Hi, I have windows 7 and I can't fix this problem. First the screen colors changed to only blue and yellow colors, which made the color red appear black. Then, while trying to fix it, the entire screen turned blue tinted and now I don't know how to change it back to its original colors. I've tried personalized settings. I've tried screen calibrations. I've tried changing from 32 bit to 16 bit, but nothing works. Please help me
