What To Do After Building Your PC

The thrill of assembling your very own PC from scratch is undeniable. But what comes next? If you’re wondering what to do after building a PC here’s a comprehensive list of steps to ensure your freshly built computer functions smoothly and is ready for the digital adventures ahead.

1. Inspect and Double-Check

Connections and Seating

  • Ensure all components, such as RAM, graphics cards, and CPU, are seated properly in their respective slots.
  • Check all cable connections, especially power cables, to guarantee they’re snug and connected to the right ports.

Thermal Paste and Cooling

  • Confirm the CPU cooler is attached firmly and that the thermal paste application was adequate.

2. Power On and BIOS

First Boot

  • Switch on the power supply unit (PSU) and boot your computer. You should see the motherboard’s splash screen, indicating a successful POST (Power-On Self-Test).


  • Enter the motherboard’s BIOS/UEFI settings.
  • Update to the latest firmware version if available.
  • Configure the boot order, placing the device with your OS installer (like a USB stick) first.

3. Operating System (OS) Installation

Choosing the OS

  • Windows, Linux, or macOS (for Hackintosh builders)? Choose the one suitable for your needs.
  • Follow the OS-specific instructions for installation, usually provided in the setup process.

Device Drivers

  • After OS installation, install the necessary device drivers. Start with the motherboard/chipset drivers, then GPU, sound, network, etc. Always opt for the latest versions from official websites.

4. Essential Software and Security

Antivirus and Firewall

  • Before browsing the web, ensure you have reliable antivirus software and an active firewall.

Browsers and Plugins

  • Download and install your preferred internet browser, such as Chrome, Firefox, or Edge.


  • Software like CPU-Z, HWMonitor, or Speccy can help you monitor system performance.

5. Performance Checks

Stress Tests

  • Run software like Prime95 or AIDA64 to push your PC to its limits, ensuring stability.

Gaming Benchmarks

  • If your PC is gaming-oriented, run benchmark tests using tools like 3DMark or in-game benchmarks.

6. Personalize and Fine-Tune


  • Customize your desktop background, theme, and icons to match your style.

Performance Settings

  • Adjust power settings for performance or efficiency based on your preference.
  • For gamers, delve into graphics card software for tweaks and optimal settings.

7. Data Migration and Backups

Transfer Data

  • If you’re moving from an old PC, use tools or an external drive to transfer your data.

Regular Backups

  • Set up automatic backups using built-in tools or third-party software. Always have a copy of essential data stored safely.

8. Celebrate and Explore

  • Once you’ve set everything up, it’s time to enjoy your creation! Dive into your favorite games, software, or tasks, and relish the experience.


Building a PC is just the beginning of your journey. Following these post-build steps ensures your computer’s longevity and optimal performance. Remember, the key is in the details. Regular maintenance and updates will keep your custom-built PC running smoothly for years to come.
