Windows 10: Little grey dot on screen?

Hi. there is a small dot on my left monitor only when im in the homescreen and it covers apps but not my cursor? I have a Asus ROG STRIX G16CH_G16CH prebuilt PC and have tried updating my drivers already uninsalled apps that may have been causing a problem? Photo is attached of the dot

HD5770 grey screen problem

My Grey Screen was caused by bad memory. Changed the memory and everything has been good for over a year. What i mean by this is that Grey Screens are not black and white to solve they are in the grey area. There are alot of different components within your computer that can be causing the grey screen. If you can i would RMA 1st though because the GPU may be really sensitive to your system. If you still have issues after the RMA got for overclocks and RAM.
