Ive just bought a new Radeon 9800 pro. I have downloaded the drivers etc, but when I connected the card to the AGP port, and switched the PC on, it doesnt do anything, apart from powering up the fans and the power lights. Im thinking this has somthing to do with how the power cable is connected, im running it in a chain from one of my CDR drives. Is this right? Before I had a GeForce MX400 and I havent removed the drivers? would this effect it? if so, where do I get the correct driver to 'see' the card?
