How to Change a Microprocessor

Replacing a microprocessor is an easy but delicate task.

Changing a microprocessor is necessary when making upgrades or repairs. Due to the extremely delicate nature of computer processing chips, you must take great care when handling them. Microprocessors have thousands of tiny gold pins that connect the chip to the motherboard and allow it to handle the millions of processes the computer require to work. Any damage to these pins can render the chip nonfunctional or cause it to perform at a reduced rate.

Things You'll Need

• Nonmagnetized screwdrivers
• Processor
• Heat sink
• Thermal grease

Instructions

Removing the Old Processor

1. Unplug the power supply from the outlet and let the unit sit for a few minutes to dissipate any electrical charges.

2. Slide off the side panel of the computer case by removing any case screws attaching the panel and pressing any release buttons found on the back of the computer. Slide the panel off to expose the interior of the computer.

3. Touch the side of the case to release any static charges in your body and prevent them from harming the circuitry of the computer. Wearing a static wristband is also a beneficial safety precaution.

4. Remove the heat sink from the old processor by unscrewing the fasteners from the motherboard. Some models of heat sinks may require you to remove the motherboard from the case or at least have access to the back of the motherboard from the rear side of the case in order to unscrew the heat sink.

5. Remove the old microprocessor by pressing down on the cage latch and swinging it around the catch. Once the latch is free, the cage should swing open allowing you access to the processor. Remove the old processor very carefully using your fingernails.

Installing the New Processor

1. Place the new processor in the socket and ensure it is placed in the correct direction. There will often be a plastic tab on the processor that matches to a plastic slot on the socket.

2. Close the cage of the processor and latch it shut. This often takes a great amount of force and you might hear a squeaking sound as it seats.

3. Install the new heat sink by following its instructions. Make sure to apply plenty of thermal grease between the heat sink and the processor.

4. Replace the side panel and restore power to begin setting up the computer.

Tips & Warnings

• Be careful when removing the heat sink as there is a multitude of fastener types on the market. Take the time to study the fasteners and ensure you understand how they work. Damaging the motherboard and the heat sink bay is possible if you do not take the proper care.
