Pre-Intel Imac G5 17" Will not boot past safe mode, tried everything!

I have a 17" Imac with leopard that has been working fine until just recently stopped booting in anything other than safe mode. It will load the apple screen fine, then a ghost mouse image appears in the top left corner, which then appears, and sticks like you can move it. The blue screen appears and you now have your normal mouse that you can move around with the other one still froze in place, then the blue screen turns dark blue, then black and thats it. Your left with the mouse and a black screen and nothing else. I have tried resetting the ram, the hard drive checker command, apple, F O commands, single user mode, I checked the LEDS on the back the first one is always on, the second comes right on and the third lights when its supposed to. I did a complete erase and install of leopard and when the computer booted up you saw the the ghost arrow, and the same thing, but I waited awhile and you could hear the "Welcome to Leopard" music playing in the background It just doesn't make sense why the computer is not booting. Any advice is appreciated. I have tried it all. I am an apple lover, but this is one time where I am honestly about to throw it to the road.

Welcome to Discussions - from what I have seen, this could be your capacitors on your logic board about to fail, I'm afraid the cure would be a new logic bard. If you can take the back off and check to see whether the tops of the caps are bulging, that would be a definitive clue.

Hi All, Mac Pro 2008 will not start after shutdown straight from sleep! Help!

WILL A NEW LOGIC BOARD SOLVE MY PROBLEM?
My early 2008 Mac Pro (2.8, 8-core 22 gigs ram) was shutting down from sleep both when I activated it, and then later by itself. Recently it refused to turn on, shuts down after about 3 seconds, light goes off, fans stop.
Took it in and they replaced the GPU card and PSU. Things were great ... for two weeks. Then suddenly the same symptoms, but at an accelerated rate of occurance. After a day, it did not power on at all save the three seconds of startup fans.
Took it in again. They AGAIN replace the known-faulty ATI Radeon HD2600 XT cards (two), the ones Apple have agreed to replace up to July 2011.
Well got the machine back and she worked like a charm... for two weeks. Same thing now. By the way all checks of hardware, ram, disk drives - extensively have come up OK.
Does anyone have any advice, or have the same problem?
If it is the logic board, is it worth it to replace or when things go south like this is it better to cut your losses as more and more will likely go wrong?
Would appreciate any feedback.
Many thanks

We can't help with your question. How would we know what has gone wrong with your hardware? We don't have access to your machine.
I would take it back, or send it in, to Apple Repair.
I hope you have AppleCare!

My IMac 24" intel will not start in safe mode.

Did a Shift - Command-V and the black screen showing all the startup steps appeared and it all looked good except: AFL Alart Sockwed cant update and INIT Reboot transmit failed. All else looks good. I have tried this 3 times and never go past that point. Then the screen turns off white like it does when it starts normally before the apple appears and the last time the screen went black.
I have tried starting with just the Shift Key and computer starts up but not in safe mode.
I have tired starting with the OS X disk and the C key and it will not recognize the disk.I used the #1 disk since the instructions are printed on the disk. Did not work so I tried disk 2 and I get a menu to start the OS or tools. If I click on either one the screen goes white and stays that way.
computer starts fine and provides a login window, and then the desktop screen with screen saver pictures in perfect color. As it goes through starting programs it starts the same programs that is had open when the computer originally crashed. Even when I close them, before it locks up again, and I am forced to restart the same programs open up to the same place. Its like the computer is frozen in one location and will not go beyond that point. Eventually the screen turns white and sometimes black and sometimes gray.
Tech support thought it was the video card, put a new one in but did not fix the problem and then said it was not that but that it was the monitor. I said that did not make sense since the monitor and desktop icons and pictures are beautiful and clear. They then said it was the inverter board on the monitor and Apple only replace the whole thing. I purchased an inverter board and replace it. No change. The tech person said that the computer works find without the monitor connected - I will see if that is correct next. Isn't that a more systimatic testing procedure then trying parts to see if it works? Oh I did do the complete long hardware test. Took about an hour and it passed! Isn't this strange?
I have to replace a monitor that has perfect color and image if it is something simple to fix or replace. Has anyone ever encounter anything like this? Could it be a virus?

As you probably read everthing was working fine for over an hour so I shut down and put everything back together completely, all monitor screws, aluminum cover and screws and screen cover, unplugged the external monoitor, plugged in external HD's and turned on the computer and guess what the old problem returned. So I unplugged the external HD's and plugged in the external monitor and took the screen cover off and restarted the computer and guess what it is working fine. Doing a disk utility verify first then if no problem I will unplug the external monitor if all is good then I will plug in the external HD's if all is good I will install what I believe is the problem the monitor cover screen.
Your post about the Temp sensor and another post about the cable to the monitor with the temp sensor has me believing that the monitor is getting too hot for the fans to cool down or the sensor is faulty. Which one is the temp sensor? It is the monitor cable that has the little box at the end that screws to the logic board?
How do you know if the secsor is bad or the monitor is overheating and the sencor is working correctly? Is there a test?

this is a brand new system from zt systems. it came with almost no software installed. no toolbars or anything, only trial of microsoft office.

MacBook Pro 13 2010 running Mountain Lion: will not boot and shows a folder with a flashing question mark. Will not start in 'safe mode' i.e holding shift on start up - nor can I call up any utilities with the OSX shortcuts. Any thoughts?

