I need help with my monitor. This has been happening for some time now. It doesn't seem to affect anything really. Its just every now and then these multicolored (yellow to gray) vertical lines will flash on the screen. In frequent 3-4 second intervals. It seems to be linked to aol and certain websites. What is the cause of this? Is it a video card issue?
check your vga signal cable for dry joints in video stage or check horizontal and vertical synch signals
