Erratic Mouse or Keyboard Behaviour? Try These Fixes! (2023)

A smooth and responsive mouse and keyboard are essential components of any computing experience. However, there are times when they can behave erratically, causing frustration and hindering productivity. In 2023, with technology constantly evolving, it’s important to be equipped with the knowledge to troubleshoot these issues. This article will provide a comprehensive guide on how to fix erratic mouse or keyboard behavior, ensuring a seamless computing experience.

Wireless Interference

Issue 1: Wireless Interference


1. Check Batteries: If you’re using wireless peripherals, ensure that the batteries are not low. Replace them with fresh ones if needed.

2. Reconnect the Device: Try reconnecting the wireless device to its receiver. Sometimes, a loose connection can cause erratic behavior.

3. Remove Interference Sources: Keep other electronic devices that may cause interference (such as cordless phones or other wireless devices) away from your computer.

Issue 2: Outdated or Incompatible Drivers


1. Update Drivers: Visit the official website of the manufacturer of your mouse and keyboard to download and install the latest drivers. This ensures compatibility with your operating system.

2. Use Default Drivers: If you’re experiencing issues after updating drivers, try using the default drivers provided by the operating system. Sometimes, third-party drivers may cause compatibility issues.

Issue 3: Dirt or Debris


1. Clean the Peripherals: Use a can of compressed air or a small brush to clean any dirt, dust, or debris that may have accumulated around the keys or mouse sensor. This can significantly improve performance.

2. Clean Mousepad or Surface: Ensure that the surface your mouse is resting on is clean and free of dust or crumbs. A clean surface can lead to more accurate tracking.

Issue 4: Software Conflicts


1. Boot in Safe Mode: Restart your computer in Safe Mode. This will load only essential drivers and services, allowing you to determine if a third-party software is causing the issue.

2. Use Task Manager: Open the Task Manager (Ctrl + Shift + Esc) and check for any processes or applications that might be consuming an unusually high amount of system resources. End these tasks if necessary.

Issue 5: Sticky Keys or Modifier Key Stuck


1. Check Sticky Keys Settings: In the Control Panel (Windows) or System Preferences (Mac), ensure that Sticky Keys are disabled. This prevents the computer from registering a keypress multiple times.

2. Inspect Physical Keys: For keyboards, check if any physical keys are stuck or have debris lodged beneath them. Gently clean or unstick them if needed.

Issue 6: External Interference


1. Change USB Ports: If you’re using USB peripherals, try connecting them to different USB ports on your computer. A faulty or overloaded USB port can cause erratic behavior.

2. Use Ferrite Cores: Attach ferrite cores to the USB cables. These devices can help filter out electromagnetic interference that may be affecting your peripherals.

Issue 7: Malware or Virus Infection


1. Run Antivirus Scan: Perform a thorough scan of your computer using reliable antivirus software to detect and remove any malware or viruses that may be causing system instability.

2. Update Security Software: Ensure that your antivirus and anti-malware programs are up-to-date to protect against the latest threats.

Issue 8: Hardware Malfunction


1. Test on Another Computer: If possible, connect your mouse and keyboard to another computer to see if the erratic behavior persists. This will help determine if the issue lies with the peripherals or the computer itself.

2. Contact Manufacturer Support: If your mouse or keyboard is still under warranty and the issue appears to be hardware-related, contact the manufacturer’s support for further assistance.


Erratic mouse or keyboard behavior can be frustrating, but with the right troubleshooting steps, most issues can be resolved. By following the solutions outlined in this guide, you can address common problems and enjoy a smooth computing experience in 2023. Remember to be patient and methodical in your approach, and don’t hesitate to seek professional help if needed. A well-functioning mouse and keyboard are essential tools for productivity, and with these fixes, you can ensure they perform optimally.
