1. Step-by-Step Computer Assembly (Building the PC)

Building a computer is like playing LEGO! You connect parts in correct order:

1. Install Power Supply (PSU) : Screw power supply unit into PC case box.
2. Install CPU on Motherboard : Open CPU socket lever, align gold triangle corner on CPU with socket, place gently, and lock lever.
3. Apply Thermal Paste & Heat Sink Fan : Put small pea-sized dot of thermal paste on CPU center, then lock CPU cooler fan on top.
4. Install RAM Memory : Open side clips on RAM slots, align notch, and press down hard until it clicks!
5. Mount Motherboard into Case : Screw motherboard standoffs inside case box, then fix motherboard on top.
6. Install Storage Drives & Cards : Insert SSD/HDD into drive bays, and plug Graphic Card (GPU) into PCIe x16 slot.
7. Connect All Cables : Plug 24-pin main motherboard power cable, 8-pin CPU power cable, SATA data cables, and front panel power button connectors!

⚠️ Assembly Warning: Never force CPU into socket! If it does not slide in smoothly, check triangle orientation corner. Forcing it will bend tiny CPU pins!

💡 Pro Tip: Apply thermal paste the size of a single green pea in the center of CPU. Don't spread too much, or it will spill onto motherboard circuit!

2. Booting the Computer (BIOS & UEFI Setup)

After finishing PC assembly cable connections, press power button to test boot:

• POST (Power-On Self-Test) : Motherboard BIOS performs hardware health check (beep sound or LED lights check RAM, CPU, GPU status).
• BIOS / UEFI Setup :
  • Press DEL or F2 key on keyboard when PC logo screen appears to enter BIOS/UEFI setup utility.
  • Set date/time, check CPU temperature, enable XMP/EXPO RAM speed profile, and change Boot Priority sequence (boot from USB flash drive to install Windows/Linux OS).

💡 Pro Tip: If computer turns on but screen shows no display signal, check if monitor cable is plugged into Graphic Card (GPU) port, NOT motherboard port!

3. Upgrading & Configuring PC Components

When your computer gets slow in future, you don't need to buy brand new PC! You can upgrade hardware components:

• RAM Upgrade : Add another matching RAM stick to enable Dual-Channel mode for 2x faster performance!

• Storage Upgrade : Swap old mechanical HDD drive with fast NVMe M.2 SSD for instant Windows startup boot speed.
• GPU & Power Upgrade : Upgrade graphic card for video editing or gaming (check PSU wattage compatibility!).
