Monitor Color problem

Everything is so much more darker or black then normal whenm i enter the web sites or anytihng with a sort of darkish color to it. I tried to this problem by using the 'color' , 'contrast' and 'brightnes' buttons when i enter my screen menue through the buttons on the monitor... No luck at all! i dunno what happend it started last night. :S maybe a button i hit on my keyboard? or :S Virus?

Any idea's how to fix it? I cant view pictures in their normal way since they have a reddish tint to it. everything just is annoying.

Example. Goto www.Roadrunnerrecords.com which is my home page and look at the color tone compared to mine

and this is mine.
