rules that out then, try updating to 511.23 released today, i've put ffxiv through the paces and had no stability issues, i never tried any of the 496 drivers because of reports of stability concerns on older systems.

If you happen to use any third party tool for screenshotting, these can corrupt ffxiv memory and only result in a client crash hours later.
