PC won't boot, everytime i ran chkdsk /f and accept to do the verification next time the pc starts, the pc crashes even in security mode.

So here is the story:
One day, the energy went down. Since then the pc would only initalize in safe mode, if i do it normally i received a blue screen in the loading process. But now, only inititializes in safe mode with prompt. The other ones i got stuck in classpnp.sys (yeah,
safe mode don't work anymore).
I ran scannow, and didn't found any problems. But, after i ran chkdsk the OS found some problems and asked me to run chkdsk /f . I ran it, and choose to initialize the scan when i restart it. But that's the thing, it crashes before anything, and when i ran
again in safe mode with prompt, no verification is made and chkdsk give me the same error message!
Resuming: I think chkdsk /f would solve my problem, but the system crashes before anything.
I can't find any cd to repair it (windows 7 ultimate), and since i can't initialize it in anyway but security mode with promp i also couldn't make a repair cd. I work in a lab, and the HD have some really important files.
Can someone please help me?
EDIT: I ran chdsk/f and chkdsk/c through the command prompt in the recovery mode, and still have all the same problems.

And althoug the chkdsk through repair mode wasn't finding anything wrong, when i ran it in "safe mode with prompt" i had the following error:
"Bitmap volume is incorrect"
edit: I executed the diagnosis tool from "western digital" and no error was found. Should i still use MHDD? Starting to lose my hope. I'm accepting ANY IDEA.
Have a look at this page in reference to the error message you see.
In view of the special nature of your PC, your predecessor was badly negligent in at least two regards:
He should have created, maintained and tested an image of the system partition so that he could trade out of problems caused by a defective disk, a damaged file system or a virus infection.
It is mandator to maintain proper records of all installed software, in particular:
- Name of software, where purchased, price paid.
- Licensing details
- Where the installation media are kept
Whenever I hand a new machine to a client I retain an image and copies of the above details.

When you complete your current contract, Verizon has options on which incentives you would like to take.
You can sign a new 2 yr service contract by purchasing a new phone at a considerable discount(~$400+).
You can also choose to purchase a new smartphone on Edge at full retail cost for which Verizon will give you either a 37.5% or a 62.5% discount(depending on your data allowance) on your monthly line access fee when on the More Everything plan.
If you choose to simply continue using your current phone on the More Everything plan, Verizon ALSO offers the same 37.5%/62.5% discount(depending on your data allowance) on your monthly line access fee.
Of course, as with anything else, there are some which always want more of a discount than what is offered.
Hopefully, after you get used to the rates with your new provider, you won't then want MORE which they likely won't be willing to give you.
Good luck with the new provider.

My ipod touch 2nd gen 8 gb won't boot! (I did hold home and power)

So my ipod touch 2nd gen 8 gb won't boot. It never really fell on the ground it was not jailbroken and I had it for almost a year. Yes I have googled it, yes I holded home and power button at the same time, basically did almost everything possible. I'm thinking it's the battery but might be something else. If you recognize this problem and know how to solve it, please reply here. I also can't connect to itunes in case your wondering

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

IMac freezing now won't boot up circle keeps going round and round

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

IMac won't boot correctly! Braille-looking screen and purple lines

Hi guys; i've got a big problem over here; about a week ago my iMac (27", late 2009, i5 2,66ghz quad core, 4gb RAM upgraded to 12, running Snow Leopard) froze while watching a movie in streaming. After a few minutes i decided to force the turn off and pressed the power button. When i turned on again the computer it boot up showing this braille-looking screen instead of the desktop.
The first thing i performed was the safe-mode-startup, and that worked fine; when i turned on in 'normal' mode again everything worked correctly.
After a few days it happened again, but this time on the white boot screen with the apple logo there were several purple lines 'organized' in five groups.
On the light blue screen, wich is next in the boot-sequence, the lines disappeared and at the end of the boot, instead of the desktop, there was braille-looking screen, but this time with some purple dots.
The first thing i did this time, too, was safe-mode-boot, but that didn't work fine as the last time, in fact i achieved to log in and use the computer, but the purple lines kept on staying over the background (and their color is influenced by background color eg.. if the desktop is orange the lines turn green). Then i switched off the computer and tried to boot in 'normal' mode, but nothing changed from the situation before the safe-mode-boot.
So i tried everything that came to my mind: Repair disk in the Disk Utility; Reset PRAM; Reset SMC; Remove the 8GB RAM i added, i even removed the HDD and replaced with an SSD that i was planning to put in the computer for an upgrade, but nothing worked.
I am asking for your help guys, every tip to solve the problem is appreciated, i thank you in advance.
ps: i apologize for my english, i'm not a native english-speaker

