No Video - Ran Diagnostics everything passed - reset PRAM, NVRAM etc.
Hello,
My cousin's Power Mac G5 Dual 2.0 out of a sudden does not boot any more.
You just see the apple logo and that is it.
When I turn it on, you hear the booting chime sound and the fans spin, no LED activity at all.
I tried reseting the PRAM, NVRAM that did not do much.
I ran the diagnostics CD and that passed all the test successfully logic board, mass storage, memory, and video ram. Airport I don't have and the network cable was unpluged.
I tried hiting the install new system icon when I booted in the diagnostic mode, I had to put a paper clip in there for the cdtray to open, and I only saw the same old mac logo.
What do you guys think it is. I was suspecting a mother board, video card, or memory, but all of those obviously passed the test and the video card worked.
What else could be wrong for the computer to not respond at all.
Thanks in advance,
Erion
Power Mac G5
Thanks for the quick answer first of all.
Yeah, it does not boot at all by itself.
I had to use a paper clip and manually open the CD tray to put in Disk One which includes the Diagnostics software. I restarted the computer and held "Option" a couple options showed up
- Boot from hardive
- Install the OS
- Run diagnnostics
The first couple result to the same final stage - a gray scree n with the mac logo in the center.
I ran diagnostics a couple times, both quick and advanced modes and it passed them all:
Logic Board - Passed
Mass Storage - Passed
Memory - Passed
Video Ram - Passed
I just burned a copy of Ubuntu's PPC version so will try if it boots from it. If it did that will tell me that the Memory is really ok or not.
It is not a Power supply problem because obviously it ran the diagnostics CD. It is also not a video card because I saw displays in the diagnostics mode.
No idea what this is and I am kind of hesitant going and spending money in the dark. If the Live Ubuntu CD boots, than I will probably buy a Serial ATA hardrive to se if that will work, or better I should make it some sort of external so that I can use it even if this does not succeed.

Have iPod Nano Shuffle 6th Gen. I purchased it when I had Windows Vista. I have since upgraded to Windows 7 Ultimate . Was fine with Vista. Now, it keeps shutting off during the song, 3 or 4 times. Have to press power button and then arrow to restart song. I went to my iTunes and ran diagnostics. Passed all until the end. The last test had a red dot failure. It said no iPod, iPhone, or iPad found. Does someone know how I can correct the problem? iTunes is always updating, so I am current.

Firewire 800 failure resetting pram &nvram did not fix.
Help with fixing my firewire800 on imac 27". resetting pram &nvram did not fix. what else can i do ?
Slower doing what?
You have an older Mac that really wasn't built to run Lion as fast as it ran older versions of OS X. Although it will run Lion, Lion will be slower even with a RAM upgrade. You did not upgrade the CPU to a faster model, which you CAN'T, and Lion uses more resources then older OS X versions like Snow Leopard.
So you have 2 options.
1) Stick with Lion and accept the slower computer.
2) Wipe the drive and reinstall Snow Leopard and then use your time machine backup to load all you program and files back on the system. -
Reset pram & nvram now my imac is slow.
Hello,
I decided to reset my pram because the disk startup preference pane wont recognise my windows drive but i could boot into windows from my firmware. I read on the internet that resetting the pram might fix it.
After i reset my pram my computer took a long time to boot. then it came up with a folder with a " ? " in it. so i booted from my os 10.6 install disk and ran the disk utility thinking my harddrive might be faulty. it didn't find any errors. When it booted it also made the bong sound but at max volume.
I left it for a while and it eventually booted into osx but every time i typed in a letter it would lockup with a beach ball for 5 mins. ounce i logged in and my computer was running for a while it started to run close the normal speed.
I was wondering if there was a way to restore/reinstall the firmware?
could someone please explain to me in layman's terms what resetting the pram & nvram actually does?
i hope im not missing any details. Im looking forward to getting finding a solution. Thanks in advance.Thanks for your help.
I my internal harddrive as the boot drive but it booted of my backup drive.
It doesn't seem like anything is being written to my firmware. I muter the volume but the startup sound was still at max.
When i booted back to the internal harddrive it had the same problem. The problem doesnt occur on the external drive. so it might be my harddrive. Do you know any good tools for checking my harddrive?
but the problem only started when i reset my pram. -
The tiger install dvd boots only to show an image of what looks to be two steps, not sure what its showing me.. possibly inserting RAM? Anyone have any ideas? Thanks in advance.
Could you get a picture of the screen, load that into your working computer,
and post it into a reply here? There are a few kinds of situations where a
similiar display of that sort may appear.
Given the G4 iBook PPC (which model) is a bit dated now, one has to
assume you have the original 'install-restore' DVD it came with, new.
What was or wasn't it doing, before you chose to try to boot Tiger DVD?
Do you have a second Mac, one w/ FireWire ports; maybe Thunderbolt?
It may be possible to further look into the ailing iBook G4 via FireWire
from a second Mac, and attempt to investigate, or save old data to some
external drive, USB Flash; in case you need to totally wipe the HDD.
An image of the iBook screen may be helpful. Someone else with recent
troubleshooting or extensive use of iBook portables (or other OS X issue)
that presents such a screen instead of a normal progress screen, may
have an immediate idea. Without an image, I am not venturing a guess.
What key did you hold down while trying to boot the computer from DVD?
One set of keys can get you a Startup Manager. Among other options. -
I am trying to update the new OS system on my iPhone 4, however, when I connect to iTunes and try to download, I keep getting an error message that says the connection is not established. I ran a diagnostics test and everything passed, however, I'm not sure why I keep getting an error message when the software is at the end of downloading.
Any tips?Disable your firewall/security software.

