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?
Thank you - looking forward to hearing from someone soon
No - I have tried resetting my pc back to factory settings, but still these dots appear, I can now only assume that there is a problem with my pc and cut my losses
No worries, there is a problem with my pc and an engineer is calling today to fix it - I don't need any further advice from you
