Understanding faults in computer system

The Computer Won’t Start

  • A loose connection is a common culprit; check your computer’s power cable is securely connected to the plug socket. If that doesn’t work, test the plug socket by connecting a device you know is working. If it no longer works, the problem is your plug socket.
  • If your computer will turn on, but suddenly shuts off could have a failing power supply. 

Blank Computer Screen

  • If you know your pc tower is working but the screen is black, there is likely a connection issue between the tower and the screen. 
  • Firstly, check the monitor power cable is securely connected to a plug socket. Then check any cables connecting from your pc tower to your monitor – these kinds of faults are usually due to loose connections.
  • If you’re having the same problem, but on a laptop, then you will need to take it to a professional. The internal cables may be worn.

Unresponsive or Malfunctioning Operating System or Software

  • When your operating system (e.g. Windows) becomes unresponsive or malfunctions, the first thing you should do is a simple restart and virus scan. You can avoid running into this problem again by installing reliable anti-virus software.

Windows Won’t Boot

  • If you’re running Windows 10, you can use its Startup Repair function to fix problems that prevent Windows from running. Access this via the Windows 10 installation disc or a flash drive.
  • After inserting the disc or flash drive into your PC, give it a reboot. You should now boot to and follow the on-screen instructions through to ‘Repair your computer.’