We have had several (7-10 recently) macbook Pros start this issue. The screen will jump from regular to blue, the background image will go away and it will be replaced with a blue screen, the icons change size and the screen resolution changes. Someimtes the users name field on the login screen will fly in from off screen... run diagnostics (AppleJack, Disk Util) and reset PRAM and SMC and sometimes this helps but wanted to know if there was a definite reason for this or a better resolution to the problem?
Thanks all
Macbook Pros are all newer (some only a month old) Unibody models running Snow Leopard and LionAppleJack has been discontinued, so you should uninstall that.
I'm suspecting something in software across all machine or a security breach as the primary cause of your problems.
Wipe and install everything fresh, firmware update the router, change passwords, new software form original sources, etc.
This might assist.

No Video, Can't Reset PRAM, boot sound/led light/fans all okay - logic brd?
Hello All,
I'm trying to find out what's wrong with my G5 Tower. When I push the power button on, the led lights up as usual. The fans spin, hard drives/optical drives spin, everything appears normal. However, I get no video. I've tried reseating the video card, disconnecting power for 10 mins, and reseting the pmu on the logicboard.
I believe the problem is either the logicboard or the video card. I tried resetting the PRAM multiple times, but it doesn't work. It's as if I'm not holding down the buttons on the keyboard, or the keyboard is not responding. I've tried a couple different keyboards.
Does this seem like a logicboard thing since I can't reset the PRAM?
Any help or suggestions very welcome!
Thanks!Hello Again! Check the voltage of the battery to see if it's 3.6 volts. A weak battery can keep it from starting. I have seen video cards go bad. Have you tried an alternate (if one) slot for the video card? Tom

