Recently, my LCD monitor started showing red and blue lines in certain areas of the screen, especially outlining images. I at first thought that someone had tinkered with the monitor display settings and made the reds and blues more intense, but I found that messing around with the color settings did nothing to get rid of these lines. My monitor then died a few days later (although I'm not sure if it's a coincidence), so I replaced it with an older monitor, and that one as well showed the red and blue lines, so I replaced it again with the same result. I figured that it's not a problem with the monitor because I took a screenshot of my problem, saved it as a .png file, and emailed it to myself on another computer, and on that computer the red and blue lines do not appear in the image. I have an NVIDIA GeForce 6150SE nForce 430 video card that came with the computer, and my OS is Windows 7 (64-bit). Any help is much appreciated, thanks.
