One of the most common complaints about computers and laptops is slow performance. There are several factors that can contribute to a sluggish system.

How to Troubleshoot:

  • Close unnecessary programs and browser tabs to free up system resources.
  • Perform a disk cleanup to remove temporary files and other unnecessary data.
  • Defragment your hard drive if you're using an older computer with a mechanical hard drive.
  • Check for and remove any malware or viruses using a reputable antivirus software.
  • Update your operating system and drivers to ensure optimal compatibility and performance.

2. Wi-Fi Connectivity Issues

Wi-Fi connectivity issues can be frustrating, especially when working remotely or trying to access important information online.

How to Troubleshoot:

  • Restart your computer and your Wi-Fi router.
  • Move your computer closer to the router, or reposition the router for better signal coverage.
  • Check for and install any available updates for your Wi-Fi adapter's driver.
  • Disable and re-enable the Wi-Fi adapter in your computer's Device Manager.
  • Run the built-in network troubleshooter on your operating system.

3. Unresponsive Applications

Sometimes, applications may freeze or become unresponsive, causing frustration and potential loss of unsaved work.

How to Troubleshoot:

  • Press Ctrl + Alt + Delete and open the Task Manager. Locate the unresponsive application and click "End Task" to force-close it.
  • Restart your computer to resolve any temporary issues.
  • Update the application to the latest version, as this may resolve known bugs or compatibility issues.

A computer that won't boot can cause panic, but there are several troubleshooting steps to take before assuming the worst.

How to Troubleshoot:

  • Check that all cables are securely connected, including the power cable.
  • Remove any external devices, such as USB drives or peripherals, and try booting again.
  • If you're using a laptop, ensure the battery is charged and connected properly.
  • Listen for any unusual noises or error codes during startup, which may indicate a hardware issue.
  • If you're comfortable with it, open the computer case and ensure all components are securely seated.

5. Overheating

Overheating can cause performance issues and even damage your computer's components.

How to Troubleshoot:

  • Ensure your computer's vents are clear of dust and debris.
  • Keep your computer in a cool, well-ventilated area.
