Hi it happened to me twice. Because I'd downloaded a different version of graphic driver which is not compatible with the current computer standard version. It will ask you to restart your pc to take an effect for the changes. And then after it loads I noticed that my screen is like getting bump and the colors are like changing very fast to purple,pink,black,green, (flickering) but I can still able to see my desktop icons.

This is my case. I haven't change any resolution. What I did is to try and try until I get the correct graphic driver version.
