I've got a beige g3 with a reflashed pc radeon 7000. It is running 10.3.9 with 512mb of ram, and a 266 mhz overclocked to 300. It's been running very stable up until I put the radeon in. Then it would crash out on me at the apple logo on startup before the spinning thing comes up with the USB card in. When I take the USB card out, it works just fine. I've used this card before in this computer, and it worked just fine. Any suggestions?
