How to Troubleshoot a Computer


Things You'll Need:

  • Computer Tool Kits
  1. Step 1

    Restart the computer. Many software problems will correct themselves when you do.

  2. Step 2

    Check your cables. Keyboard not working? Make sure it's plugged in. Mouse not responding? Make sure it's plugged in.

  3. Step 3

    Check the electric power. Plug a lamp into the same power outlet that's connected to your computer to make sure the outlet is working.

  4. Step 4

    Make sure the computer and monitor are plugged in.

  5. Step 5

    Disconnect peripheral devices (such as a printer or external Zip disk) and restart the computer.

  6. Step 6

    Listen for unusual sounds. Is the cooling fan running? Is the hard drive making noises?

  7. Step 7

    Look inside the computer for wires that aren't plugged in all the way or other faulty connections.

  8. Step 8

    Start the computer from an external start-up disk, such as the system software CD that came with your computer.
