Introduction

Congratulations on assembling your PC! This guide will walk you through proper cable management techniques and the essential steps for a successful first boot. Proper cable management provides several key benefits:

  • Improved Airflow: Properly routed cables reduce obstruction to airflow, potentially lowering temperatures by 3-7°C in some cases.
  • Easier Maintenance: Well-organized cables make component upgrades and cleaning significantly simpler.
  • Reduced Dust Accumulation: Better airflow means less dust buildup over time.
  • Professional Appearance: A clean build looks professional and shows attention to detail.

Cable Management Essentials

Cable Routing Basics

  • Route cables behind the motherboard tray whenever possible
  • Use zip ties or Velcro straps to group cables together
  • Keep power cables away from data cables to reduce interference
  • Leave some slack for components that might need to be removed later

Cable Management Checklist

Power Supply Cables

  • 24-pin ATX power cable
  • 8-pin EPS/CPU power cable
  • PCIe power cables for GPU
  • SATA power cables for drives
  • Molex connections (if needed)

Data Cables

  • SATA data cables
  • Front panel USB headers
  • Audio headers
  • Fan and RGB headers
  • Front panel connectors

First Boot Process

Pre-Boot Checklist

  1. Double-check all power connections
  2. Ensure RAM is properly seated
  3. Verify CPU cooler is properly installed
  4. Confirm storage devices are connected
  5. Check that the GPU is fully seated
  6. Verify all case fans are connected
  7. Ensure front panel connectors are correct

Troubleshooting Common Issues

No Power

  • • Verify the PSU switch is in the "I" (on) position
  • • Check that the power cable is fully seated in the PSU
  • • Ensure the front panel power button is properly connected to the motherboard
  • • Test the power outlet with another device

No Display

  • • Ensure the monitor is powered on and set to the correct input
  • • Verify the GPU is fully seated in the PCIe slot
  • • Check that all power connectors are properly attached to the GPU
  • • Try a different display cable and port (HDMI/DisplayPort)
  • • Test with integrated graphics if available (remove GPU first)

Boot Issues

  • • Ensure the boot drive is properly connected and detected in BIOS
  • • Check the boot order in BIOS settings
  • • Verify the bootable USB is properly created (try recreating it)
  • • Reset BIOS to default settings if experiencing instability

BIOS Setup

After successful POST, you'll need to configure your BIOS settings. Here are the key settings to check:

Essential BIOS Settings

  • Enable XMP/DOCP for RAM
  • Set boot priority
  • Enable TPM (for Windows 11)
  • Configure fan curves
  • Enable Secure Boot

Performance Settings

  • Enable Resizable BAR (if supported)
  • Configure CPU power limits
  • Set PCIe generation
  • Enable virtualization (if needed)
  • Update BIOS if needed

Operating System Installation

i

Have your Windows license key and a USB drive (16GB+) ready before starting the installation process.

  1. Create a bootable USB: Use the official Windows Media Creation Tool or Rufus to create a bootable USB drive.
  2. Boot from USB: Restart your PC and enter the boot menu (usually F12, F11, or DEL) to select your USB drive.
  3. Install Windows: Follow the on-screen instructions, selecting your SSD/HDD as the installation location.
  4. Complete setup: After installation, complete the Windows setup process and connect to your network.

Post-Installation Setup

Essential Software

  • GPU Drivers: Download directly from NVIDIA/AMD/Intel
  • Chipset Drivers: Essential for motherboard functionality
  • Audio Drivers: For proper sound output
  • Network Drivers: Wired and wireless connectivity
  • Peripheral Software: For keyboards, mice, and other devices
  • System Monitoring: HWMonitor, CPU-Z, or HWiNFO

💡 Tip: Download drivers directly from manufacturer websites rather than using third-party tools to ensure you get the latest, most stable versions.

System Security

  • Enable Windows Defender
  • Set up Windows Hello
  • Configure backup solutions
  • Install system monitoring tools
  • Set up a password manager
