Since Heavensward, I've been having some serious power issues with my rig. At random times during gameplay, my computer shuts off completely. Then when it tries booting up, it'll lose power like 1-3 more times before it successfully boots up. This only happens with ARR. Being idle does not shut the computer down, nor do any other games. Went down the list of Steam games and none of them shut my computer down. My copy of ARR is not the steam version. Dunno if that matters.

Does XIV pull more power since HW or something? I built this computer right before 1.0 shut down, so it's only 3ish years old.
