blown theories and a revelation....
Ok, the temperature thing.. a problem, but not the cause of the crashes. They would still happen even at the lower end of the range. So... I found that I could intentionally cause a crash by repeating a process.. specifically overloading a plugin in photoshop. I updated it, and followed some advice on my memory allocation... no luck.
When I first got this system, I setup another user. That account never really gets used. I signed onto it, and have been working all day in photoshop, and intentionally trying to crash without success. My observations from the alternate account are that 1. The same if not more amount of services are running as my regular user, but, there are a lot less processes running. I'm thinking about copying the list of processes from the secondary, and paring down the main to match and trying to crash it..
So, that's where I'm at now, still troubleshooting, still learning, isn't this a great challenge??
