How to test for hardware failures in a computer?

Testing for hardware failures in a computer is like checking if all the parts inside your toy robot are working properly.

Hardware is like the body and brain of the computer, it includes things like the processor, memory, hard drive, and power supply. If one part breaks, the whole robot might not work as well.

Imagine your toy robot stops moving. You don’t know if it’s because its legs are broken or its brain is tired. To find out, you can try these things:

• Take the battery out and put it back in, like giving the robot a little rest.
• Try a different power source, maybe a new battery or a different wall plug.
• Listen for strange sounds, like a buzzing motor that should be quiet.

You can also give your robot (or computer) different tasks to see what it does:

• Ask it to run fast, like playing a game.
• Ask it to remember something big, like storing lots of pictures.
• If the robot gets tired or makes mistakes, that might mean one part is not working well.

By checking each part and how they work together, you can find out which hardware needs help!
