Need a little computer help

[Murminator]

ok I have this problen on my screen everything look blue like there is a 20k bulb running it. All my whites are blue/white and I have no greens I know this guy is green but on mine he is grey
I have played around with all the color settings on the monitor and in graphics option nothing. I can make a little better but everything is blue
I did have a screen saver download from the web for about a week but I ended up not liking it so I removed it today now I come back to my computer and it's blue coincidence? or is my monitor going?

Help ????