Thank you for using Apple Support Communities
First I recommend taking a look at this article named iTunes: Music purchased from iTunes Store cannot be burned to MP3 format CD found http://support.apple.com/kb/TS1476.
Songs purchased from the iTunes Store may either be in AAC format or AAC Protected format depending on when they were purchased (older songs used AAC Protected format). You can convert AAC songs to MP3 format allowing them to be burned to an MP3 format CD, however AAC Protected songs can not be converted. You can, however, back them up to a data CD or DVD, or you can burn them to an audio CD (which can be played in a CD player).
And if your issue still persists after converting any of these purchases, then I would recommend this part of the article named Disc Burning Quick Assist found here http://support.apple.com/kb/HT1152#learn2:
Top troubleshooting tips
In addition to the following tips, check out these articles:
Solving problems with burning discs
If the disc burning options are dimmed or unavailable
If a burn does not succeed, check the disc or try another disc
Eject the disc from the drive and inspect it to see if the surface is dirty or scratched, or if it already has data written on it (the shiny surface is slightly darker where data has already been burned). If it's dirty, wipe it clean with a soft, damp cloth and try burning again. If the disc already contains data, try another disc. If you're using a rewritable disc that already contains data, be sure to erase it before burning data on it again. Small flaws or surface inconsistencies can cause an unsuccessful burn. Try burning your content to another disc or try a different brand of disc (if possible).
Make sure that your optical drive can record discs
If your drive is built into your Mac, make sure that you have at least a Combo Drive if you want to burn a CD or a SuperDrive if you're trying to burn a DVD (or CD). Consult your Mac manual or your third-party manufacturer's disc drive manual for more information.
Check the disc type
Make sure that your disc drive is capable of writing to your media at hand. For example, you won't be able to burn a DVD+RW disc with an older Apple SuperDrive. Consult your Apple or third-party product manual for your drive's supported media specifications. You should also use discs that are rated for the burn speed of your drive.
Slow things down
In the Burn dialog, specify a burn speed that is slower than the maximum speed rating for your disc drive (if you can) and try burning another disc.
Free up some memory
If you've got other applications open, quit the ones that you're not using (or quit them all except for the one from which you're burning your disc). Allow the disc to burn before doing other things on your computer.
Check your hard drive's available space
When you burn a disc, your Mac temporarily sets aside an amount of hard disk space equal to the amount of data being burned to the disc. If you're burning a large amount of data, you may run out of room on your hard disk if it's almost full, which may prevent a disc from burning. To free up space, throw out unwanted files or back up files to an external drive.
Restart your computer
Sometimes a simple restart can resolve issues. Once you've restarted your Mac, try burning another disc again.
Update your software
Use Software Update (from the Apple menu, choose Software Update) to check for, download, and install the latest versions of your Apple software. If you're using a third-party burner, visit the manufacturer's website for the latest software updates for your model.
Check your connections
If you're using an external disc writer, make sure that all of your cable connections are secure and that the optical drive is powered on.

