Hi all, I just got my brand new uMBP 15" 2.53 ghz about 24 hours ago. Unfortunately, I am running to a very annoying issue already. Randomly, my computer will freeze (the beach ball starts spinning and my music stops) for 5-10 seconds randomly. Since I started using my computer about 20 minutes ago, it has already happened 2 or 3 times. The last time it happened, I put my ear right above the HD to see if that could possibly be the perpitrator. When it unfroze, I heard the head move (or some sound from the HD). Anyway, has anyone ever of heard this issue before? I have been thinking about upgrading my HD to a 500GB, so this may just spur that decision along. Here is what was running when it happened: Unison (usenet program), itunes, safari, and pokerstars. Advice?
