I have a gold series 750W corsair, but when I launch a game the 2nd card is still unpowered. Could it be because the one card is enough to handle the game and the 2nd card need not turn on?
But also I ran a GFX test off of Furmark and the 2nd card still didn't turn on.
I had some help from a friend in which he "Confused" my computer into turning on the 2nd gpu and now it does work alongside my 1st gpu. However, when I update the drivers, I find that it happens again, my 2nd gpu doesn't turn on, so I system restored and haven't updated my drivers at all
