Try reseating the video card and make sure your monitor connections are tight. How long after you installed the new hard drive did the problem begin? Ralph

I just cloned the new hard drive a day ago, I did try starting the computer with old hard drive ., the same result and tried with another monitor= just black! unfortunately I don't have extra memory to test that theory :-((


oops forgot to ask (reseating video card?) how do I go about that?


Here's the URL for Apples support for the G5. If you download the users manual it has a pictorial layout for removing and installing the video card. Ralph