Following an automatic update, the machine wouldn't boot. Screen came on (shows white) - then either showed a 'No-Entry' Sign and a spinning cog, or a folder with a qusetion mark. I tried to start the machine in different modes ( eg. holding shift after the tone ) but nothing worked. after leaving the machine alone for 1 hour. It worked perfectly again. I did a 'verify disk' check which found no problems. 2 hours later it then froze ( In - Photoshop). Could not force quit, so shut down, and have not been able to boot again since (white lit screen - flashing folder with question mark) . I have also taken the hard drive out and checked the connections which seem fine. Any suggestions? - Is the Hard Drive dead. : other info : It was also running parallels 8, with Windows 7. at the time of the update....

This article may help: A flashing question mark appears when you start your Mac.

Will not start in safe mode

Using PB G4 15 in. Trackpad froze and then machine auto shut down. Restart failed. V boot failed. Pram boots all failed. Has reached apple screen once but froze and auto shut down again. Please help.
Ps note sure which OS as can't power up to check. Was fully updated

can you be a little clearer in what you have done so far?
by v boot, do you mean booting to Verbose mode? and PRAM boots - the system shouldn't boot when you reset the pram, it will clear the contents of the PRAM and reboot back to the chime when finished.
sounds like it could be a hardware problem - maybe a hard disk problem. Apple recommend booting from a disk first and using Disk Utility to repair the disk. If you can't do this try booting to single-user mode (hold down cmd-s on start up) and use the command 'fsck -fy' and then issue 'reboot'.
If that doesn't work try booting from an external disk or mac through traget disk mode, if possible. if not, take the machine to the nearest service centre.

My Mac Pro 2.8 crashed and will not reboot in Safe Mode - HELP!

Hello
I have a Mac Pro 2.8 and it froze up on me; I held in the power button to shut it down. Upon restart, all I get is a flashing foldoer file icon with a question mark.
What gives? It will not start in Safe Mode, via the Shift button OR DOS command (sudo nvram boot-args="-x")
1. How do I get it back up? I have a back up on my external hard drive, but it doesn't recognize it?
2. Are all my current files gone?
Thanks for your help

A flashing question mark on boot can mean several things. One, your Mac can't find a system folder to boot from or the startup disk is failing or failed.
Since you don't have the install discs now, it may take some time to order and receive them from Apple. Probably time to take the Mac to an Apple Store or Apple certified repair shop. They can tell you for certain whether or not the disk has failed.
Since holding down the Option key that prompts the Startup Manager window didn't work, not does your external drive recognized your Mac, I'm afraid without a backup to restore those files from, you may be out of luck.
can I get a new one from mac, and will it erase all my files?
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

2009 Mac Pro Quad Will Not Boot

Hi.
I have a 2009 Quad 3.0Ghz Mac Pro that will not boot up.
I went to it this morning and the beach ball was spinning. I could not get it to stop and as a last resort, turned it off. It has been working fine, although
I have noticed a little slow (Could be me, though).
When I tried to reboot it, it tried to start, chime went off, but it stayed on the light grey screen and eventually, it had a folder with a question mark in it
that blinked.
I disconnected all peripherals, no change.
Tried to boot from the optical drive with Disk Warrior, no change.
Anybody have any ideas?
Thanks in advance for any help.
Brian

The Chime is generated in Software when the first part of the Power-On Self Test has passed. If an appropriate source of software can be found, booting is likely.
it had a folder with a question mark in it that blinked.
That says it could not find the last-specified source of software. the drive may be damaged, or it may have forgotten where it should be looking.
Tried to boot from the optical drive with Disk Warrior, no change.
Next try a 10.6 DVD. "A Mac that cannot boot from an appropriate Installer/Utilities DVD has a Hardware problem".
One of the simplest things it should be able to do is Startup Manager. Hold down the Alt/Option key at startup and it should draw a gray or blue screen and slowly draw an Icon for each potentially-bootbale device (including a bootable DVD, if inserted).

Need to erase hard drive and reinstall system on iMac but have misplaced original install disks. Tried to use a my copy of Snow lepord 10.6 from my Mac pro but will not boot. Can original install disks be replaced. Thanks

Yes the original Install Discs can be replaced for a nominal fee. Call AppleCare, you will need a credit card and the serial number of the machine. You can use the AppleCare Contact Info for the phone number on your part of the planet.

Firefox crashes when opening and will not open in safe mode

Recently FF3 started crashing when opening. It will not open in safe mode as well. I have uninstalled it including deleting the install folder and profile folders as well as registry entries. Upon reinstallation is will still not launch in any mode.
I have scanned for malware with several scanners and that has not found anything.

I have no navigation bar and firefox will not open in safe mode to reset to default config. Reinstalling doesn't work. Any help please.

I have no navigation bar ever since I closed it to gain more space on the screen. It won't re-open. Firefox will not open in safe mode, but opens immediately in normal mode with the new improper config, so I cannot reset to default config. I erased Firefox and re-installed and it still opens with the same faulty config. Why does Firefox not give me the safe mode dialog box, why can I not re-open the nav bar, and how can I do these two things, please? Firefox is currently unusable for me without a nav bar and without access to the default settings in safe mode. I cannot research the extensions I'm running since I have no nav bar to go to Tools, Add-ons, Extensions.
