Ibook boots to a point then stops....

HI,
I got a ibook g4.
Recently i boot it up and notice it starts up very slowly. It reach to the point of loading the main screens but software I launch it just hangs there.
2 days ago, there was a loud fan sound when i start up the mac.
Could this be a hardware failure on either:
1. logic board
2. Harddisk
or the mac os X is corrupted?
Appreciate if someone can advise me.
Thanks

Welcome to Apple Discussions.
Try starting up in Safe Mode. When computer is booted log in, empty Trash then restart.
If the problem persists run:
Repair Disk
Insert Installer disk and Restart, holding down the "C" key.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
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.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
I don't think your problem is hardware related. However, if you think it might be boot from the Apple Hardware Test disk and run the test. If you suspect Hard Disk Drive failure go to Applications > Utilities > Disk Utility. Select your HDD (manufacturer ID). At the bottom of the main panel notice the S.M.A.R.T Status. If it says Verified you are fine. If it says Failing, backup up your HDD immediately and get a new HDD.
Good luck.

P55-GD65 boots for 1 second then stops

My P55-GD65 worked lovely for over 2 years but now suddenly it does the following:
It boots for 1sec and then stops. During the boot led6 (of the CPU phases) flashes on and the fans start spinning. This process repeats itself every 3 seconds.
I did the following:
checked the PSU by disconnecting the 24pin molex, shorting pins 15 and 16, and verifying all voltages.
Disconnected the supply to all devices, except for the mobo, still the 1second boot behavior.
Removed the 4 memory strips and placed only 1 in the 1st black bank
Maybe worth nothing is that I never switch my comp off, but keep it in standby. Does this wear out some parts?
Somebody an idea what this could be? Or how to debug this?

I did:
--clear cmos
--took another memory strip
--took another but old power supply with 20pins molex
--removed video card
all did not change the 1second boot behavior.
I fear I have to give up the mobo. Is repair a viable way to go?
No, probably best to replace the mainboard. If you buy the board from a computer shop, see if they will test the cpu and PSU for you if you buy the mainboard. Just to make sure.

OS X Won't completely boot - blue screen, pointer then nothing

(MBP with problem is 2.0GHz Core Duo 15" MBP. 1.5GB RAM)
As topic says, g/f woke her MBP pro up from sleeping to type an email. Shortly after opening the mac everything stopped responding. She held down the power button to turn off the mac and then turned it back on. MBP loads past grey Apple screen and shows the progress bar for loading OS X. Once progress bar dissapears then nothing, just a blue screen with the mouse pointer.
I have already done the following:
- Booted from Install DVD and ran disk utility. Verified Drive but no isssues. Verified and Repaired Permissions. Still didn't boot
- Booted in 'Safe' boot. Exact same problem
- Booted into Single User Mode and ran fsck -fy, no problems reported. I can browse the drive and see files etc.
- When I attempted to finish loading OS X from the command line I do remember seeing the following error: coreservicesd crashed. Googled but couldn't really find out anything I understood to help.
What are my options here. The MBP in question is unfortunately about 2 weeks past the Warranty date w/ no applecare but she may take in tomorrow regardless.
Can I use a firewire cable to connect the two macs and at least get the most important data off if we have to reinstall?
Thanks in advance for the help!

That sounds like wake from Hibernation/Deep Sleep - there's no "progress bar" with a normal Boot, only a spinning grey wheel then the Desktop appears .
I believe this is the screen he is referring to.

Imac boots to apple screen then stops?

Imac running osx Lion boots only to apple screen. I have tried boot discs and flash drive to boot it with no luck. HELP

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
Step 8
A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Videos from any source on any browser buffers then stops.

