I tried re-installing Windows, and signs point to the hard drive being completely horked: the setup program recognizes the partition on which Windows had been installed as a non-NTFS disk with 100% free space. (Fortunately, most of the data--with the terribly unfortunate exception of all the writing she's been doing recently--are on a separate partition that would seem to be OK.)
So I'm trying to do a fresh install on the secondary HDD, so she at least has a machine to use. Problem is, since Pookie decided to "clean up" my computer area a few months back, I can't find my XP validation code, and have thus hit a brick wall in that process.
And I'm in full-on boards study mode, so I really don't have the time to deal with this shite right now.
I certainly shouldn't be wasting my time blogging about it, but there we are.
