For a week or two, my screen freezes: all motion, my mouse cursor, the video I'm watching or game I'm playing, everything stops dead for about five to 10 seconds. Except sound. So when I'm watching a video the screen freezes but I can still hear dialog. Then it unfreezes and the video has to catch up to where the sound had led in the video. Very annoying.
Anybody know what causes it and, more importantly, how to fix it? Short of a complete reinstall?
