I have the exact same card, and in order for it to detect it at all, I have to plug it in, but it automatically attempts to display the output through it, even though it doesn't have drivers installed, so it just casts a black screen. So I can't even use the auto detect software, since I can't see anything on screen. In order to see what I'm doing, I have to unplug my card from my power psu, but then it can't detect it. And I don't have the CD that came with the card, I got the card from a friend, and he hasn't seen the cd in a long time. So I'm quite literally screwed unless I can just download the drivers manually.
