My kids PC has started switching from the digital output (connected) to the analogue outlet and back again. I have checked the monitor (Sharp -2 years old)by connecting it to another PC all OK. Then connected another monitor (one of those old TV things!)to the kids PC all seems OK. Took out graphics card and blew off the dust as the boys said they could smell that getting too hot electrical smell and put it back. Now checking again with a the TV monitor to see if any change. Had to re-image hard drive several weeks ago as had major problems following an interrupted Zone Alarm update. Do I have a dodgy graphics card Nvidia 6600 256 mb or something else.... I am a bit lost...suggestions
