Thank you very much for the detailed response, Tralfazz!
So, I set my graphics options exactly as you described with one exception--I did not change the screen resolution. Upon logging in a character, the game looked better than it has in years. That was no surprise since I keep graphics set very low as described in my original post. The computer fan immediately began to run at a higher speed. I turned in some tasks and puttered around the house.
I decided to run some missions and logged in a second client. I do this from time to time and was curious how it would go. The fan sped up some more but everything was fine as I ran some missions in Trestlebridge. Next, both characters traveled to Rivendell. Client 1 immediately crashed. There was no white screen, it just went *POOF!*.
I closed the client 2, launched client 1, set graphics back to very low, then closed client 1. I could not remember the original settings so I turned almost everything off. After doing that, I logged in both clients, put character 2 on follow, and headed across the bridge. Client 1 crashed halfway across the bridge, *POOF!*.
Well! Once again I closed client 2 and logged in client 1. I switched back to DirectX9 and closed the client. Then I launched client 1 and client 2 a third time. This configuration was stable when running missions for the rest of the evening.
Over the course of the evening I fiddled with more things as I closed and launched the client many times, often in pairs. Thirty frames per second was bothering me so I went back up to 40. I also raised one of the draw distances one notch so I can see enemies father away.

A couple weeks back, during a period of crashing, I read that lowering screen resolution really helps. You may have written the post I am thinking of. For two evenings, I set the resolution of my desktop to approximately 1300 x 900. I then did the same to the game. This worked for a time but, eventually, I experienced another crash. That led me down the road to killing XBox Game Bar.

Is there a way to save different graphics configurations, sort of how "/layout load/save blahblahblah" works?
My computer has 8 RAM. I forget where I found that.