I would definitively exclude display failure because the light-blue screen is just as normal as it should be, and i would also exclude that i made damage installing the ssd since nothing change from before installation to after; probably the GPU is failing and i should take the computer to an apple store; that is a pity for a 4 year mac. At the moment i'm recovering my logic pro files from a macbook, i will go to the apple store during the week. I thank you anyway for your tip.

Can't Boot after crash, even in safe mode!

My Mac froze while idle with Lightroom open. It may have hung while remotely copying something off an external hard drive.
But now it won't boot even in safe mode with all USB peripherals detached (including the hard drive that I might have been copying from).
In and out of safe mode, I get the same behavior. After the sound and the grey apple appear, there is also a progress bar, which I don't recal seeing before. It takes about 30 seconds and the progress bar advances about 10-15% of the way and then just power's off.
Is it the main disk drive?
This is an iMac that is several years old with all of software update applied. I don't believe that any software updates were applied recently. I assume that the 10.6.3 update was installed.
Is it the main disk drive?

I had the same problem on my MacBOOk Pro and iMac on 14th April - i had to reformat the harddisk and could restore from my Timemachine backup to the last 10.6.2 state only. Both happended after updating to 10.6.3. But my laptop was sluggish. Based on feedback, I reformatted my hard disk and carried out a fressh installation from my snow leopard disk (10.6) and updated it to 10.6.3 using the 10.6.3v1.1 combo update about a week back. The machine was definitely faster - but yesterday, the same problem reoccurred - the machine froze and would not boot even in safe mode. Repairing the hard disk using the boot CD did not work either. Just now I reinstalled Snow leopard from the OSx CD - it has replaced the OS and left all apps and data intact. I have upgraded it to 10.6.2 only.
My desktop iMac has been running without problems on 10.6.2 for the last 3 weeks. In my opinion, the problems of freezing (reported by others) and this one here are all related to boot sector corruption due to some problem in 10.6.3. There have been some reports suggesting that after 10.6.3, the CPUs are heating up more. The CPU temp was close to 70 deg C when on 10.6.3 - it maybe that some change after the update makes the processor overrun leading to this boot sector corruption - it generally happens slowly over days or weeks slowly accumulating to a break down point.
My suggestion from my experience over the last one month, is stick to 10.6.2 - don't update to 10.6.3. I am hoping Apple will fix the problems in 10.6.3 update soon.

I paid for and tried to download the song "Cryin" by Aerosmith but it won't let me download the song each time I go to the store and click on available downloads, it looks like it's downloading and I get an error message that the file is corrupt

I paid for and tried to download a song from itunes but the song won't dowload! When I got to store and click on available downloads it looks like it's downloading but I keep getting a message that the file is corrupt.

