I know nothing about what you are asking but found this online:
Visual Anomalies
The GPU handles the rendering duties for graphically intensive programs, so if it cannot perform adequately any more, visual anomalies such as artifacts, flickering images and a blank display can start to appear. If you notice wrong colors in the visuals or lines appearing across the screen, it could be an indication that the GPU is failing. Check that the graphics card is properly seated and that all cables are connected to ensure that these issues are not responsible for the visual anomalies.
