Random, very inconsistent DX11 Error

[X89K1]

More notes on Solutions:
Fullscreen Optimizations are already disabled.
There are no unnecessary USB or audio devices in use.
Currently have yet to try the C:\ drive solution. FFXIV is currently installed on the D:\ drive, but there is a caveat. My user account data is also located on the D:\ drive, though Windows' core files are on the C:\ drive. I'm not sure if putting FFXIV on the C:\ drive would be more or less stable, given where user account data is.

If possible, could I have an explanation for why FFXIV when installed on other drives can cause crashes? Is this due to an error when trying to load something from Windows' core files(typically located in C:\Windows)? [8 April Edit: Fixed minor spelling error.]

Other Notes:
A review of a second crash dump was done, and it was found FFXIV had largely the same errors when other programs were not running.
