicious software.
