Hi,
My name is***** will assist you.
I am sorry to hear that you are having this issue.
This sounds like either the screen has failed or the Graphics Processor Unit. If the dots are moving then it is most likely the GPU, if the dots are stationary then the screen will need to be replaced.

This is an intermittent fault, after I updated the drivers screen cleared, these are not moving pixels but small green/blue dots all over screen, on researching on the internet there is something about overclocking - AMD Radeon HD6400 series - but sounds too complicated for me to fix can you assist?
