    I am having the same choppy video problems on my G4 with 2 GB of ram running on Os x Tiger. I changed to a better video card but that did not help. It's sad that I can run any movie clip or utube on my Pentium 4 with no problem and Mac is supposed to be so superior for graphics, so they say. What is the deal?
    Is there a way around this problem?

The video is choppy because your computer is not powerful enough to decode the video. The imac g3 was a great computer in its day but it was never designed to run the graphically intensive programs of today. OS 10.4 already places a lot of demands on an older machine. Adding youtube video only exasperates the problem as there simply isn't enough processing power or memory to run the pretty aqua user interface of OS 10.4 and decode video at the same time.

Adding more ram may help (256 MB is not very much these days) but truth be told I don't think you will see much of an improvement given the low power of the G3 processor. Sorry to say it, but if you want to watch flash videos (youtube) with any level of reliability you are going to have to look for a newer machine. You probably could find a used imac g5 for a good price on ebay or maybe treat yourself to a new imac. Rumour has it Apple will be coming out with a new model in the next few days (weeks) so keep on eye out for that if your thinking of buying new.

    The iMac G3 has a maximum ram size of 512 MB of PC-100 SD RAM.

    Apple has relased new models of the Mac mini, iMac and Mac Pro today so if your thinking of a new one, now is a good time.

I have a similar problem working off of an ibook 64, 1.25 gb RAM, 1.06 gHz processor.

The video problem has gotten progressively worse. I used to be able to watch videos no problem, but now the video is choppy even though the audio is fine. This is the case for me no matter where the video is streaming from, the quality of the video, or the length of time my computer is running.

I also sometimes run into the problem where my computer is just very sluggish. It gets tripped up while I am trying to type, taking several seconds to register the characters I have typed or the clicks I have made. The problem seems to be worse when the computer has been on for a while or if the computer was not turned off properly (sometime by battery just falls out and my computer turns off).

Is it possible that this is a hard drive issues? When I upgraded my RAM, the problem went away for a little bit, but now the sluggishness problem is back to usual.

Apple imac g3 power problems

The power supply is probably bad and needs replaced. You will have to put a meter on the out side of the supply to know.

My mac is very slow. especially when playing videos. the videos are very choppy. is there anything that can be done to fix this?

Well, there are many reasons that may causing a Mac computer running slow, but generally two factors: hardware part & system part. For hardware part: I guess it's OK if your Mac is not that old. For system part: there might be a lot of junk files, caches, registry errors... out there which largely slow down any Mac machines. Actually about 80% slow Mac caused by this reason, if so, try cleaning the system. Learn more from: good luck!

Sound but no picture on my downloads i am using a imac

You probably don't have the right codec installed to play the videos you downloaded. Try installing Perian from This adds support for more types of videos.

If that doesn't work, try playing them with VLC:
VLC is a media player that supports nearly every format out there.

Jerky / stopmotion display on downloaded videos:

As time progresses, suppliers of online videos supply more resolution, and Apple updates your computer with QuickTime updates that take a lot more processing power. As a result, pretty much everybody who owns a G3 or G4 Mac now sees the same behavior you are seeing. The choppiness is do to you overtaxing your processor. It has nothing to do with your disk storage, or the speed of your router. The only good accommodation is to hit the pause control until the video has downloaded entirely -- once the networking code is no longer chugging, at least your computer can devote as much processor as it has to showing you the actual movie.

IMac G3 Not Starting

Hey, RexKing:

Your problem is hard to diagnose with your current description without knowing where the clicking sound is coming from or exactly what it sounds like, but most likely the problem resides either with the power supply or its connection to the circuit boards. If you have access to any scrapped G3 iMacs to cannibalize for parts at an E-recycling depot, you can probably find just about anything you need, as long as you get the right model, as they changed key components a few times, but, like cars, a lot of parts cross over. The exact model description is on the bottom in really fine print.

In any case, you will have to take it apart to check out the power supply and/or other components, which is a bit tricky without a guide. You can find a really comprehensive Apple iMac G3 service document, for many of the later models, posted at this URL as an 11 Mb PDF file:

Only catch is that to download it you need to sign up for a free SCRIBD account. (It's a document sharing co-op site.) Hopefully this won't result in years of spam. Good luck, and if you figure out the cause, please let me know. (I have about a dozen iMac G3s that I am gradually refurbishing.)

My G4 1.25ghz with 1 gb ram plays abc video slow.

Hello, sorry you are having trouble,
There are so many variables when it comes to Video play back on a Mac..
Yea, 1.25 Ghz with 1 GB of Ram answers most questions, yea, it should play OK,
  • Is the video on a CD or DVD ? well, these iMacs don't have a very fast optical drive.
  • How much room do you have on your internal hard Drive, if it's too full ( more than 80% full ) then you will suffer read/write performance.
  • Is the video on an external harddrive, is it a USB drive? the USB on the iMac G4 is USB 1.1, 11Mbit/sec, way too slow to play a big video smoothly.
  • Just what is the size of the video, is it like that for all of them or just one, might it be a HD video with high frame rates?
  • What version of the MacOS X do you have installed? If you installed Leopard 10.5 on the iMac G4, nothing will run smoothly,
  • Are you playing this video over a network? forget it it's got to be on the internal or a FireWire external disk otherwise it will stagger...
Well, there you go, I know, it's so easy to say Hey man, just get a new Mac and everything will be fine... But that machine is going on 6 years old now, Video technology has not stood still.....
