Create a new user account and see if the problem persists. If it goes away, it indicates a software problem in your main account. If it stays, it's probably a hardware issue like a worn video cable. The latter would be an expensive repair.

1st gen imac g5 graphics problems

Hi-
I have a first gen 1.8ghz 20" imac g5. About a year and a half ago, the mother board was replaced because of the exploding resistors. Recently, the screen has started intermittently getting pixelly in spots (like it did pre-mo-bo replacement) and then freezing (which is new). It happens every day or two, or sometimes within 10 minutes of booting. It seems to happen more quickly when Safari is up strangely enough...
I took it to the apple store this weekend and the genius there said that the resistors were not exploding and that the mother board looked good. I haven't seen any drivers for the graphics card available. Wondering if anyone else has had this experience and if there is anything that can be done. A shame to have to do away with this thing...

HI,
I too have a 1st gen iMac G5 20". It too recently started showing artifacts on the screen. For example when moving a window parts of the screen would get messed up. The problem became worse to the point where it would get stuck on a blue screen during boot (mouse and pointer still working). I took the cover off and saw three leaking capacitors on the mother board. They were in the group of 5 near the middle bottom of the board. I had them replaced, but unfortunately, this did not fix the problem or improve it in anyway. At the moment I have no idea what the problem is. Is this in anyway similar to your problem?

No video whatsover G5 1st gen iMac

My friend got this pristeen 1st gen iMac for free at a 2nd hand store outreach center. The HD and ram were missing and a I T tech we thought knew told us that was all it needed. I had no experience with anything Mac but I'm willing to learn. After installing 2 Gb of new PC 3200 400 mhz ram,new Western Digital 320 Gb 7200 rpm 32mb cache Sata hard drive, new apple wired keyboard,new Turtle USB Mac mouse and the brand new OS X Leopard disc and..... no video! I'm thinking this needs a replacement mobo but the mobo and capacitors are all looking great(appears new) so I don't think they're the problem. If I'm missing anything obvious please help. Possibly there's a video card missing and I don't realize it yet. Otherwise I'll be looking for one of those replacement G5 mobo's or a trade plus difference deal for another refurb or used Mac. Any ideas?

Is it starting up, but with no video? Or is it not starting up? I'm not certain an iMacG5 will handle a SATA disk drive successfully. Another possibility is that whoever had it before saw it die, salvaged the HD and RAM, and junked it. Sometimes you get what you pay for! You could get an external case for a SATA Hard disk, and maybe find someplace that would take the RAM in trade for some that's right for a new Mac, and be ahead to just buy a new one. If you're like me, I HATE to see one bite the dust with no hope of resuscitation!

Choppy video playback on my 1st Gen iMac G5

Everything from internet video to DVD playback on my 1st Gen iMac G5 is choppy and getting more so as time goes on. Can anyone tell me if this is a symptom of the defect that's covered under the extension plan or is this just some other problem?

Check the version in the Application Folder!
(I have had no problems at all after installing QT 7.5 on my G5 iMac in case you think it can't work at all.)
It is possible that something in either your pre-existing setup or your method of installing updates, are the root causes of whatever problems you are having with QT 7.5 particularly with choppy playback. Out of date plug-ins and add-ons could also be playing a part. Some users have found choppy playback to be associated with improperly loaded plug-ins and add-ons from third party vendors as well as those included by Apple with prior versions of Quicktime.
Third-party add-ons include DivX, Flip4Mac, or FLV components, while the included plug-ins are AppleIntermediateCodec.component, and AppleMPEG2Codec.component. The files for these are located in the root library, therefore a faulty component will load improperly for all users, resulting in choppy playback even when a user creates a new account. Some may need updating or just reinstalling to work with QT 7.5.
You should therefore:
Remove and re-add all quicktime components and plug-ins.
Navigate to /Library/QuickTime/
Move all plug-in ".component" files from the folder (to the Desktop, for instance)
Launch QuickTime and quit it again
Place the ".component" files back in the QuickTime library folder
Launch QuickTime again, and the choppiness should be better.
A few more things to try but in each case first close all applications and repair permissions.
1 Try opening then closing GarageBand, or launching then quitting the "Audio MIDI Setup" application located in Applications/Utilities. Failing that, go back to Audio MIDI Setup, and under the Audio Devices tab, make sure the Audio Output Format is 44100.0 2ch-16bit.
Restart your Mac.
2 Go to the Library on your main hard disk and find the Internet Plug-Ins folder. Try removing the following files:
QuickTime plugin.plugin
Quicktime plugin.webplugin
Restart your Mac.
Re-install the Quicktime 7.5 update
Go to Home/Library/Receipts and delete the file Quicktime 7.5 pkg.
Download from the Download page on the Apple site the correct version of Quicktime 7.5 for your Mac.
Install it and restart your Mac. Repair permissions.
3 If still no luck, it is time to look carefully at your plug-ins and add-ons. The safest way is to download and re-install all of them. The ones you need in order to see and hear virtually everything the web has to offer are:
RealPlayer 11 (which is no longer in beta) for Mac from:
http://www.versiontracker.com/dyn/moreinfo/macosx/15540
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
Adobe FlashPlayer should first be uninstalled using the appropriate uninstaller available here: http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157&sliceId=2 and then the latest version obtained from here: http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash and installed.
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.)
You should also ensure that you have downloaded and installed all the correct version for your Mac of all recent Security Updates.
(N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
If none of the foregoing worked, then you should consider and archive and install before repeating all of the above.

