iMac freezes when playing videos
I have read many posts regarding video freezing, but my symptoms are a little more than that. The playback of the video freezes, the sound continues, and my whole user interface is unresponsive. Usually within a 1 minutes or so, it all comes back. This behavior is very sporadic. Sometimes no issues for an hour yet I could get 3 when playing a 3 minute video.
I should note that I have had a history of issues with graphics - at different times, depending on the OS X update, I would get digital artifacts appearing. The severity varies per OS X update but for the most part still exits.