Every time I watch a video, whether it be from Youtube, Facebook, Google, etc. the video would load up to a certain point, then stop buffering. This affects all browsers such as Chrome, IE, etc. The problem is NOT my Internet connection, because I can load other pages even if the video freezes. Also, if I'm desperate enough to want to watch the rest of the video, I have to skip just a little past where it stopped buffering and it would continue, only to stop buffering at a later point. I have tried:
Pausing... video would stop buffering at the same point as it would if I didn't pause the video.
Clearing my cache
Uninstalling and Reinstalling Flash
Uninstalling and Reinstalling browsers
Other notes: This problem was recent, starting about last week. Also, loading videos at a lower resolution/shorter videos stop buffering much later than loading videos in HD or longer videos.

Hi, thank you for your prompty response, I discovered the issue is due the equalizer, it was set to high levels so the recorded sound was distortioned. So it is just needed to set the equalizer to porper levels and that is it.

What is the error? Are you following the Bootcamp instructions? Where on the "internet" are you trying to install from? Did you try downloading from here http://www.apple.com/support/bootcamp/downloads/?

680 TF fan spins at boot then stops

MSI N680GTX Twin Frozr 2GD5/OC GeForce GTX 680 2GB
I have two of these cards in my rig. On one of them at boot time, one of the fan spins a second then stops and does not spin again. What could be the problem?
I removed and inspected the card, in fact, both of them. The card and the heatsink are clean. I rid the inside of then case with a blower every two weeks. The fans spin freely, so I don't think the bearings/bushings are stuck. I re-seated the power cables and the 4-pin fan wires. So. I don't think the problem is power is not reaching the fans. But no joy.
What stumps me is the fan spins momentarily then quits.
Has anyone had this problem before?
Any opinion on what the problem may be is welcome.

IBook Boot Failure

Today I restarted my iBook (G4 early 2004) and upon powering up, the gray loading page came up for about 5 minutes (it's never been this long before). After the gray screen, the screen became blue like the background for the login prompt and again a ring to indicate loading appeared for about 5 more minutes. Then the cursor appeared on the blue backround and the computer stopped spinning the hard drive and nothing happened. It refused to boot completely, but because it showed the apple symbol at start instead of the missing file symbol, it's shouldnt be hard drive problems (and the HDD sound fine).
I've tried:
Safemode
PRAM reset
PMU reset
Removing the battery for and hour
Booting off the original OS X install cd that came with the iBook
All of these failed. And on the case of the OS disk, the iBook swallowed it normally while booting but did not acknowledge the disk while restarting. The disk did not even show up on the list when I held option down while booting. The disk then refused to eject even though I held the mouse button down while restarting.
The computer has not suffered from any physical damage recently (and by recently, I mean It's been serving me on my desk for the past 5 months without any need to actually move the whole laptop). The only out of ordinary thing that I did was setup SSH on the computer (succesfully) the day before.
Oh yeah, and the reason I restarted the iBook (5 sec on the power button) before this problem was that the whole system became non responsive while trying to shut down normally.
In other words, I'm stumped.
Any ideas about whats wrong?
Thanks, Santeri Raisanen.

Hi sraisanen,
Well can you get it into target mode?
http://docs.info.apple.com/article.html?artnum=58583
You could run Disc Warrior and see if it can be repaired.
If not see if Data Rescue II can salvage the data.
Well, turns out i was wrong the whole while. I managed to get a hold of my friends copy of OS X (i guess mine was scratched)
I have 5 backups of all my installers
and I managed to boot of that.
Yes I use a standard DVD player, Apple branded, out of an old B&W G3 in an external FireWire drive. That way I know the ins and outs of that drive and I'm not dependent on the vagaries internal.
I ran the disk utility and got a nice little of list of errors on my boot partition. The strange thing is that instead of the 'boot folder not found' symbol, it continued to boot when attempted and stalled at a blue screen.
Yah kinda depends on how it's messed up.
Disk utility didn't manage to solve it, so i guess im gonna have to somehow back up the data and reinstal
Yes and I'd be wary of that drive it might be on it's way out. I run SMART Reporter on all my machines.