1st Gen Imac G5 Question

I own a 1st Gen Imac G5. I just recently purchased the Apple VGA Display Adapter hoping I would be able to use an external monitor as an extention of my desktop... after looking through the system preferences I realized there was no such option. I thought it might have had something to do with the OS version I was using so I upgraded to Leopord thinking it would solve my problem... it did not. Is there any sort of Patch or possible solution that could solve my problem?

1st gen iMac G5 Crashes and Won't Boot Up

To whom it may concern :
I've been having problems with my 20" iMac G5.
It frequently freezes and a message that says I have to restart my computer by pressing the power button for a few seconds appears.
At first, after I've done as the message said, my computer booted up successfully and after startup a message that says "Mac OS X quit unexpectedly" appeared, although when I pressed Report it did nothing.
For the past few days, the same as above occurs except when I try to boot up my system it starts booting up and freezes on a black screen while the computer backlight is on.
If I'll leave it on in this state for a minute or two, the fans will begin spinning at maximum speed (I believe so due to the great noise and mild dust they will produce when doing this).
I should state that it freezes randomly and not after a specific action: when I multi task, when I return to the computer after being idle (screen saver or the monitor was off) or even when no programs are running.
Does anyone know what's wrong with my Mac ?
Please Help !!

1st Gen iMac died-cloned HD onto new iMac-software needs to be deactivated?

My old G5 iMac (1st gen) died - capacitors. The Genius Bar confirmed and in a thoughtful gesture removed the HD so that when I purchased a new iMac it would be easier for me to transport the HD & for them to clone (he said they would do it free).
There's no way I could afford to buy a new iMac. eBay to the rescue: I purchased a used iMac G5 17", 2 GHz, 2 GB ram, 160 GB. (A little step up from the old 17" 1.8 GHz, 1GB ram, 80 GB.) I took it to Tekserve; they charged me $60 to clone.
Everything is hunky-dory. Knock-on-wood, the eBay used iMac is working fine (this is still the first week).
Today I launched Photoshop to discover that the app would be valid for only 5 more days! It seems that I am limited to 2 users: my old iMac and my laptop. If I deactivate the old iMac the message says I can activate the new iMac as a user.
Make sense? But my old iMac is just a chassis and a separate(d) HD. How do I communicate with it to deactivate it as a 'user?'
(1) Am I going to need to take my old HD back to Tekserve (auth service) within the next 4 days and have them hook it up and deactivate?
Since my new iMac is cloned & running & backed up, I was thinking of erasing the old HD and selling it for parts.
(2) Is there a way for me (I'm not very technically savvy) to erase my old HD that is separated from the iMac and sitting in an anti-static bag in order to sell it?
(3) Is my best option to have Tekserve do both: 'deactivate' and then erase it? Their charge will impact the potential profit I might make selling it for parts...
(4) Short of me launching every software app, are there any others that, in your experience, will have this same 'deactivation' issue (before I erase that old HD forever)?
Thanks to all esteemed gurus for any and all advice!

I ididn't think Adobe would be helpful. Nut lo & behold, they were understanding and I was able to activate the software on my cloned iMac.
I didn't think it could be so simple!
Meanwhile, I have taken the old 80 GB hard drive into Tekserve for a clean install and will put it up on eBay for parts/repair along with the 'chassis.'

1st gen iPod flashing screen

I have a 1st gen iPod. When I went to connect to iTunes to sync and charge my iPod, iTunes does not recognize it and the iPod is flashing the apple logo. Otherwise it does not power up at all. It was used as recently as the night before with no issues other than needing to be charged. Suddenly it appears to be dead. Help!

Yes. The screen in one model/generation iPod are the same.

