Onboard video card faulty on laptop

If you have a laptop or notebook computer and notice strange things going on with the display on your machine, you may have a faulty graphics chip on your laptop's motherboard.

This is a reasonably common problem, which affects certain models of machine more than others.

It can cause a number of different symptoms, including:

  • Multiple Images / Duplicate Images
  • Random Characters on the Screen
  • Lines on the Screen
  • Distorted Video
  • Video Freezes
  • No Video On The Screen
  • Scrambled video
  • Vertical and Horizontal Lines
  • Flickering Action
  • Intermittent Booting
  • Blank Screen
  • White Lines Running Across Screen
  • 3 Beeps

The problem is usually caused by the cooling system in the laptop or notebook not working well (or perhaps being clogged up with dust and grime). That means that the graphics chip heats up so much that it becomes partially detached from the motherboard causing the problems listed above.

This problem can sometimes be fixed by using a process which reattaches the chip to the motherboard, however you also need to address the underlying problem of the computer overheating to prevent it from happening again in the future. This might be achieved by cleaning out or replacing the fan unit(s) in your laptop.

If the VGA chip repair isn't successful, then the other option is to replace the whole motherboard  - depending on the model this can be reasonable or quite expensive.

Our best suggestion is that if you're having graphical glitches like those listed above with your notebook, then let us take a look and we can give you an assessment and quotation for what it would cost to get it fixed. Sometimes it is even simpler than a VGA chip repair - it could be something as simple as a new loom (the cable running between the base of your laptop and the screen).