I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not downloading properly. If you can't see "Report a Problem" next to the entry, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)

MacBook Pro won't start after upgrade, not even in recovery mode

So here is what happened:
Yesterday, the app store icon told me that one update was not installed yet,because I need to restart the computer first (hard for me to reconstruct now, because I didn't really read it carefully, which I should have done, but Apple"just works™", so hey, why should I ). So I restarted the computer. This is where things went very wrong. Eventually during reboot, text appeared on the grey Apple logo screen, it looked like verbose boot mode, but overlaid on the "regular" grey boot screen with the  logo. Before I could read, what was happening, I got a kernel panic with the "hold down the power button to restart".
Holding down the power button took me to the login/file vault unlock screen (I have my disk encrypted). Unfortunately neither keyboard nor trackpad worked. So I held down the power button again, which brought me back to the login/file vault unlock screen.
At this point I noticed that it said in the lower part of the screen that, in case I had problems to enter my login information, I should press the power button for a long time and then again for a short time to get into recovery mode (this is all from my memory, I might not recall it exactly as it happened).
This made things kind of worse, it showed me the Apple logo with the progress bar, which advanced to about a third or a quarter, then the progress stopped and I ended up on a grey screen with a grey crossed circle in the center (looks kind of like an european no parking sign).
I tried booting into recovery mode by holding down the R key. This brings me to the progress bar and the subsequent grey screen.
I tried to boot into my time machine, by holding down the option key. This gets me to the boot volume selection, I can choose my time machine volume (external FW800 drive), but it does not use this volume to boot (I can hear that the external disk is not spinning). Instead I get the above mentioned behavior (progress bar, grey screen).
I tried to boot into target disk mode by holding down the T key. This only works, when I connect an external USB keyboard. This way I could use another computer to recover my important files (which is good). I could also peek at the logs. It seems as if the failed boot attempts do not produce logs. But I have the system log from the "restart to install update" process. The last few seconds or so I get a lot of these messages:
Feb 3 14:33:51 Larss-MacBook-Pro kernel[0]: Refusing new kext com.apple.kpi.libkern, v14.1: already have loaded v14.0.
I use a Macbook Pro 13" early 2011. I don't know the processor speed, because I cannot boot it. I guess it has 8 GB Ram (pretty sure I maxed it out).
I have an SSD installed (I replaced the original HD with a 1GB Samsung SSD). There is another post here, which sounds similar, but I definitely did not use "Trim enabler" or similar third party software.
I use Yosemite, I think I was pretty much up to date, I suspect the reboot was for the 10.10.2 installation, but I am not sure (I simply didn't look when I hit that reboot to install button).
Yosemite on SSD wont boot and wont go in safe or recovery mode
Anyone any ideas? Any help is appreciated!

So I just went through the install.log.
First of all, there I found out that I have a MacBook Pro (13-inch, Mid 2010):
Feb 3 14:31:12 larsmbpro.domain.com suhelperd[336]: GetModel: model = MacBookPro; major rev = 7; minor rev = 1

"PKLeopardPackage <file:///Library/Updates/031-17157/OSXUpd10.10.2Patch.pkg>",

The last messages in this log are:

According to the system.log, the shutdown happened 14:33:08. The boot time is 14:33:24, no log entries between 14:33:08 and that time. 16 seconds seems awfully long for a reboot:

Power Mac G4 Won't Boot after Installing 2nd Hard Drive and Additional RAM

Hello. I am using a Power Mac G4 (PCI graphics) that I bought a few weeks ago. It was working perfectly fine until I tried to add an additional hard drive and add more RAM to the machine. After I closed the case and plugged it back in, it won't start up at all. No sound, no lights, nothing spinning, nothing. I removed the added hard drive and RAM, but it still refuses to start. I don't know what happened. Hopefully it's not a logic board failure or anything else equally bad.

Welcome to Apple Discussions!
The PowerMac G4 PCI forum is over here:
http://discussions.apple.com/forum.jspa?forumID=586
I'll ask a moderator to move your thread. Try replacing the clock battery, and hitting the CUDAS switch.

