OK, this is the situation: I purchased a refurbished 2008 Mac Pro 2 X 3.2 GHz Quad-Core Intel Xeon Tower with 4GB of RAM running 10.6 back in November. I installed a 2nd TB drive to use as a storage and Photoshop CS6 scratch disk. Immediately, I had problems shutting down, but that was solved by some technicians who I trust implicitly. I then installed another 8GB of memory for a total of 12GB and the machine ran like a dream for about a month or so and then the video card died. It was replaced under the warranty I purchased with the machine, but since the place is out of state (I'm in NY, they're in Georgia), I lost about two weeks during this process. During this repair, it should be noted that the logic board tested OK. After about a week of running great again, now it shuts down randomly. The light on the front of the machine stays on, as do the lights on the two 23" Cinema displays. It will stay on for a few hours, or an hour, or a couple of minutes and then...it shuts down. The shut down is not precipitated by the fans suddenly speeding up or any other over warning sign. It just unceremoniously shuts down.

I've had this machine since the end of November 2012 and it seems as if it's been down more than up in four months and it's really, really, REALLY frustrating. And and all help would be immensely appreciated.

Well, a quick visit to Tekserve revealed that it was the Power Supply that had gone awry. There was power coming into the machine, but it wasn't being distributed properly, hence the indicator lights staying on while everything else went blank. Now the machine runs like a dream again and am currently in the midst of setting up SuperDuper on an internal 2TB hard drive to supplement the Time Capsule (belt and suspenders, you know.)

So far, I've had to replace the video card, the power supply, give the machine's innards a good cleaning and repair permissions plenty of times. If anything else goes wrong, I'm not bringing it back to Tekserve. I'm not even going to send it back to the reseller who I originally purchased it from.

I'm going to an exorcist.
