Did you replace your power supply, when you installed the card. I think your power supply is only rated for 220 watts, like my Gigahetz Ethernet G-4. Almost all ATI cards more recent than the 9000 recommend checking the available power before installing. It is one of the marginal notes on the OWC web site.
