Choosing the Right Components

Processor (CPU)

When building a desktop PC, the first component we need to consider is the processor (CPU). The CPU is the brain of the computer and has a significant impact on performance. We can choose from various brands, like Intel and AMD.

Consider factors such as core count, clock speed, and power consumption when selecting a CPU. Remember, a powerful CPU also requires a compatible motherboard.

Motherboard

The motherboard is the backbone of the computer, connecting all the components together. When choosing a motherboard, we should ensure it’s compatible with our CPU and other components. Important factors to consider are the chipset, socket type, and RAM compatibility. Also, onboard features like Wi-Fi or Bluetooth are important to consider. Also, consider expansion slots.

Memory (RAM)

Memory (RAM) is essential for running applications and multitasking. We should consider the size (measured in GB) and speed (measured in MHz) when selecting memory. Generally, 16GB will be sufficient for most users in 2024. In addition, we should ensure the RAM is compatible with the motherboard and CPU.

Storage (HDD/SSD)

When it comes to storage, we have two main options: hard disk drives (HDDs) and solid state drives (SSDs). HDDs offer large storage capacities at lower costs. However, they have slower read/write speeds compared to SSDs. SSDs provide faster performance and are more durable.

However, they have a higher cost per gigabyte. We suggest using an SSD for the operating system. We also suggest using an SSD for frequently used applications. We also suggest using an HDD for bulk storage.

Video Card (GPU)

A video card (GPU) renders graphics and displays images on your screen. For gaming or graphics-intensive tasks, a dedicated GPU is necessary for smooth performance. Popular GPU brands include NVIDIA and AMD.

When choosing a GPU, consider factors such as performance, power consumption, and price. Additionally, make sure the power supply can support the GPU’s power requirements.

Power Supply (PSU)

The power supply (PSU) provides the necessary power for all the components in the computer. We should choose a PSU with a wattage that will safely and efficiently power our components. Consider factors such as efficiency rating (80 Plus, Bronze, Silver, Gold, etc.). Also, consider whether the design is modular or non-modular. Consider the cable management options.

Case

The case houses all the components. Choose a case based on design preference, airflow, size, and compatibility with other components. Common form factors include ATX, mATX, and Mini-ITX. When selecting a case, we should ensure it has enough space for all our components. It should also support adequate airflow for cooling.

Cooling System

A proper cooling system is crucial for maintaining optimal temperatures. It also prevents components from overheating. There are two main types of cooling systems: air cooling and liquid cooling.

Air cooling uses fans and heatsinks to dissipate heat. Liquid cooling uses radiators, tubing, and liquid coolant. When choosing a cooling system, consider noise level, cooling performance, and compatibility with our case and components.

Assembling the PC

Preparing the Workspace

Before we start assembling our desktop PC, we need to prepare our workspace. It should be well-lit, spacious, and free of static. Gather all the required tools (we’ll need a Phillips screwdriver and thermal paste). Keep a container handy to store loose screws and other small parts.

Motherboard Installation

Now, let’s begin with the motherboard installation. Lay the PC case on its side and locate the standoff screws. Place the motherboard gently onto these screws, aligning the holes, and secure with the appropriate screws.

Installing the CPU

The next step is installing the CPU. Check the CPU socket on the motherboard, and gently lift the CPU arm. Place the CPU into the socket, taking care to align the notches, and lower the CPU arm to lock it in.

Applying Thermal Paste

Before installing the heatsink, we need to apply thermal paste to ensure good heat transfer between the CPU and heatsink. This can be done by placing a small dot (about the size of a grain of rice) of thermal paste in the center of the CPU. When the heatsink is installed, it will spread the thermal paste evenly.

RAM Installation

Time to install the RAM. Locate the RAM slots on the motherboard, open the retention clips, and insert the RAM sticks by aligning the notches. You should feel a click when the RAM is properly inserted.

Storage Installation

For storage installation, find the appropriate mounting points in your PC case. Screw your hard drive or SSD into place, then connect it to the motherboard using the appropriate cables (SATA for most systems).

Power Supply Installation

Now, we can install the power supply. Secure it to the designated slot in the PC case with screws. Make sure the cooling fan faces outward or downward, depending on the case design.

Connecting the Components

Lastly, connect all the internal components using their respective power and data cables. We’ll also need to connect the case fans, front panel connectors, and any additional peripherals. Make sure to route and manage the cables using zip ties for cleaner and more efficient airflow.

By following these steps, we have successfully assembled our desktop PC. Don’t forget to double-check all connections and test the system before closing the case. Good luck and enjoy your new custom-built computer!

Installing the Operating System

Now that our hardware is assembled, it’s time to install the operating system (OS) on our newly built desktop PC. We will walk you through the essential steps to get it up and running.

Firstly, we need to prepare the installation media on a USB drive or DVD. For operating systems like Windows, we can use the Windows Installation media to create a bootable drive. However, if you prefer using Linux, download the desired distribution and follow their guidelines for creating bootable media, such as Ubuntu.

Once our bootable drive is ready, connect it to one of the USB ports on your desktop PC. Then, power on your computer and press the appropriate key to enter the BIOS setup. This key varies by motherboard, but typically it is the DEL, F2, or F10 key. You can refer to your motherboard’s manual for specific instructions.

Inside the BIOS, we need to change the boot order so that the computer boots from our installation media. Navigate to the “Boot” tab, adjust the boot priority, and make sure your USB drive or DVD is on top of the list. Remember to save your settings and exit the BIOS.

The computer will then restart and begin the OS installation process. Follow the on-screen prompts provided by the installer. This usually involves selecting the language, keyboard layout, and a custom or standard installation. If prompted, choose the SSD or hard drive where your OS will be installed.

During the installation process, you will be asked to create a user account and set a password. Make sure to write down this information, as you’ll need it later to log in.

After the installation is finished, your computer should reboot automatically and load the newly installed OS. Congratulations! You have successfully installed the operating system on your desktop PC.

Remember that you might want to update your drivers to get the best performance out of your newly built PC. Start exploring the new OS, customize it to your liking, and enjoy your handcrafted desktop PC.
