When I start my computer the monitor flickers on and off. I have replaced the transformer and cable but the problem still persists. I have also selected a new refresh rate of 75 hz but this has had no effect. Can anyone advise?1 person needs an answerI do too

Did you check your Video cable at both ends (could be loose). Also open the case and reseat the video card (with AC power cord removed). Check for any dust bunnies in the card's fan and heatsink area.JShttp://www.pagestart.comNever be afraid to ask. This forum has some of the best people in the world available to help.
