Diagnosing the Problem

The first step in any repair is diagnosing the issue. Listen for unusual noises, observe error messages, and note any recent changes in performance. These clues can help you identify whether the problem is hardware or software-related.

For software issues, try restarting your computer or running a virus scan. If the problem persists, consider rolling back recent updates or restoring your system to a previous point.

Hardware Repairs

Cleaning Your Computer

A common issue that affects computer performance is dust buildup. Regularly cleaning your computer can prevent overheating and improve efficiency. Use a can of compressed air to blow out dust from fans, vents, and other components.

Replacing or Upgrading RAM

If your computer is running slowly, upgrading or replacing the RAM can make a significant difference. First, power off your computer and unplug it. Open the case and locate the RAM slots. Carefully remove the existing RAM sticks and replace them with new ones, ensuring they click securely into place.

Software Troubleshooting

Resolving Software Conflicts

Software conflicts can cause programs to crash or your system to slow down. Check for updates for your operating system and applications. Uninstall any recently added software that might be causing issues.
