Flashes almost black you say? Does that mean it's dim or completely black? If it's going dim, possibly a problem with the backlight or the switch that turns the screen off when you close the lid. Just a thought anyways, I'd try booting into safe mode, if it doesn't happen there, try reinstalling your video driver, or maybe disabling power management.
hey all... i have an emachines m5105 laptop. i just reinstalled windows xp professional on it, went through the whole process, everything was fine. i installed windows updates, all the emachines drivers, then aol messenger, a couple of simple programs, then adobe dreamweaver, reader, the google toolbar and microsoft office (in that order). by the time i was done, the laptop screen flashes to an almost black screen, on and off, constantly. i uninstalled office and dreamweaver, since that was not happening before i installed those programs, but i'm still having the same problem. anyone have any idea what may be going on?
