IMac not starting up in normal and safe mode

i have tried booting up mac with shift, c, option and cmd+opt+p+r keys, but nothing is working to boot the system properly, every time i switch it on it displays the safe mode bar (without even pressing shift key, i have tried it by disconnecting the keyboard) which loads till half and then turn off the system completely.
Please help!

The startup disk may need repairing.
Try booting from your install disc while holding down the C key.

Firefox crashes upon start up in normal and safe mode

Can't open firefox in either mode, it immediately gives me a crash report pop-up

Did you try to download FF10 with another browser and install it over your current FF version?

My Mac will not start up like normal and I don't knwo why

My iMac will not start up like normal and I don't know why. I tried to run Skype then nothing happend so I tried to restart my computer, but then it never loaded

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 the Recovery partition, or from a local Time Machine backup volume (option key at startup.) 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. Use the working Mac to 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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
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.
Step 7
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.
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 corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
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 8
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 9
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.
Step 10
Repeat Step 9, 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 Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

At odd times I will get a second instance of Firefox startup. I have run avast av, spybot, malwarebytes, both in normal and safe mode and nothing has been found, any ideas?

That second one sounds like malware.
Do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.<br /><br />

FireFox 4 Crashes When Started (Both Normal and Safe Mode)

1. You have a pre-release Beta 1 version of what will become Firefox 4 in like 5 or 6 months. Unless you are intending to test it for flaws and report those flaws to help in the development process, don't use it.
2. Did you create a new Profile for 4.0b1, and are you using that Profile with it? ''That isn't done automatically when you install 4.0b1, and those of us who have been doing the "testing" for many years consider a new Profile as the basis of doing out testing.''
[http://support.mozilla.com/en-US/kb/Managing+Profiles]
IMO, Mozilla is making a huge mistake by directly offering these beta versions to the general public.
Also IMO. if you want to play with 4.0b1, use the Portable Firefox 4.0beta version to minimize any conflicts with a currently installed version of Firefox, and to eliminate the need for creating a new Profile for 4.0 Beta #:
Download Firefox Portable Test to your hard drive and double click the '''FirefoxPortableTest_4.0_Beta_#_English.paf.exe''' file. The entire installation (including a new Profile for "Portable") will be self-contained in the \Program Files\FirefoxPortableTest\ folder and won't interfere with an "official" version that you already have installed. Your Profile will be in the \Program Files\FirefoxPortableTest\Data\profile\ folder.
The "down side" is that Firefox Portable won't launch if any other version of Firefox is already running.

IMac G5 won't boot in normal and safe mode, but will from single-user mode

Hello everyone,
I'm quite new here, so I try to do my best if you have a question.
Yesterday, someone nearby me had a iMac G5 (Powermac8,1), and he sayd, that the computer sometimes will boot, sometimes not.
I did test it, I thought it was running fine, but when I played some music in iTunes, it was stuck on 9 seconds, and crashed (with a kernel panic). The guy also sayd, that there was nothing important on the computer, so a clean install was fine.
Now, the problem is, that it will not boot in normal mode (without anything pressed on boot), also it won't in safe mode (shift-boot), but it will, when I enter single-user mode, mount the hard drive and exit from single-user mode so it will go futher on booting. Sometimes it will not, and immediately gives you a kernel panic in single-user mode, but it will 90 percent of the time.
Then you've got another problem: when it's running in the normal desktop from single-user mode, it'll be stuck after some time again. If I look into the Kernel Panic file created, most times it's because of Spotlight indexing, so I disabled that.
He also gave me the disks (Apple Hardware Test and Extra Applications, and iMac G5 Mac OS X Install Disks 1-3) that came with the Mac. He sayd that I could use them, but I think he didn't test out the SuperDrive, because when I insert a disk, it will try to read, but it will make 2 same sounds, and quits after 10 tries, when it will spit the cd out. Also normal (audio) disks.
Also, I must hurry with the commands for mounting and exiting in single-user mode, or it will just not boot.
In all cases, after 30-45 seconds from pressing the power button, the fan will start blowing at full speed, and it will stop after the exit command in Single-user mode. That's weird.
I can't do anything with the SuperDrive, I can't normally boot in Mac OS X except for Single-user mode (but I don't think he would like to do that every time the computer boots up), and I have very limited time when Mac OS X arrived on the desktop.
When booting in Verbose mode, it will be stuck on this:
AppleSMU::PMU vers = 0x000d004c, SPU vers = 0x15, SDB vers = 0x01,
(and sometimes ends with a kernel crash by fsck_hfs)
Things I've tried (without any success):
- /sbin/fsck -fy (in single-user mode)
- Disabling Spotlight and mds
If you want some more information, feel free to ask!
Greetings
-MrYoranimo
PS: My main language is Dutch, so my English can be bad at some points.

