Thinking about building your own computer? Have you already got the parts and just don’t know where to start? If so, I am going to show you how to build a computer.
In a recent article I discussed things to keep in mind when you’re going to build a custom computer. There are plenty of websites like PC Part Picker that will generate a parts list. But once you have purchased all of the parts, you’ll have to put them all together.
In his article, I am going to show you how to assemble all of the parts into a working computer. If you don’t have all of the tools or are kind of scared of possibly make a mistake, please contact a local computer shop and have them assemble it for you. If you live in the greater Phoenix, Arizona area, feel free to give us a call.
Tools required to build a computer
- Anti-static wrist strap
- Wire ties
- Snipers (for trimming wire ties)
- Needle nose pliers (optional)
- 3/16″ nut driver (for stand-offs)
- #1 Phillips screw driver
- Thermal compound (may or may not be required)
Building a computer step by step
Cable management is one thing you will need to keep in mind as you are building your computer. Take the time to secure all wires, even if it is temporary.
Don’t be surprised if during your assembly that you have you cut and replaced some wire ties. This is normal when you perform wire management.
And remember to put on the anti-static wrist strap and attach the clip of it to a metal portion of the computer case before you start building your computer.
- Unpack the computer case.
Make sure to do an inventory of all the parts (screws, drive caddies, etc.) that come with it.
- Install the I/O panel in the rear of case.
Be careful installing the I/O panel as the metal edges can easily cut your hand.
- Install the stand-offs for motherboard.
Some cases have stand-offs built-in, others do not. If your case does not have them built in, check the hole pattern on the motherboard or the motherboard manual to ensure you have the stand-offs in the correct locations. Hand tighten them using a 3/16″ nut driver.
- Install the motherboard.
You may have to work it a little bit to get it under any tabs on the I/O panel. Then attach it to the stand-offs using the supplied screws.
- Install the CPU.
Make sure you have the notches in the CPU aligned correctly to the socket on the motherboard. Refer to the motherboard manual for the correct way to secure the CPU in the socket.
- Install the CPU cooler.
If you are using a new cooler, it will have thermal compound already applied. If you are rebuilding an existing computer, you will need to clean any existing thermal compound from the CPU and cooler. Then you will need to apply a new layer of thermal compound. Just spread a thin coat of thermal compound across the complete surface of the CPU. A business card works great.
- Install the memory modules.
The modules will have a notch in them, so they will only go into the slot one way. Check the memory modules against the memory slots on the motherboard for the correct orientation. Also refer to the motherboard manual for the correct installation order.
- Install the case fan(s).
Some cases come with fans already installed, some don’t. If you have to install the can fans, just make sure you have the air flow correct. The air flow should go from the front of the case to the rear of the case. The fans have directional arrows printed on one side of them. Once installed, connect them to the appropriate fan header(s) on the motherboard. Refer to the motherboard manual for the locations.
- Connect the front panel connectors to the motherboard.
Refer to the motherboard manual for the locations of all the pins (power button, power LED, hard drive LED, audio jacks and USB jacks) for the connectors.
- Install the drive(s).
Depending on your case, you may have separate carriages or combination carriages for Solid State Drives (SSD) and Hard Disk Drives (HDD). If you are installing an M2 SSD, refer to the motherboard manual for the correct location for it. If you are also installing CD / DVD drive(s) you may have to remove knock-out metal panel(s) from a 5 1/2″ bay in the front of the case. Be careful twisting it back and forth to break it free, as the metal can be sharp and cut your hand.
- Install the cables for the drive(s).
Refer to the motherboard manual for the correct port to attach the drives to. You will want the primary (boot) drive to be attached to port 1.
- Install any expansion cards (graphics, Wi-Fi, etc.).
Refer to the motherboard manual for the locations of the PCI-e slots. Here is an article we wrote on installing expansion cards.
- Install the power supply.
Depending on the power supply, it may or may not have the power cables already attached. Route the cables thought the case making sure not to cut them on any sharp metal edges.
Now just make sure all of the wire ties are trimmed back and all of the protective film that protects the case is removed. Attach the keyboard, mouse and monitor and go into the BIOS (Basic Input / Output System) to verify and / or change any of the settings. Refer to the motherboard manual on how to do this. Once you are done in the BIOS, you should be ready to install the operating system.