IMac won't boot, hangs on white logo screen and wheel stops spinning

I have a 4 year old 24" iMac - 4GB RAM, Lion 10.7.3 - that froze up in the middle of opening a PDF file in preview. I powered it off by holding in the button only to discover it will not restart. It gets as far as the white screen with the Apple logo and the "spinning" circle of lines and the this stops spinning after about 15 seconds and it will not do anything else.
I have tried:
resetting the SMC
resetting the PRAM
Booting:
with only keyboard plugged in
in safe mode
from USB (Lion) Recovery thumb drive
from MBP in target mode
from Time Machine backup
from Leopard and Snow Leopard DVD's
In all cases with the boot the HDD is shown along with the other drive(s) connected and I can select these other drives but the result is always the same. In safe mode it just hangs after going through everything.
As the iMac isn't under warranty I decided to swap the HDD out with a 1TB working one from my old (deceased) Time Capsule. I know this drive still works. Still the same problem though. Whilst the imac was apart I checked the onboard CR2032 battery was OK and for any obvious board problems. Nothing.
I haven't been able to find anything that relates to not being able to boot of an external drive from searching the web and I now conceed this is most likely a board level failure. I haven't lost anything as I backup routinely. My intention was to upgrade when the next model iMac comes along, just wish it ends up being very soon as my MBP is not great for editing photo's.
If I could get the iMac limping it would help whilst I wait for the next generation iMac, so if anyone can help it would be appreciated.

My macbook pro (A1260) won't boot; powers up for 3 seconds and then shuts down.

Just recently my MBP A1260 gave up on me. When I push the power button, the dvd drive and hard drive both start, but the screen remains black. After 3 seconds, the hard drive makes a click and the whole laptop powers off. I suspect the hard drive has failed due to the click it makes, and I've had hard drive issues in the past.
If the hard drive was the issue though, wouldn't the screen with a folder and question mark come up and the laptop stay on? That is what's happened in the past. I just took it to the apple store to have them look at it and they suspect the logic board. However, I was wondering if there was anything I could do to confirm this. I don't like the idea of spending $400 to repair, but I will if necessary. I also read that this model of MBP has issues with the Nvidia chip and the repairs would be free if this was the cause. Is there any way I could be sure it's the Nvidia chip, or any suggestions to get some life back in my MBP?
thanks in advance!

Apple repair is going to be your best bet. If it is the NVIDIA GeForce 8600M GT graphics processor that is built into the logic board, and fails within four years of the original date of purchase, a repair will be done free of charge.

Hello, My i Mac is from 2008, the unit at times doesn't start up.(mouse lights then off with no screen) I ran Mackeeper thinking its a virus, but not. My unit is plugged into a volt regulator its a US unit 110v and here in philippines 220 V, any ideas

Hello, My I Mac is a 2008 unit. Quite offen it will not power on, mouse lights then it goes off with no screen even if i press control/command rp keys.
Some other information the unit is from USA, a 110V and now in Philippines which is 220V I have it on a 110 voltage regulator.(can i plug in to 220 v directly?) I also ran MacKeeper thinking it could be a virus, but its not, i notice if i leave unit on without shut down, the problem occurs less, thinking its a battery problem but I'm not sure.
Here in Philippines we have no Mac stores and service is not like in the USA. Any ideas of what wrong?

MacKeeper is highly invasive malware that can de-stablize your operating system. It is also unethically marketed and a rip-off.

When i buy something for itunes on my itouch 4th generation, it won't let me download the song saying that i have invaild address, and i have retyped the address many times. This is the first time that this has happened. What do I do?

Help me please!

Do you currently have a credit card set up in your iTunes store Enter Payment Information screen?
If so, grab a recent statement for that card and check to make sure that the address that shows up in your Enter Payment Information screen exactly matches the address showing on your credit card statement. For example, if your address in the credit card statement says "Street", the iTunes screen has to also say "Street" (Not St or Str.) Also match the capitalisation of the address on your statement. (If it says STREET in the statement make it say STREET in the iTunes screen, not Street or street.)
Also make sure that your name in the iTunes screen exactly matches the one in your statement. (Say, if you've got a middle initial in the credit card statement name, you need one in the iTunes screen.)
After doing that, does that get you past the invalid address thing?
If not, there's some additional suggestions in the following post:
