Since yesterday my Desktop W10 64bit has started acting weird. Randomly the icons on the screen and taskbar flash. I've also seen just the Cortina search box and Windows Defender icon start flashing too. Another weird thing is once it starts the letters C and S don't work on my keyboard.
I did install new software the other day and have uninstalled. I have also changed the registry and no help. Any idea whats causing this?
