This problem has been going on for about 2 months now, and FFXI is nearly unplayable because of it.
After a few minutes (it differs, sometimes 5 minutes, sometimes an hour) of playing the game, my computer just shuts down. This doesn't happen with any other application or game. I've been playing for almost 3 years, and this is a fairly recent problem. I've reinstalled FFXI with several disks (including the Vana'diel collection), but the problem persists.
Can anyone offer helpful advice? I really can't stand this.
