I've had my MBP 2.3 15" for 5 days.

It has now frozen or locked up about 6 or 7 times.



Each time, the fan(s) were spinning audibly.

Last time it happened I was running Handbrake converting video.

Machine froze, no mouse movement - completely "dead" and had to hold down power button to shut off.



Twice it has happened when running BioShock - in this case, in one instance at least, I Apple/Tabbed out of Bioshock to go into finder and do something and the screen went black, OSX seemingly unable to "get out" of Bioshock and the whole thing froze - ALT/APPLE/ESC etc did NOTHING.

Had to hold down power button again.



Also, I have had similar behaviour, when fans were spinning loudly and thus, presumably the machine working relatively hard, but the mouse would stay responsive to movement but clicking did not work for anything. Again, Apple/Tab etc would not work, could not force quit anything - effectively the same problems as above, but the mouse would at least move.

Only way to fix = hold down power button.



In each instance, the machine started up fine, immediately and most recently (such as right now) I am running Handbrake again and typing this post, and the MBP appears fine.

Thus, the problem does NOT occur everytime the CPU/GPU is under load, but it HAS ONLY happened when the CPU/GPU is under load.



Rather worrying and I will be talking to Apple first thing Monday morning!
