Before you can repair your computer, you need to identify what’s causing the problem. Some common computer issues include:

  • Blue screen of death
  • Slow performance
  • Unresponsive programs or applications
  • Overheating
  • Hardware failure

Once you’ve identified the issue, you can start working on a solution.

Tools You’ll Need

Before you start fixing your computer, you’ll need a few tools. Here are some essential items you should have on hand:

  • Screwdrivers: You’ll need a set of screwdrivers to open your computer’s case and access the internal components.
  • Compressed air: Over time, dust and debris can build up inside your computer, causing it to overheat. Compressed air can help you clean out the inside of your computer.
  • Thermal paste: If your computer is overheating, you may need to replace the thermal paste on your CPU.
  • Diagnostic software: There are many free diagnostic tools available online that can help you identify problems with your computer.

Common Computer Repairs

Here are some common computer repairs you may need to perform:

  1. Cleaning Your Computer

Over time, dust and debris can build up inside your computer, causing it to overheat and slow down. Cleaning your computer can help improve its performance and prevent overheating.

To clean your computer, start by shutting it down and unplugging it. Open the case and use compressed air to blow out any dust and debris. You can also use a soft, dry brush to gently clean any visible dirt or dust.

  1. Replacing a Hard Drive

If your hard drive is failing, you may need to replace it. To do this, start by backing up all your important files and data. Then, open your computer’s case and locate the hard drive. Remove the cables and screws that are holding the hard drive in place, and then remove the old hard drive. Install the new hard drive and reconnect the cables.

  1. Fixing Overheating

If your computer is overheating, it may be because the thermal paste on your CPU has dried up. To fix this, you’ll need to remove the CPU, clean off the old thermal paste, and apply new thermal paste. This will help conduct heat away from the CPU and prevent overheating.

  1. Updating Drivers and Software

Outdated drivers and software can cause a variety of computer problems, including slow performance and crashes. To fix this, make sure all your drivers and software are up to date. You can do this manually, or you can use a free tool like Driver Booster to update all your drivers automatically.


Repairing your computer can be intimidating, but it’s not as difficult as you might think. With a few essential tools and some basic knowledge, you can fix many common computer problems.
