    Yes I do get a chime and yes the screen is illuminated.

    Sometimes I get the spinning clock. That's all. No finder.

    Actually it was running OS 9. I don't have the OS9 disc but do have OS 8 disc and tried starting up off that disc with the same results. There's nothing on the hard drive that I want to save. I really want to clear it so I can put it in the garage sale this weekend.

    Yes I know, anything before OS X is hard to recall.
    Like I said, just trying to unload the old clunker for a couple bucks.
    I tried that, and reset the P-ram and rebuilt the desktop. The most I get is some icons on the desktop but still no finder.
    What do you think about the battery? I hate to spend the $20 to replace it for nothing. I don't expect to get much more for the old machine anyway.

    Hi there
    Just a quick question. Do you get a start up chime? Is there any illumination coming from the screen?

Sounds like a system error. The only way round this is usually to start up from your original OS disk.

You have quite an old mac (relatively speaking) and sounds like you are running OS 10.4?

Try starting up from the disk. You should then be able to see your drive. If you can see the hard drive you might back up important files now (if you can connect a external hard drive) The first thing is to try and repair the OS on your drive with the apple disk utility on the disk. You'll find that in the drop down menu. If it cannot repair you will have to re-install the OS. Archive the old system and install a new one. A clean install is usually better. Then get all the updates.

With your machine you will be limited as to what OS you can put on it.

    Blimy going back to OS 8 is to far.

    It's been a while since I worked in OS 9 but as far as I can remember if you hold down 'shift' key on start up will switch off all your extensions. The mac should then boot up. You should then be able to isolate the extension that is causing the problem. You can do that in the control panel 'extension manager' switching back on what you need to run the apps you want to use.

    If all that does not work the only option open is to get hold of an installation disk you could download it on another machine and create the install CD.

    Sorry I cannot be of much more help.

    I see what you are trying to do.

    I thought you where working on a G4 tower? The only battery in that is the clock battery and that is very cheap? Or are you talking about a powerbook?

    As far as Icons on the desk top and no finder. If you hit option 'F' key does good old Sherlock come up?

    I don't wish to sound stupid but with OS 9 the finder being crammed in the right hand corner I have seen cases where the monitor has been set incorrectly and the finder has been pushed of the screen to the right. Might be worth taking a look at your res'.

    If you are looking to get it working and resell. There are a lot of mac enthusiasts out there that are willing to buy a old machine. I imagine if you spend $20 you'd like to get a bit more than that back.

    Someone might be willing to pay more if the machine is running OK. If you sell it to a mac person it might not be worth the investment as they more than likely could sort the problems out and would take the machine as is.

    If you are going to sell I'd try as is first to se what offers you get. Then look at investing some cash in fixing it up.

    Sorry, that's about all the advice I can offer. Good luck.

I tried to hook up my power mac g4 tower to a monitor and the screen is not coming on. It states monitor is on, now connect to computer.

Really, the only way to troubleshoot this problem is to connect your display to another computer and see if it functions; then connect your computer to another display and see if it functions. Once you have determined which unit isn't working correctly, you can proceed from there.

Several months ago my Mac Mini G4 stopped recognizing both the internal hard drive and the optical drive. In the system profiler nor Disk Utility nothing is recognized under the ATA bus. I have been...

Hi, has this mini been opened up to add more memory?
I would suggest that before you conclude that the ATA bus is damaged, open the mini up and see if the ATA connector is still connected to the motherboard. (It's the same connector for both drives).

I would say there is a bad ram stick in there. If you have more then one take one out then restart if nothing changes try the other.
