Fs9 Problem, colors Options

[riversiderebel3]

Hello to all, about 2 months ago my simulator was acting weird but it somehow fixed itself. the color white turns to a weird yellow milkish color. You still see the white but except with a yellowish color. and also when flying through clouds or a storm, while inside the cloud, the clouds are yellowish. Do you think this is the fs9 acting up or my computer, perhaps the video card? Any computer wizz here that could help me out? Well thanks a bunch!!!
