Sorry to be slow in getting back to you.

I am attaching two zip files. One is ChkDsk results from 3 days ago for all of the logical drives on my HDD. The other includes a decoded memory dump from a BSOD today (which explanation added of what happened), results of an automatic ChkDsk on drive F: that ran when I rebooted after the crash, and a ChkDsk /r that I ran after that one on the same drive.

The BSOD today said "memory management". In recent days, this is the second crash I have had that ran a ChkDsk of F:. I know I lost two large groups of files either on the first automatic ChkDsk a few days ago or one of the runs I did manually in that timeframe with ChkDsk /r.

On today's crash, Copernic Desktop Search in pointed in the dump file a likely cause; however, its index files are stored on F:. This is the first time that program has shown as a possible cause, and over the other BSODs I have been experiencing it is one among a mix of programs indicated.
