Changing Processor in PC – How To


In this article we talk about the processor of changing the processor in a PC.

Tools required for changing processor in PC

There are many tools that can be needed when trying to change the CPU of a computer or laptop. Many require common hand tools others may need some other specific tool to accomplish the task. Below is a list of tools commonly used with instructions on how difficult it is to use them and what type of computer they are used on. A good hardware store should carry most of these items if not all, but electronic supply stores will probably have these tools much cheaper than where you can buy at your local hardware store. These are in no particular order.

  • A couple of screwdrivers with different sizes and shapes will help in loosening screws on the computer case , one flat head and one Philips. Make sure they are not too small or big to fit your computer’s cases openings. Usually a smaller-sized screwdriver is needed for these, but larger size may also work depending on the thickness of the computers case. The biggest issue when trying to pick out a screwdriver set is that you do not want to get too much extra tools included that are large in size because you might have trouble fitting them through your computers holes where it needs screws removed at so usually stick with small sized ones, 5/32 inch should be good enough.
  • An Extension magnet helps you remove screws that are behind your computer tower. If you cannot reach the screw because it is too far in, or there is something blocking it, simply attach this long-handled magnetic extension to help you grab it with ease, and pull it out.
  • A small flashlight will come in handy if you ever find yourself trying to fix something during the night or in a dim room where light is not available otherwise since changing CPU often requires doing the job under the PC. A headlamp also works just as good if not better than any regular flashlight because they strap onto your forehead so your hands are free while working on your project.
  • These tweezers are fairly useful for holding small objects without having to resort to using your fingers. This might be useful in cases where the screws are either too small or too close together, making it difficult for you to hold both with one hand while trying to use the screwdriver on them with the other.
  • A simple flathead screwdriver is very practical because most processors do not require any additional tools when changing them. However, there are exceptions, so this is why it’s recommended that you have at least one more type of screwdriver besides a regular Philips head. For example, LGA2011 processors require a hex driver which is 6-sided and has an Allen bit inside .
  • A common thermal paste comes in many different forms such as: tubes, syringes, and tubs. All serve the same function: to create a more efficient thermal transfer from the surface of the processor to the heat sink. Thermal paste is very cheap and some companies even give it away for free with their products .
  • Processor heatsinks come in many different shapes and sizes, but there are two designs you will commonly see inside of computers: U-shaped or L-shaped. If your processor’s heatsink is not working properly then you might need to get a new one that matches your specific product.
  • A flathead screwdriver set allows access to all types of screws found on most internal devices such as hard drives , fans, DVD/CD drives , motherboards, etcetera. With the right sized screwdriver you can remove the screws that hold your motherboard in place.
  • The next item required for changing a processor is an anti-static wristband. This wristband has an aluminum wire running through it which creates a conductive surface to touch any metal on your case uninterrupted by moisture. When working with computer components it’s best to not wear clothes made of synthetic fibers because they are more prone to creating static electricity than cotton or wool fabrics. Static electricity can damage sensitive equipment so always wear an anti-static wristband when handling electronic devices.

Now that you have all the necessary tools, follow this simple guide to replace your processor.


How to go about changing processor in PC?

Before you decide to upgrade your computer processor, first make sure that the processor is compatible with your current motherboard. Otherwise, this may lead to an additional expense of buying a new motherboard or computer.

Here are some steps to follow when changing the processor:

1) Shut down the computer and unplug all cords from it. Remove the side panel located at its case. Make sure that there is no piece of wire or any metal object near the fan inside so as not to get electrocuted because of static electricity build-up.

2) Locate a specific screw on each corner holding the grille protecting the fan in place – remove these screws using a screwdriver and pull out towards yourself to detach it from its slot using both thumbs.

3) Pull the fan out towards you and get ready to remove the heat sink. Make sure that it is thoroughly cooled before taking it out from its slot or else you will get burned by the hot metallic surface of heat-sink.

4) Detach the metal brackets locking down the current processor using a screwdriver. Remove the old processor and install a new one in its place while making sure that there are matching notches on both sides so as to prevent errors when inserting them into their slots.

5) Once done with replacing, connect all cords back to their respective slots and carefully place back each part onto its original position – grille first followed by side panel then screws do etc.

6) Plug in your computer cord and turn on the power switch. If you see your Windows logo, your computer is running fine.

FAQ section:

Q) Whenever I turn on the switch, the screen on my laptop stays dark – why is this happening?

A) It is possible that your LCD backlight has malfunctioned and would require replacement of the entire LCD module which will be an expensive procedure; unless it’s under warranty, better take it to a technician first for a diagnostic check.

Q) I am trying to install Windows 7 but every time I start my computer, windows XP starts by itself – how can I fix this?

A) Try inserting your windows installation disk first before turning on your computer; usually some old motherboard doesn’t support booting from CD/DVD so make sure your disk is bootable. If it still does not work, try updating your BIOS.

Q) My computer doesn’t turn on when I press the power switch, what’s wrong with it?

A) Check the monitor connection first by plugging an external monitor in your laptop – if you see a picture then it might be a faulty motherboard; otherwise, try taking out the battery and power cord for 5 minutes before turning on again. If nothing happens, better consider replacing your current motherboard hardware.