1st gen ipod dim screen

hey guys,
i have a 5th gen ipod that i mainly use but i like to tinker with older ones. i just recently got a 1st gen missing its battery, my friend wired the battery plug-in to a car phone charger and used it for a little but then gave it to me. all it needed was a battery and fire wire(as far as i knew) but today i got a brand new fully charged replacement battery and when i plugged it in.the screen was so dim i didnt know it was on till i figured out how to activate the backlight. it was the wierdest thing, with the backlight on i could sorta barely see the text and with it off the screen looks off. im sure this isnt a five r problem but i was wonderin if anyone knew what this could be. PLEASE HELP!!!
thanks
tony,

You can try the following but I suspect a hardware problem
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
Apple Retail Store - Genius Bar
Apple will exchange your iPod for a refurbished one for this price. They do not fix yours. I would say not worth it for a 1G
Apple - iPod Repair price
A third-party place like the following maybe less. Google for more. Also likely notr worth it.

1st gen iMac G5 resurrecting from the dead? (strange clicking sounds)

I have a first gen iMac (pre-iSight) that I bought a few years ago brand new. But the past 8 months or so I've been having a very strange power problem where occasionaly pressing the power button does absolutely nothing... WAIT! I know you hear about this problem all the time but before you click 'back' I'll have you know I too have read countless of these types of power problems on forums, but this one seems different!
Sometimes after unplugging, waiting for a few minutes, then replugging the power supply (while all other cords disconnected) it'll all of the sudden turn on. I recently checked inside the computer as one tutorial suggested to see if the first of 4 LED lights turn on when plugged in, and it does, meaning it's not power supply failure. The biggest problem with the whole thing is that is that the "unplug-then-replug"(sometimes upwards of 15 times) doesn't always work, and always seems to happen at varying degrees of inactivity depending on how long the computer has been off.
I've been doing this for 8 months, afraid to turn my computer off not knowing for sure i'll get it back on (which can take up to a day sometimes). And my resurrection methods seem to be more and more futile, as today and yesterday i've had no luck. LASTLY -- and this really confuses me -- I usually hear a very faint but rapid clicking noise when I plug in the computer (before I even turn it on, never happens when it's actually on) after its been unplugged for a while. The sound seems to be coming from near the bottom of the computer, so I cant imagine that it's that dreaded "Hard-drive Death" symptom (since the hard drive isnt even running).
Please, if you can, offer me some insight regarding these issues, I've looked everywhere and it seems I'm the only one having them! I'm almost to the point of gasp! actually finally going to the apple store and paying them to fix it.....

Hmm, the fan? How would I go about checking that? I want to try everything I can.
DEVELOPMENT: I got the computer on last night (using it right now)! I think it was off for almost exactly 24 hours since the last time I had it running. The most frustrating thing is that I don't really know what I did differently to get it to boot up again. That whole day I was just checking it about every hour or two, unplugging and replugging the power (at one point I opened the back and tried pressing those two tiny buttons under the fan, one is an internal power switch, and the other some sort of reset button, nothing noticeable happened with either, although the clicking sound that occasionally showed up hasn't reared its head lately). I think my computer is almost at its end, and now that its on I'm going to try my best to keep it running. One more slip into a coma and it might not make it out...

1st Gen iMac G5 BAd Power Supply

Hi, My iMac G5 power supply is officially dead. It was confirmed at the Apple Store at the Genius Bar. Apple apparently no longer sells the power supply for the first gen iMac G5s. I have two questions: Does anyone have a suggestion on where to buy a 3rd party power supply for that model? I'm not exactly sure what I should be buying. And secondly, is it worth it to do? I know the second question is more opinion but I'm curious of the success rate of replacing the power supply. My preference is obviously to replace it rather than laying out the money for a new iMac which I probably can't do right now) but if anyone's experience is that I'm just throwing money away on the power supply because of future issues or unreliability, I'd like to hear about it.
Thanks as always!

[Synaptech.com] or [welovemacs.com] will not only sell you the correct part, they will give you installation instructions. Another source is [http://www.jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php]
As to your second question, as long as the rest of the Mac is in good shape, replacing the power supply should give you a few more years to collect your pennies for a new one down the road.

1st gen imac,dual core no power? Some helpful advice requested please....

Please pardon my grammar, sentence syntax and perhaps spelling!
Yes I have read all the gloom and doom posts regarding logic boards etc, what are the chances it might be a power supply issue?
Cord in and out, pram reset, no power light, no response to keyboard, no connected accessories, nothing on screen, no response to attempted insertion of disks, so sound (start up or otherwise), no sound of disk trying to boot etc, etc. Tried alternative cord as well...rarely shut down except for moving unit, days away etc
Please could you helpful guys and girls throw some ideas about what my issue with this rather old (first intel imac early 2006, 2o" screen) but beloved piece of tech might be?
My Imac simply went to sleep one fine spring morning and never woke up. Thanks in advance!!

