I have a CTX monitor that is six months old. I know its okay. I also have a Matrox Millenium 4 meg video card. Once a week my monitor will change color schemes. Things that were cyan blue turn to magenta and so forth. After a few more seconds everything starts to get fuzzy and lines begin to appear. At this time I reboot the computer and its back to normal. What could this mean? Is it a virus? Do I need to reload Win95?
