Question: Just out of curiousity I ran the Apple Hardware test on my Intel iMac and it comes back with three different error messages each time I run it: 4MOT/2/40000004:0x3cdba710, 4MOT/2/40000004:0x3cc5BF90, and 4MOT/2/40000004:0x3c239410. I haven't been experiencing any problems with my machine at all...runs perfectly. Called Apple and they suggested I zap the PRAM and unplug. I did this but the error codes remain. Any ideas as to what these might indicate? If it's the logic board, which I suspect, how can my Mac still run perfectly without displaying any problems?
