Which version of 10.4 are you using? There was a problem with 10.7 that had symptoms like yours. If you are using 10.7 try rebooting the PRAM and the goto system preferences and set the screen to 1024-768 and reboot. After the reboot you can set the resolution where you want it. Or just update to 10.4.11. Ralph

If you are not using 10.4.7 then I believe Chris is correct in his diagnosis. Ralph
