I decided to try something really radical as the system was down so why not? I loaded BIOS vers. 4598 using the Recovery method and I'm now on-line using the DX58SO system.
My question now would be:
How new a version of the BIOS is safe to use and should I attempt to update again?
So in the meantime I guess I solved my own problem but it would seem there should be something to gain in updating besides trouble. It would be nice if there were a simulation that could be run on your system to prove compatibility of the BIOS update that wouldn't create such extream issuses as I had. Had I not been so "Bull Headed" and continued to try different versions of the BIOS I would still be using my wife's nice but inferior system and still be searshing for solutions.
