Well about every ten mins the screen will go black for about 2 seconds then turn back on.
OMG, thank goodness, you have this problem too. I thought I was having a black-outs or a stroke or something. When you get to my age you can't be too careful. And seeing as I don't have a long time left on this planet, did anyone figure out what's causing this yet? I have only tried one monitor so far but my hunch is its AMD's on-board VGA controller having a hard time at 1920 × 1200. Anyone figured it out yet?
