What is Computer Troubleshooting?

Computer troubleshooting means finding out why a computer is not working properly and fixing it step by step. It helps the computer work correctly again.

We use it for both hardware problems, like a broken keyboard, and software problems, like a program not opening.

Purpose:
The main purpose of troubleshooting is to find the problem and solve it quickly without wasting time or money. It also stops small problems from becoming big ones. Troubleshooting makes your computer faster, safer, and more reliable.

Example:
If a fan stops working, we check the power, motor, and switch one by one to find the problem. In the same way, for a computer, we check the power, connections, programs, or settings step by step until we find what is wrong and fix it.

Why is Computer Troubleshooting Important?

Computer troubleshooting is very important for everyone who uses a computer. It helps find and fix problems step by step. By doing this, we can keep our computer safe, fast, and working well.

Step-by-Step Computer Troubleshooting Process

Troubleshooting a computer may sound difficult, but it is actually very simple if we follow it step by step.

Here is an easy process for beginners:

Identify: First, notice what the problem is. For example, the computer is not turning on, or the screen is blank.

Try: Apply easy fixes one by one. For example, restart the computer, reconnect devices, or update a program.
Confirm: After trying a solution, check if the problem is solved. If not, move to the next step.

Here are some common computer problems with simple fixes:

A computer becomes slow when too many programs are running, storage is full, or the system is not updated.

This usually happens due to a loose cable, a dead battery, or a faulty power supply.
