This is the part that most respondents have missed. **** Prior to installing the RAM, I was plagued with crashes ***** So the original RAM may have been faulty. A good memory test run for a week or two might help confirm or deny this. But if the machine was bought new, it would suggest that something else is faulty. No amount of swapping RAM in and out, or arguing about the quality of the RAM, will alter the fact that you need to debug the machine with its original RAM and get it working reliably before you contemplate an upgrade. Unless of course all Mc Minis show the same symptoms ...! -- Gaham J
