5. Procedure for Computer Assembling
Step 1: Open The Case
The First Step In Assembling A Computer Is To
Open The Computer Case.
To Open The Case, First Remove The Screws Of
The Left Side Cover And Slide The Side Cover.
6. Step 2: Install The Power Supply
The Next Step Is To Install A Power Supply.
There Are Usually Four Screws That Attach
The Power Supply To The Case.
7. Step 3: Attach The Components To Motherboard
The Motherboard Has To Be Prepared
Before Its Installation. To Prepare The
Motherboard, You First Need To Install
The CPU, Then The Heat Sink On The
CPU And CPU Fan.
8. CPU
A CPU Socket Uses A Series Of Pins To Connect A CPU’s
Processor To The Pc’s Motherboard. If A CPU Is Connected Via A
CPU Socket.
9. Heat sink and fan assembly
A Heat Sink And Fan (HSF) Is An Active Cooling Solution
Used To Cool Down Integrated Circuits In Computer Systems,
Commonly The Central Processing Unit (CPU).
11. Installation of RAM
To Install The RAM First On The Motherboard
And Then Fix The Motherboard In The Case. To
Install RAM, First Ensure Its Compatibility With
The Motherboard.
12. After Preparing The Motherboard, You Can Install In
The Computer Case.
Step 4: Install motherboard
13. The Hard Drive Is The Device Which Stores All The Data.

Hard Disk Drive.
Connect SATA Data Cable From Hard Disk Drive Socket To The Motherboard
Socket
Step 5: Install internal drives
Hard drive
14. Power Cables Are Used To Distribute Electricity From The Power
Supply To The Motherboard And Other Components. Data Cables
Transmit Data Between The Motherboard And Storage Devices,
Such As Hard Drives.
Step 6: Connect all internal cables
15. The Advanced Technology Extended (ATX) Main Power Connector
Will Have Either 20 Or 24 Pins.
Step 7: Install motherboard power connections
16. Step 8: Connect external cables to the computer

Computer Case.
20. Step 8: Connect external cables to the computer
Connecting Printer, Scanner, Webcam
21. Step 9: Starting the computer
Always Remember That The First Step Is To Push Power Button Of The
CPU Than The Monitor’s. An Operating System Or System Software
Like Window Or Linux Will Start Loading, Now Your Computer Is Ready
To Use.
