I lost focus of the original problem -- sorry! Sometimes I get so caught up in the jcgriff2 report I forget to read the history and miss obvious problems.

That is usually a sign of hardware trouble, and given the system history, again, I am not surprised. I'd suspect perhaps the hard drive is bad, or maybe the motherboard is damaged. I'd take the system into a repair shop and have the motherboard replaced, honestly.
You might try reseating your RAM as well; that's something you can easily do from home.