Thank you for your support! This reply is a little bit late, because I was to the camping this weekend.
The only thing I sure do know, is that the iMac has a bad SuperDrive. That's one problem, but I don't really wanna use it, and you fix everything by Single-user mode and when I get to the desktop to test things and change stuff in the Preference Panes.
What also came to my mind was that there also is a problem with the videocard (driver), because sometimes when I boot into Single-user mode, I can see some white pixels which aren't supposed to be there. And when booting from SUM you can see that some of the colors are different and there are weird patterns on the screen.
I also tried to setup a NetBoot server on this computer (MacBook Mid 2010) with just Lion 10.7.4 on it, but I'm not that expert and I didn't really find the good posts on the Internet, although I tried it with the Server applications and both Server applications and DeployStudio. But I didn't succeed.
I don't really like buying a new FireWire hard disk or external FireWire dvd reader/writer, except if it has USB support, because my MacBook doesn't support FireWire, and I really wanna make use of it then.
If I know more or have fixed it, I will surely post again here with what I did to fix it (if no one else has posted here already ).

IMac not starting up (no chime and no USB power)

Hello,
My neighbor's computer is experiencing some problems: it does not start (the screen stays black, no startup chime, but the fans run, as does the hard disk. Also, neither the mouse or the keyboard seem to be powered (no light), so the computer doesn't even come to loading the EFI). The model is an iSight iMac G5 20'' (EMC=2082).
I have tried usual commands (reset PRAM and reset the SMC). Also tried with no device connected. (well, if something so trivial than all these tips did the trick, I wouldn't had to ask here ).
So, without keyboard, I couldn't even try special modes (safe, target disk, start from CD, etc), should the Mac be able to start in some mode. I have then decided to open the iMac (well, the warranty is way out, so nothing is lost). I have never seen a so-hard-to-open Mac, by the way (something was likely blocked).
I'm thinking of 4 possible causes for the problem:
-the hard disk could be damaged. It was malfunctioning some days ago. I assume it could come to a point where the logical board of the disk is failing;
-the RAM is an obvious possible cause;
-the CPU is also obvious;
-another component on the main board/logic board.
-I have forgotten a 5th point?
Well, I tried with unplugging the hard disk, and it had no effect, so it's not the HDD. I'm puzzled for the remaining ones (not knowing the iMac enough is a cause).
First, about the RAM, it seems the RAM slot is empty, so the actual RAM is somehow built-in (I haven't seen something seeming like usual RAM bars), so, if I can't remove the RAM, how can I test whether it's damaged or not?
Then, the CPU. There are 2 of them. So I thought I may take one out (and then the other one) and see whether the Mac starts. Well, I can't figure out how to remove the CPU cooling piece (there are just 4 "buttons" that can be pressed but nothing happen). I prefer asking here first, not removing the entire main board without advices.
Lastly, if it's the main board, I know I won't be able to do much. I have read there are LEDs to possibly diagnose power issues, but I don't see them (no LED is showing light, it seems). I'd like to test my other assumptions before thinking the main board is the cause.
Else, is there something I could try I have forgotten?
P.S: sorry for my (possibly) bad english, and the troubles of explanation; it's not as easy when english isn't the native language. I just wanted to mention that I have already repaired computers, so don't hesitate to tell me complicated answers.
Thanks in advance for your help.

