Basic Troubleshooting

Introduction

This will help you solve simple IT problems step by step.

1. Is the Computer Turning On?

Check:

• Is the computer plugged into the wall?
• Is the power button pressed?

What to do:

• Look for a button with a circle and line (⏻). Press it once.
• If nothing happens, check the power cord is firmly plugged in at both ends.

Still not working?

• Try plugging it into a different outlet.
• Make sure the monitor (screen) is also turned on (some have their own power button).

2. Is the Screen Blank?

Check:

• Is the monitor turned on?
• Is the cable connecting the computer to the monitor plugged in tightly?

What to do:

• Look for a small light on the monitor. If it’s off, press the monitor's power button.
• If the light is on but you see nothing, gently check the cable between the monitor and computer.

3. Is the Mouse or Keyboard Not Working?

Check:

• Are the mouse and keyboard plugged in (usually into USB ports)?
• If they are wireless, do they have batteries?

What to do:

• Unplug and replug the devices into different USB ports (rectangular holes).
• Replace or recharge batteries in wireless devices.

4. Is the Computer Frozen (Not Responding)?

Check:

• Is the screen stuck or not changing?
• Are keyboard or mouse clicks doing nothing?

What to do:

• If nothing happens, hold the power button for 5–10 seconds until the computer shuts off.
• Wait a few seconds, then turn it back on.

5. Are You Having Trouble with the Internet?

Check:

• Is the Wi-Fi or internet cable connected?
• Do you see a little globe or Wi-Fi icon with an "X" on it?

What to do:

• If you're using Wi-Fi, try restarting your router (unplug it, wait 10 seconds, plug it back in).
• Make sure the modem and router have power and are showing lights.

Helpful Tips

• Restarting the computer fixes many small problems. Try turning it off and on.
• If you're unsure, write down what you see or take a picture to ask someone for help.
• Don’t worry—you won’t break anything by checking wires or restarting.
