The computer being posted about doesn't even have an ATI card, so that's not it.
It was a failing hard drive issue, as the system crashed two days later. The storage drive was not at fault, but rather the OS drive. Something is the OS was causing the written files on to storage drives to have some kind of odd inconsistency. So only the original system with the error, as well as (thankfully) a Linux Xubuntu system. Using Linux, the files were 100% recovered.
So this is just a coincidence.
