Windows 10: Grey screen on bootup even after full computer reset.

I reset my entire computer, choosing to delete all my personal files and when I boot into Windows there is still a grey screen and I can't do anything besides move my cursor. I try to do the startup repair but it says it cannot repair it. I try to boot into safe mode but there is a logonui.exe error and it won't let me do that either. Also my keyboard which has never had any issues up until now is not functioning properly and I have to press on the key around 10 times before it types anything.

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.