Hello,
Anic,
You can't remove the CPU nor remove/replace the RAM… Really a bad model!
Yes you have to think of it more like a laptop. The only models w/ removable CPUs were the Towers.
Which explains why I thought CPU were usually removable (I have mostly used towers except the original iMac, before).
Thanks. I indeed never touch a board when the computer is plugged.
Hee hee I did since I was used to working on the ALS model where the power supply is enclosed.
Even on an enclosed power supply, I'd not want to touch some kind of board. Well, perhaps it's just me.
Actually, it's the info about which info I need that I'm looking for
After having tried what I could, the remaining bits seem locked (unlike other models).
Not sure what you mean here?
Well, after re-reading myself, I agree I don't really understand either
I meant that I have already tried as much as I could, but the remaining bits (so to mention, the RAM and CPU, mainly) can't be tested. So, I'm looking for testing other parts of the iMac (perhaps there's other things that can be tested, like flashing the EFI).
I'd like to hear from you that the built-in RAM can't be tested, please (to clear my assumption).
the external screen adaptor..(if it wasn't optional, then she does not know where it is).
Well it looks like this. It's pretty standard. Every iBook had one for instance.
http://www.synaptech.com/catalog/images/922-4554.gif
In fact, all the laptops I have seen have that kind of adaptor (although they may slightly vary from models to models), but I thought it was only for laptops (which, as they are easy to move, may have different available screens). Now, does it also apply to iMacs?
I have a question regarding this: I guess the LED3 is concerning the whole graphic card, not just the built-in output, right (in other words, not just about the "main" display)? So I doubt an external screen would make any difference since the LED3 is off (tell me if I'm wrong).
Well what the manual says is:
"LED 3: Indicates that the main logic board has established communication with the LCD display."
So if that's not light then the graphics chip is not communicating with LCD panel.
Fine, but can the graphics chip still communicate with the external port, even if the LED3 is off?
(sorry for having been unclear)
So you did a SMU reset like this:
"Resetting the SMU (System Management Unit)
1. Unplug all cables from the computer, including the power cord.
Wait 10 seconds.
2. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
3. Let go of the power button.
4. Press the power button once more to start up your iMac G5 (17-inch iSight).
Hmm… Not sure about step 2. The "simultaneously" part may not be what I did (I actually tried two things:
1: plugged back the power cord, then (after that) pressed the power button
2: while still unplugged, I pressed the power button (held down for about 5 seconds), then released it and plugged the power cord back.
Do you think I should press the power button while the iMac is still unplugged and keep the button pressed while I plug the iMac (then release the button after I have plugged it)?
If that doesn't help you really need that Mini VGA to VGA adapter so you can plug in a standard VGA monitor and check out the output of the graphics chip (GPU).
I'm glad you mentioned every iBook has one, since my sister has an iBook
I'll ask her.
Since it's not communicating with the LCD it could be a cable problem.
I'm doubting of that, because I'm sure the Mac does not boot at all (not just a blank screen, but also no power on USB ports).
Also you should read through this site:
http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php
Which concerns the "capacitor plague". I'm sure you're aware of this. We had 30 Dell P-IVs that had this problem and those logic boards had a ton of lytics on them.
Hmm… What a charming surprise
Well, I'm indeed aware of this (it hasn't happened to me yet, fortunately).
Thanks for the link.
As to the rest of your questions, answer this set first.
Fine, I follow the guide
Thank you.

Blackberry 9860 stuck in normal and safe mode

after i boot my device,  the device stuck.. i did try boot using safe mode but the problem is still the same.. after a few seconds, it got stuck.. even when i touch the screen, nothing happened.. i cannot get into the desktop software also after i boot my phone.. i cant do anything with it.. what should i do?

Hi and Welcome to the Community!
The simplest way is to, on a PC (you cannot do this on MAC):
1) Make sure you have a current and complete backup of your BB...you can find complete instructions via the link in my auto-sig below. (Moot in your situation, I fear...I hope you have a recent backup already.)
2) Uninstall, from your PC, any BB OS packages
3) Make sure you have the BB Desktop Software already installed
http://us.blackberry.com/software/desktop.html
4) Download and install, to your PC, the BB OS package you desire:
http://us.blackberry.com/support/downloads/download_sites.jsp
It is sorted first by carrier -- so if all you want are the OS levels your carrier supports, your search will be quick. However, some carriers are much slower than others to release updates. To truly seek out the most up-to-date OS package for your BB, you must dig through and find all carriers that support your specific model BB, and then compare the OS levels that they support.
5) Delete, on your PC, all copies of VENDOR.XML...there will be at least one, and perhaps 2, and they will be located in or similarly to (it changes based on your Windows version) these folders:
C:\Program Files (x86)\Common Files\Research In Motion\AppLoader
C:\Users\(your Windows UserName)\AppData\Roaming\Research In Motion\BlackBerry\Loader XML
With that preparation done, please try the use of these tricks. However, if any suggest using an Update Website or any other method, substitute please the use of LOADER.EXE, which will be located at (or nearby) where you found (and deleted) one of the VENDOR.XML files:
KB10144 How to force the detection of the BlackBerry smartphone using Application Loader
KB27956 How to recover a BlackBerry smartphone from any state

Turn off your laptop, unplug all wires, remove the battery, and hold the power button for thirty seconds. Afterwards, reattach the battery and connections. If it still won't start, remove the battery and start with just the AC power. Next try without the AC power and just the battery.
