All your parts are here. You’ve double-checked your list. You’re ready to turn a pile of components into a real, working machine.

Pixel Tip

Some manufacturers offer step-by-step video instructions for installing their components.

If you get stuck, search for your part’s model number and “install” or “assembly” on YouTube or the brand’s website—you might find a video that clears things up instantly.

Build Day

This guide is written for absolute beginners. It offers one clear, beginner-safe path—but it’s not the only way to build a PC.

As you gain experience, you may find other workflows that suit your build or your hardware better.

What You'll Need

Required:

  • #2 Phillips screwdriver (magnetic tip if possible)

  • A clean, flat workspace (table or desk)

  • A little patience and time—don’t rush

Highly Recommended:

  • Good lighting (desk lamp or overhead light)

  • A small dish or tray for screws

  • Internet access nearby (for looking up guides or videos)

Optional but Nice to Have:

  • Anti-static wrist strap (especially if you're nervous)

  • Cable ties or Velcro straps (for a clean finish)

Pixel Tip

Before you start connecting things, take a look at how all your components will fit in the case. If something doesn't fit, you want to know sooner rather than later.

What to Install First

Pixel Tip

Read your manuals. Each component will tell you the best way to install them.

  1. Motherboard

For beginners, begin by placing the motherboard on a hard surface.

Then attach the following components, before installing the motherboard into the case:

  1. CPU

  2. CPU Cooler

Pixel Tip

If your cooler is large, heavy, or awkward (like a tall tower or liquid cooling radiator), you will need to install it after the motherboard is mounted into the case.

Your cooler’s manual will usually tell you what’s best.

  1. RAM

  2. NVMe SSD

Pixel Tip

RAM is the only one that should feel weird installing. It requires a little pressure, and you will hear a pop when it snaps into place.

Now we move to working inside the case.

  1. Mount motherboard into case

  2. PSU

  3. Storage

  4. GPU

  5. Extra Fans/lights

Pre-Boot Check

  1. Plug in your monitor, keyboard, and power cable.

  2. Power it on.

  3. If fans spin and you see a logo or BIOS screen, congrats—you POSTed successfully!

  4. Power it off by holding the power button down for several seconds

If it doesn’t boot:

  1. First, unplug the power and other cables

  2. Reseat the RAM and GPU by removing and then reinserting them

  3. Check power cables

  4. Ensure the PSU switch is in the on position

  5. Make sure the monitor input is correct

  6. Reference your motherboard’s LED or beep codes

Tidy Up & Close It Up

**Never stick your hands into the case when the computer is powered on**

  1. Route any loose cables and secure with ties or straps

  2. Check airflow paths (don’t block fans!)

Boot It Up & Install Your OS

Your PC is assembled. The power is plugged in. You’re ready for the moment of truth: pressing that power button.

Plug in your bootable OS USB

  • Turn on the PC

  • Enter BIOS (usually by pressing DEL, F2, or F12 right after powering on)

  • Set USB as your first boot device

  • Save and exit BIOS

  • Follow the install prompts (choose your language, drive, etc.)

CONGRATS!
You built a PC
