So I bought this used 9700pro off ebay, guy says it was in a working system and the card was working when he pulled it. My problem is I can't get a picture. I tried it in 2 different systems with different mobo's etc. Same thing happens, pc boots up and probably goes all the way into windows but I get nothing on the screen, not even a "signal cannot be found" message or anything. I believe it's hooked up right, even connected that little 4pin one to it. Card also seems to be running well, no weird noises, fan looks okay. Any ideas?
