    My G5 is running on OS X 10.2.7, duel processors, & 2GHz.

    I have always had trouble starting up my machine; I start it, but nothing happens on the screen, so I turn it off and start it again, 3-5 times until the screen comes on. I took it to the mac specialist and they couldn't figure it out. They said it was probably compatibility issues with the cheap-o screen I bought. Also when I put it to sleep over night it won't wake up, I have to restart it again, and when the room is cold G5 has a harder time starting up.

    Now there is a new problem. When it finally starts, the usual apple logo appears on screen as it boots, but when its done all that comes up is a completely blue screen. I can see and move the mouse pointer, but nothing else. No icons, no dock, no menu bar, nothing just blue. The tower makes a quiet, high pitch "bzzz...bzzz...bzzz" sound that I haven't heard until now. The sound comes from below the "On" button, the area I don't have access to at the bottom of the tower. I think it might be a short. What do you think?

    Sounds like you have a lot of problems, I don't think its your monitor, this sounds like either you have a bad HD, or maybe the logic board or processors are bad. Take it to a different Mac shop and have them fix it, have them hook it up to one of their monitors and see if that works, but I don't think that this is your problem.

    The problem with no video appearing on the monitor from a cold start, even though the computer has booted up fine, is a well known and widespread problem. Go to Apple's discussion forums and do a search for 'Black Screen of Death'. There are literally hundreds of posts about this. My 1.6GHz G5 also suffered from this. The monitor would never display anything when the computer was started first thing in the morning, and it would take anywhere from 2 to 10 restarts to get a video signal. Waking from sleep was also problematic, with the video signal not coming back to the monitor.

    The only solution to this problem is to have the video card replaced by Apple. They will do this for you under warranty, so there is no problem there. After I had my Radeon 9600 Pro video card replaced by an Apple dealer here in Sydney, all the problems I was having went away. If your current dealer doesn't want to be cooperative, try another dealer, or call Apple directly and explain the problems you're having. Like I said, this problem is well known...Apple should know what you're talking about straight away.
