My PC has dual gtx780's and they work fine when I play any Blizzard game/LoL/Dota2. I am even able to play COD and BF4 if I unselect SLI mode and only use 1 graphics card. It is only when I select SLI mode and load into either game (BF4 or COD) that my computer restarts itself. This happens when I actually join a game and not when I am in the lobby/settings. I have a 1000 watt power supply and there are no overheating issues. Does anyone have any ideas? I would really like to play these new games with both graphics cards. Thanks again.
