How To Build Your Own Computer

If you have ever thought about building your own computer in 2017 you have come to the right place. I will give you step by step instructions on how to build your own computer. First, you need to ascertain the budget you plan to work with

  1. $300-$500 Low end computer
  2. $600 - 1000 mid range computer
  3. $1000 and over - Magic in Your Hands

Your budget will ultimately determine the specification of your computer you plan to build. I will give you instructions on how to build a mid range system with good specifications. So what are the components you will need to build a computer system:

Computer Chassis /  Computer Case
This is the skin of the computer, it is what houses all internal components. The case normally comes equipped with a power supply unit.The power supply unit is what provides power to all computer components.
Computer Case

The motherboard is the main circuit board in the computer, it provides connectivity and integration of devices. When purchasing a mother board, you must ensure that the board is compatible with the type of processor you have in mind to fit on that board. Most motherboards come integrated with video, sound and USB controllers built onto the board. If you plan to do heavy gaming or high end graphics design, the best option is to purchase a good graphics card. A good graphics card will give you better rendering and faster throughput as it has its own memory and processor built on to the card.


Hard Drive
The hard disk is where you permanently store your data.  Storage is relatively cheap today and you can get good price for Terabyte size drives. So for start, you will need a 1 terabyte drive. Ensure that the drive you purchase is compatible with the main-board connection type. So if you buy a SAS hard disk, ensure your motherboard has a SAS connection port. If you buy a SATA hard disk, ensure that your board has a SATA connection port.

  • SAS - Serial Attached SCSI
  • SATA - Serial Advanced Technology Attachment

What would a computer be without memory to hold programs when the computer is booted and in use? You will need a good size memory to start off with. I would recommend at least 16 Gigs of RAM (Random Access Memory)  When buying computer memory, It is important to ensure that the memory is compatible with your motherboard because not all computer memory are the same.
Computer Memory

Central Processing Unit (CPU)
The CPU is the brains of the computer systems and does all the calculations and processing involved in the algorithm of applications. It is normally a square about 1 1/2 inches. It is seated on the motherboard and under the heat sink. The processor  is a mini city of circuits. The more voltage you pump into it, the warmer it gets, because electrons are going through the circuits insanely fast, it heats up quickly and needs to cool off. Hence a heat sink and fan. The heat sink is a heat conductor and pulls the heat from the CPU and the flan blows off that heat.


Optical Disk
You may need an Optical drive (DVD Drive) to install your operating system from. The drive may also come in handy if you decide on burning software.

Display Unit
Get a good computer monitor, after all you cant plug your eyes into the graphics port to see whats going on as your omputer boots.

Yep, you will need this input device to give the computer commands

Extremely handy input device that no one in today's modern computer era can do without.

Time To Assemble Your Computer 
You will need the following items: 
  • A work desk
  • Screwdriver
  • Anti-static mat to discharge static electricity
  • Power Outlet
  1. Remove the motherboard from the box and place on the anti-static bag. 
  2. Remove the CPU from the box and insert into CPU grid on the motherboard
  3. Remove the heat sink and fan from the box and fasten to the heat-sink holding are directly over the CPU
  4. Remove the side panel from the computer case
  5. Remove the front panel where the DVD drive will fit
  6. Insert mother board
  7. Line up mother board screw holes with screw holes in the computer case
  8. Insert screws which came with the motherboard and gently fasten
  9. Once the motherboard is in place, Insert your memory modules onto slots on motherboard, ensure that they are fastened correctly as loose memory can result in system errors.
  10. Remove the hard drive from the box and attach the data cable
  11. The data cable comes with the motherboard while the power cable is already on your power supply which came with your computer case. 
  12. Insert the hard drive into hard drive 3.5 inch bay inside the computer chassis.
  13. fasten the hard disk with screws it came with.
  14. Insert the DVD Drive into the front panel you took out. Ensure that the DVD drive is properly lined up and fasten with screws.
  15. Attach power connectors from the power supply unit to the motherboard, attach power supply connectors to hard drive and DVD drive
  16. Ensure all data connectors are on the dvd drive, hard drive and that they are directly connected to the appropriate slots on the motherboard
  17. The computer case will come with connectors for the front panel. This includes, power button, reset button, hard drive lead light and power lead light. Look for the correct pins on the motherboard and attach them. You will see pins next together with some labling like, "PWR, RST, HD, etc. 
  18. Attach any USB pins to the appropriate USB connectors. This is normally for fron USB connectivity.
  19. Close the computer case
  20. Attach your peripheral devices, Monitor, Keyboard and Mouse
  21. Plug in your monitor to the Power socket
  22. Plug in your Computer to the Power Socket
  23. Ensure that you have your operating system CD ready to do your install.
  24. If all goes well, you are good to go. If not, fine tune the steps and see where you missed out.
You computer should turn on and tell you missing operating system. Insert your windows or Linux CD and click the reset button on the computer case. You computer will restart and begin to read from your DVD drive. If the dvd you inserted is bootable, it will begin the installation process.
