I've had the same issues as everyone else, since ARR was released. Random crashes and occasional BSOD. Here's what I've tried that has done nothing at all:
  • Updated graphics drivers
  • Tried old nvidia drivers
  • updated BIOS
  • tried default BIOS settings
  • Reformatted my hard drive
  • Installed Windows 7 64-bit, Windows 8 and Windows Vista (none made a difference)
  • Did a memory check, a disk check and a stress test on my GPU
  • Both my GPU and CPU temps never go above 45C
  • I've tried disabling unneccesary Nvidia services
  • Updated my OS completely with Windows Update
  • I've tried fullscreen, windowed, windowed borderless, max settings, minimum settings (on graphics)
  • I've tried using only onboard sound, I've tried using only Nvidia sound
  • I can run any other current-gen game on max settings for hours and have no issues. I'm lucky if I get 30 mins in Final Fantasy: ARR

I've seen several people on here that are adamant that it's not the game causing it, and that a BSOD is hardware, blah blah blah. The blue screens are usually caused by memory errors. Memory errors can ABSOLUTELY be caused by a program, thus causing the BSOD. Somewhere in this game there's poor memory management. The number of people being effected by this is growing daily and there seems to be no fix in sight.
