Build a Computer from Scratch

This article will show you how to build a computer from scratch!

Steps

  1. Choose your components. This includes a Motherboard, Graphics/Video Card, Processor, Memory (RAM), Power Supply, Hard Drive, Computer Case, CD Drive, etc.
  2. Make sure all your components will work with each other. When choosing a video card make sure you have the correct connection on your motherboard (ex. pci-e x16 v2, AGP, PCI, PCI-E x16 v1) and calculate the power usage and buy your power supply accordingly. Check the socket on your CPU to see if it is the same as on your motherboard. If it is different, choose a different one (Ex. socket 1366, 775, 478, am2, etc.) and make sure the components will fit.
  3. Read the manuals. You might think that you know what you're doing but check for things you might need to install that you didn't know (Ex. SPDIF cable on n video-cards).
  4. Check if you have all of the components needed to complete your build.
  5. Discharge yourself of any static electricity you may have on your body.You can do this by touching a radiator in your home or a ground wire. If you don't do this step, you might risk damaging your electronic components through a static discharge.
  6. Install your power supply in the casing.
  7. Install the motherboard in your casing. When using an after-market CPU cooler you might need to install some screws onto the motherboard so you might want to do that first to avoid taking everything apart again later. Simply screw it in to your casing through the screw-holes and make sure that you don't over-tighten them.
  8. Install your CPU. Open the socket according to the instructions in your manual and remove the plastic protection cover. Place your CPU in the right orientation (look in the manual), then close the socket. This might take some force because the pins need to make good contact.
  9. Apply thermal paste to the exposed part of your CPU and place your cooler on top. You need to apply only a thin layer of thermal paste. This is to improve the heat transfer to the cooler. Some coolers have thermal paste already applied to them and don't need any other than that.
  10. Screw down the CPU cooler and connect the CPU fan connector.
  11. (Optional) Install your video-card. If your motherboard has an integrated one you may not need to install another one.
  12. Install your memory modules according to their manual.
  13. Insert your hard-drives and optical drives in the racks in the casing.
  14. Connect all of the cables according to their manuals. SATA and/or IDE cables , power-cables, etc.
  15. Now you are ready to start up your computer for the first time. When you start up your computer you may need to set up some settings in the bios menu like your hard drives and your graphics-card. Set everything according to your needs and reboot.
  16. You are now ready to install an OS! whether it is Mac, Windows or Linux ,this is a quite straightforward process and if you do need help you can check out these topics:
