I've played this under dx11 for several months, and probably 3 months with my new build. Now all of a sudden i've been getting these errors after i reinstalled ffxiv onto my system due to a hard drive failing, (which is out the system now).

and MANY MANY MANY fade to black reboots. no error posts. "24" on my motherboard's error codes, letting me know it's in "working" operation.

here's a brief description of what's going on:
with ffxiv ONLY RUNNING. i can play normally for a random amount of time. no background processes are up asides from a hardware monitor. even then, i also tried it with that off. sometimes it errors out with a random dx11 error box with a bunch of the ffxivdx11.dll+XXXXX or the other nvwgf error variety. these tell me NOTHING of use.

researching, i've seen a few threads that have done all the things i've done.

things i've tried:
getting rid of the overclock.
getting rid of any custom nvidia settings.
reinstalling nvidia drivers (which made the fade to black reboots less frequent, still happen though).
reinstalling ffxiv completely.

i'm at my witt's end since a new raid is about to start up again.

here are my specs if that helps.

i'll be trying dx9 later (i really don't want to)
and i'm about to try capability mode with windows 7 on top of running it as admin.

i'm posting in case i get a cold reboot from running ffxiv and lose this post of my screen shots.
