Screen/desktop color changed to a greenish hue...

Hello everyone- We just got this new computer 1 week ago, & have been very excited to experience all it can do. All of a suddent today, the entire desktop/screen changed to a greenish "hue"... the wallpaper & icons are all there, but the whole color cast changed. I have tried going into the settings, I even did a System Restore, but it is still this overall greenish color... any ideas on what caused this & how to fix it? Thanks

Hi Hwyrun

Take the unit back to the retailer.