My MBP A1226 display went black n no video output. I tried to reset pram n a hard reset still nothing. It boots up drive and volume beeps like its running... It's running but no video. I'm out of warranty, is there something I can do without spending a fortune. Thnx rich
Hi, I have the same computer, same model and same problem with the same diagnosis, with no response from Apple for being out of warranty of 4 years, this is a shame!
-
Here's what I've tried;
SMC reset
Pram reset
Looked at activity monitor - mostly seems OK aside from a kernel task taking up memory (approx 460MB) but CPU is around 96% idle.
Fan seems to be running constantly - heats up noticeably when I close the MBP
Despite a re-install of Mavericks, MBP is running frustratingly slow. Just typing is enough to bring on the beach ball.
Have backed up everything, reinstalled from a clone, checked through Apple Hardware test and carried out a Verify Disk Permission - nothing was reported, erased the drive and set up again - problem still stands.
Memory is running at 3.43 GB without anything really running bar Safari.
A little loath to install SMC fan control without knowing what's wrong.
Checked software updates.
Can anyone tell me what the matter is? Does this have a fix?
Have been reading up various posts but to no avail so have resorted to posting myself.
Does this sound familiar to anyone?
Many, many thanks
Roque1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Booting Problems! Have to keep resetting PRAM
Hey everyone,
I just got an iMac education model. It was running sweet for a day, then ran all the updates etc and let it sleep for ages cos I had to go out.
When I tried to wake the computer it didn't work and subsequently I couldn't reboot it. I discovered through these forums that I had to reset the PRAM so did that and problem solved. Worked great, shutdown, went to bed.
Next evening I pushed the on button and same thing! Blank screen even though the computer was on, so I reset the PRAM again and it works fine now. So I ran update again, got one more security update, repaired permissions, did a boot from the OS X cd to repair the drive (didn't need repairing).
Question is - why would this keep happening? I'm hoping it won't happen again, could it just be faulty RAM? Does anyone have an intimate knowledge of PRAM?
Thanks alot!
Gareth
iMac (intel core duo) education Mac OS X (10.4.7)Hi Gareth, I am hoping someone will respond soon to your post.
I am experiencing very similar problems with my brand new iMac G5 iSight education model Intel Core Duo 20 ''. During digital audio sessions and i.e. running iTunes visualizer for 10 minutes, computer shuts down, will not restart until I unplug it for 10-15 seconds. I have reset PRAM, run permissions repair, hardware diagnostics (no problems), but hesitate to open the back cover and reset SMU (apparently our model has switch, can't be reset by rebooting if I understand correctly (see http://docs.info.apple.com/article.html?artnum=300908). I am concerned it is a power supply issue, but using the terminal app, it doesn't let me see the "kernel buffer", so I can't see if it is returning a "-110 error". There is an interesting discussion about consistent power supply 9http://discussions.apple.com/thread.jspa?messageID=2771605�) where an iMac owner couldn't repeat the problem at the Apple service center because they apparently had better power. So I am going to try putting a power conditioner (rather than just a surge protector) in place. If it is a software problem, this seems unlikely, since I have only been running the computer for a week and have a limited number of applications installed, but I will do an "archive and install" from the installer disk if this doesn't work. I hope I don't have to take it in for service. Any other ideas out there, anyone?
Thanks, Cody -
External Display resolution problem after resetting PRAM
Gello, I've got Fujitsu-Siemens P19-2 monitor hooked up to my MbookPro and after resetting PRAM the correct display resolution disappeared from the "Displays" menu in System PReferences.
So did the refresh rate option...
What do I do?
I really need to change the refresh rate and the resolution, but the refresh rate button is grey and unclickable, and the resolution simply isn't there (I need 1280x1024).
REsetting PRAM and SMC didn't help.After a couple of resets everything went back to normal

I keep getting an unknown error when trying to connect to the store. I ran diagnostics and it says secure link to itunes store failed. I've tried all suggestions from apple and nothing will work.
Please HelpI received this email from Apple and this corrected the problem for me... I only had to reset the iTunes cache
1) Open iTunes
2) At the top menu, click File > Preferences (iTunes > Preferences on a Mac)
3) In the Preferences menu, click the Advanced tab
4) In the Advanced menu, you should see a button that says "Reset Cache". Please click this button. -
I've been having two issues with my Late 2008 MacBook Pro 15-inch - Running OS X 10.8.5 (Mountain Lion). Unable to Reset the PRAM and Run Apple Hardware Test (AHT).
On a random basis - File/Folder icons are Sticking to the Mouse Pointer - Not Releasing. I've done everything from trashing finder preferences, making sure Universal Access preferences are off, Restoring Defaults in the Energy Saver System Preferences, Resetting the System SMC. Another post mentioned that this is being caused by the Graphics Driver not working correctly - and mentioned to put the MBP to sleep, then wake it up, and the files/folders are no longer sticking to the mouse pointer. This works for me and released the sticking items in the Finder.
OK, Good this is a simple fix, BUT, what is really causing this issue, and how may it be fixed or repaired?
I also tried to Reset the PRAM and Run the Apple Hardware test (AHT), and these both fail to run on my MacBook Pro with OS X 10.8.5.
1) Resetting the PRAM:
Shut down the MBP, press the power button, and hold down at the same time <option><command>-P-R. The Reset PRAM process never starts up, but rather I receive the Padlock/Password Login which logs me into the Restore System Utilities. I'm unable to Reset the PRAM.
2) Apple Hardware Test (AHT):
Shut down the MBP, press the power button, and hold down the "D" key, the system boots up as normal and does not enter the AHT.
The File/Folder Finder sticking to the mouse pointer issue is very annoying. Does anyone have a solution to resolve this issue?
- CheersHI Barbara,
It sounds like the hard drive is failing or has failed. Boot from your Mac install disc and if you can run Disk Utility in case the startup disk needs repairs.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
What is Safe Mode
