A. 1. Close Unused Applications: If you have multiple applications running, they may be consuming system resources. Close any unnecessary applications to free up memory and processing power. 2. Optimize System Performance: On your computer, go to the task manager and check for any processes that are using excessive CPU or memory. End those tasks if they are not essential. 3. Increase Virtual Memory: If your computer is low on RAM, increasing the virtual memory can help improve performance. Go to System Properties, click on 'Advanced system settings', then 'Settings' under Performance, and adjust the virtual memory settings. 4. Regular Maintenance: Perform regular maintenance on your computer, such as disk cleanup and defragmentation, to improve overall performance.

B. 5. Upgrade Hardware: If performance issues persist, consider upgrading your hardware, such as adding more RAM or switching to a solid-state drive (SSD) for faster data access.
