BSOD

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.

Code:

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.

When it comes down to it, you might just be better off. A new motherboard for your system would cost probably a couple hundred dollars, and there is no guarantee it will solve the problem. If you had access to spare computer parts you could test with, it may change the story a little. If you could definitely rule out RAM and CPU, we could make a pretty good case for the motherboard being the problem.