HP PRO 3400 Series desktop won't boot CPU fan starts and stops , no video, no beeps

I have the above computer with an i3-2125 CPU, Windows 7 Home Premium 64 bit, and a 300GB Seagate Hard drive. I've had it for about 2 years and been working fine. It started acting up about 2 months ago. It would lose the date and time. I checked the battery, and it was OK, so I kept using the computer. Then on 9/15/2014 it hung on "Starting Windows", I did the following:
1. Ran the built in HP diagnostic on hard drive and memory and they both passed.
2. Tried to go to last known good configuration and nothing happened.
3. Noticed the date and time were off, replaced the battery, nothing changed.
4. Tried another hard drive from another HP PRO 3400 Series and it would boot up but could not set date in bios.
5. Tried all kinds of things but could not set date in bios.
      a. Bios date read 48/00/0048 after removing and replacing battery.
      b, Tried to reset date to 9/16/2914 and it gets 56/00/0051
6. Then it wouldn't boot at all.   So now when you turn on the power, the CPU fan starts and runs for about 1 second, then shuts off for 4 seconds, then starts and runs for another 1 sec and it does this continuously. There is  no video and no beeps and no difference when all memory is removed.
7. I removed the power supply, and checked voltages. It appears to be OK.
8. I removed the motherboard, and inspected it- saw nothing obvious.
9. I connected the power supply to the motherboard with nothing else connected to the motherboard, and I get the same thing. CPU fan starts then stops continuously, no video no beeps.
10. I am thinking it is the Motherboard, but I sure could use some suggestions as to what to do next.
Thanks

Emac tried to start then stopped, finally after 3 attempts it started

After a hard drive failure i run my emac on an external hard drive through a fire wire.
That worked OK till yesterday when it tried to start but after a few seconds of the normal fan noise and before the screen lit up, it stopped. I hit the switch again and it did the same thing 3 times but on the 4th attempt it started but a white screen came on and told me to type "mac-boot" and hit return.
It finally started.
The external hard drive was still running OK at the time it had stopped, it was internally that it had stopped.
I took the back off the emac and vacuumed the dust from inside and after that it has since started normally every time though it seems slower to start, but I could be mistaken about that as I can't now remember noticing how long it took to start before.
Someone said the problem could be the power supply failing.
Is there any way for me to diagnose what exactly is wrong, since an emac power supply is not same as a PC power supply?
Could a PC power supply be modified to replace the emac power supply as I have a failed PC with a good power supply I could use if it would work?
Any help or suggestions would be appreciated.

Hello and thanks for your reply.
I neglected to mention that at the time of the hard disk failure I put a new hard disk inside too with the intention of using it as a back up to the External Hard Drive but I found it was easier in the end to get another external hard drive and now I use Time Machine to back up on to that 2nd external hard drive every few days.
I disconnect the 2nd external hard drive when I'm not backing up data on to it.
Most of the time when I boot up the emac it somehow knows to go straight to the 1st External Hard Drive instead of the Internal Hard Drive but occasionally it will go to the Internal Hard Drive and when it does that I have to go to System Preferences and then to Startup Disk and actually select the External Hard Drive icon and that's what I had to do every time when it was having that weird starting then stopping phase, ie, every time during the starting then stopping phase, when it did start it went to the Internal Hard Drive even after I would go into Startup Disk and select External Hard Drive it would start on the Internal Hard Drive, so in the end I didn't bother trying any more and I just connected to the internet through the Internal Hard Drive until I took the back off and vacuumed the dust out and ever since I did that it's been running normally, ie, it's always selecting the External Hard Drive again and running at what seems to be normal speed for everything too.
I just don't know why it went into that starting then stopping phase.
When it was in the starting then stopping phase the internal fan noise would stop but the little white light next to the DVD door would stay lit up so it was definitely getting some power from somewhere but it was failing to go on and boot up because the power to the internal fan had failed ie, I could clearly hear the fan stop only 3 or 4 seconds after hitting the start button.
I've just had a look at the capacitors that you suggested and they look perfect, like new in fact, they have a shiny metallic top with a + indented in the top and they are flat and they show no sign of a dried up liquid or any bubbling up anywhere.
Anyway, your reply was helpful since you ruled out the Power Supply and the capacitors, so thank you for those.
The friend who advised me how to get going again after the initial hard disk failure, ie, via the External Hard Drive connected by fire wire, did warn me not to touch anything in the back that wasn't directly related to changing the hard drive but thanks for the heads up anyway.