I am on the phone right now with a product specialist about my iMac G5 power supply issues. Kind of ***** because he has, in so many words, said that the Genius is the Alpha and Omega and can extend the 3 year coverage. For me that is great except that the Apple store is over an hour away. I don't understand why the dude on the phone can't pull the switch and make it happen as well.
Factor in:
Unplugging iMac G5 and all peripherals
Loading it in the car
Driving an hour
Carrying it into the Mall (apple store)
Waiting for my Genius appointment
More than likely getting it fixed for free (from the sounds of things)
Driving back after it is fixed
Doing everything listed in reverse.
Would it just be easier to pay the $108 for a new power supply, wait a few days, undo some screws, and BAM! it works again?
Update. Off the phone now. The product specialist flexed his muscles, back handed the Genius to gain authority, and basically stated that they WILL DEFINITELY repair either the power supply or the logic board or both if needed. I have already had them replace the logic board once. BUT, I still have to load it up and take it to the Apple Store. Boo.

Procuring and installing a bluetooth card for 1st gen imac G5

Hello,
I'd like to install an internal bluetooth card on my early G5 iMac. Can I do that? And if so, how would I go about it?
Thank you so much,
Sincerely,
Tabeer

There are three things you need to install the Bluetooth card on the iMac: the card, the antenna, and a small bracket for the end of the antenna.
I looked on the web just today to find the answer to that and most all said it can not be done. I just installed one on a 1.6 MHz G5 iMac. I piulled the components off a 1.8 MHz G5 iMac.
You need to be comfortable opening the iMac. I had almost nothing to lose here because my 1.8 MHz failed (capacitors) and I had done quite a bit to try to resurrect it - I had the mother board out of the machine. Interestingly, to do this operation, you actually do less dissassembly than taking the mother board out. The trick is to leave the mother board in the frame, and remove the frame from the case (white thing with the LCD screen).
More specifically:
notice that the airport antenna (follow from the Airport card) disappears under the mother board near the lower left corner (face down);
just below the airport card is where the bluetooth card goes - plugs in w/connector and two screws.
remove the power supply;
remove the optical drive;
remove the hard drive;
disconnect the LCD panel connector - 2 screws;
disconnect two connectors on the left side (as you are looking at the thing face down) - one is under the optical drive, and the other you have to follow the cable you just disconnected down under a slender grey plastic component (Airport antenna part?) Take that component out too - 1 screw;
remove three screws across the top, just below the top edge of the case (white thing);
remove three more screws - one at each bottom corner (face down) and one mid way up the left side (these screws have coarse wood threads vs machine threads);
tilt up the metal frame with the mother board attached and lift it out.
the bluetooth antenna goes through a small "hole" in the sheet metal and then follows a bundle of black and brown wires to the right (face down) - there are 3 or 4 "tabs" made out of the sheet metal;
there is a distinct bend in the metal frame where a plastic bracket is glued in place and holds the end of the antenna, which has a printed circuit board about 1" long by 1/8" x 1/8".
It was relatively easy.

How To Install 10.5 On A 1st Gen iMac G5

Hi All
1:40am and I give up and ask for help!
I am trying to install 10.5 on my old iMac G5 but am having massive problems.
I wont bore you all with the history but just descibe the position I now find myslef in and hope someone can help me get this machine up and running.
So, now I know that my machine can't read dual layer disks and that I have to use target mode to my brand new MBP running the latest version of 10.5.
The iMac (please don't ask why) now has a formatted HD with nothing on it.
It will boot into 10.4 on the install DVD OK but I can not find out how to link the two machines and thus use the DVD drive on the MBP to do the install.
I have tried turning the iMac on with the 10.4 DVD in the slot and holding down T but that has no effect ... just boots into the 10.4 installation routine.
I have looked around in the 10.4 Utilities menu to try and find n option to boot into target disk mode but can not see it in startup disk or disk repair. Might be too late at night but ...
Any help with this gratefully received.
Thanks
David

Unless there's something wrong with your hardware the machine should be able to read dual layer disks, but the target mode should work for installation as well.
To boot off the leopard DVD on the iMac, press and hold "C" at bootup with the DVD in the drive, not "T". If this doesnt work (as you mentioned the thing has a hard time reading dual layer DVDs), then do the following to boot off of the DVD in Target Disk mode with the DVD in your MacBook Pro.
With the DVD in the drive, boot the MacBook and hold "T" and it will have the firewire symbol dancing on the screen. Connect the MBP to your iMac using a firewire cable. Then boot up the iMac and hold "options" down until it displays a list of drives that can be booted from. The Leopard DVD in the MacBook should be displayed (so should your MBP hard drive, but dont boot off of this). Select the installer DVD and press go (might be a bit laggy, so be patient), and it should boot into the installer.
