How to install a CPU

If a CPU needs to be replaced, you will need to remove the old one and install the new one. If your motherboard supports CPU-overclocking, you can also upgrade it.

  1. Keep your CPU where it is. Remember to turn off your computer and unplug it from the power supply.
  2. Make sure you have a CPU socket for the CPU you are about to replace. If you have an AMD CPU, ensure it is compatible with your motherboard. If you have an Intel CPU, ensure it is compatible with your motherboard. If you plan to use a CPU cooler, remove the fan first.
  3. Before replacing your CPU, ensure you have removed all the RAM modules. If you have not removed them, then you should do so now.
  4. Remove the old CPU and install the new one.
  5. After installing the new CPU, make sure that it is seated correctly. Make sure that you have attached the CPU cooler properly.
  6. If your motherboard has a CPU socket for your processor, then use this socket to install the new CPU in place. If you do not have a CPU socket, install the CPU in a position as close to the motherboard as possible.
  7. Make sure that the processor is seated securely in place.
  8. After installing the CPU, attach the CPU cooler to your system.
  9. Reattach all your RAM modules, then turn on your computer to see if it boots up correctly.

Final words :

If your computer is not booting up correctly, you must replace your motherboard. If it is a reasonably inexpensive motherboard, then this may be something you can do yourself. Remember that you will need to replace the motherboard if its capacitors have failed or if it has been a long time since you upgraded your computer. If you are not confident about upgrading your computer yourself, then take it to a repair shop for repairs.