When playing my i-tunes library through my hi-fi via Airport Express, how can I get i-tunes to play a single album and then stop, without continuing on through my entire library. It's a problem that doesn't occur when I'm listening through my i-pod.

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

Time machine is not backing up - starts to, then stops. No error.

Time machine has stopped backing up. I have plenty of space on the external drive. When starting a backup, whether automatically or manually, the process will begin, and may even get to the backing up stage, then stop. No error message, but no backup either. This has been going on for 12 days, and I hadn't noticed as the icon at the top of the screen was not showing a backup issue.
I have checked and repaired permissions, and the external disk. There were a few issues, but they have been corrected. Still no luck.

Okay,
I ran the widget, and here are the results. The backup never got to actually backing up, it got stuck on "cleaning up". After 5 minutes, I hit stop backup up, and it was stuck on that till I restarted.

Multicast works for a day and then stops

I'm running multicast in unicast mode on our WLC because I can't enable PIM on wired side yet for a couple reasons. It works consistently on 3 out of 6 WLAN's. And the weird thing is the other 3 WLAN's will work for a day, and when I come in the next day, multicast traffic has stopped flowing. I have verified this through IGMP snooping, using a bonjour browser, testing airplay, and using packet capture on a wireless NIC. 2 of the WLAN's are configured almost identically, but one works consistently day after day, and the other only works for a day after resetting the wlan. I have been coming in the morning and changing a single setting back and forth just to reset the WLAN so it will work for the rest of the day. I'm just writing this to see if someone can think of why it would work fine for the shole day and then stop working by the next morning. It's not an IGMP timeout setting, because it works for much longer than the timeout and behaves the same way even without IGMP snooping on. It started doing this after upgrading to 7.0.240.0. We have very little amount of multicast traffic on wireless, and low channel utilization. It does the same exact thing whether 802.11a or 802.11g so I don't think it has to do with data rates. When I have IGMP snooping on, and on the WLAN's where it's not working, the controller will see the multicast group join message from the client, but the client doesn't see the IGMP query from the controller. It shouldn't be wired config related since it's unicast mode. I've tried with and without broadcasting enabled. Any ideas?

Okay, so I discovered two things, but I still don't know what caused this problem. When I was running 7.0.230.0 I had increased my EAP-Broadcast key interval to 86400 due to a bug. This seems to be related to the fact that on the wlan's where multicast was not working, it stopped by the next day. When I backed this interval down to 3600 the multicast stopped working after an hour instead of a day. So that's why I believe it was somewhat related to the broadcast key, since that key is used for multicast.
What I realized is that multicast was working on all the wlan's on all AP's that had been rebooted since the controller upgrade (They had been rebooted due to a switch losing power). This is weird because all the AP's were rebooted when they received their own 7.0.240.0 software upgrade, so I don't know why they would have needed to be rebooted again. Anyway, I rebooted a few more AP's and multicast works properly on all wlan's on those. I'm just replying to my own thread here in case someone has a similar problem after upgrading your controller - try rebooting all your access points again. Or maybe reboot after changing EAP-Broadcast Key interval.

Hi Guys:-
If this SAME problems is effecting us all then suspect its not IPS problem as we all get problem at 995.6MB.
I would think that there is some kind of software conflict. If we all having this problem just think of how many users have the same but are not on this discussion board, bet you its 100s and 100s.
Not possible for me to visit store now but will monitor your responce's.
Good luck guys, lets make um give us a fix:- I will call them tomorrow and see what they say:- should point support to this Discussion page and they can answer us !
Cheers and good luck also
