Frequent crashing to desktop

[BadEnlgish]

This issue has occurred for me since open beta. Since the latest patch, however, it's been happening several times per hour. Pretty much the only fix I've been able to research about this issue is shifting from windowed to fullscreen, and that hasn't worked for me. There doesn't seem to be any common occurrences in game that would point to a cause of these crashes. It happens in the middle of the Limsa markets, in Ultima, or just AFK in a low traffic area. I've tweaked graphics setting constantly, to no avail.

At this point, receiving help with resolving this issue will be driving my decision to continue paying for a subscription.

EDIT: I have also reinstalled the game on another hard drive on my computer.

Here is some relevant info from the game's system information app:
