Here is my recommendation:

All in good faith. Been pulling for you. I know the feeling. The all nighters.
Keep trying. But, at some point cut your losses. If you have the money send the disks to professional extractors. $$$$
I agree with Sandeep. Get to 2012. Maybe Hyper-V. Get 32GBs of RAM. etc. But, I know you were likely there. Probably like I am.
HAVE YOU CHECKED THE PM. IT IS CRUCIAL. I can change the wording above.
