I gave up on most telephone tech support a long time ago, when I realized that I was almost always more knowledgeable than the person on the other end, who would usually waste my time walking me through everything I had already tried.

When I run into a problem I cannot figure out myself, I turn to the various online forums. I have had far greater success solving technical problems in this manner than I have ever had with any tech support helpline.

If you still haven't resolved the problem, I suggest that you get hold of a Knoppix disk, boot it, and attempt to recover your data files. Knoppix is a "live" CD that boots a Linux system directly off the CDROM into your computer's RAM. You then use the tools on the Knoppix disk to transfer your data files to a USB pen drive, another hard drive, etc.

Once you have done this, you can then "wipe it out" and reinstall Windows.

You do not have to be a computer geek to do this. Below is a link to a website describing the procedure in great detail in non-technical language.
