When everything is loaded and the system is quiet (no hard drive action)the blinking stops. I can force the blinking off and on by moving the mouse back and forth quickly over links.
My computer screen consistently blinks off and on when booting applications are loading or when scrolling through pull down menus or when web pages change or when parts of web pages are loading. Sometimes it will do the same when I move the mouse too quickly over links, but not always. Any help? I have Windows XP Home.
