30gig ipod video keeps resetting itself

my 30gig ipod video keeps resetting until it runs out of battery life, if i have it connected to my pc, it just keeps resetting indefinately, and if i disconnect it, it does so until it runs out of battery.
i've already reset it manually, returned it to factory conditions, I dont know what else to do, any help at all would be appreciated.

Hello eonitwat,
And welcome to Apple Discussions!
Try manually forcing the iPod into Disk Mode and then reconnecting to your computer. This might prevent the iPod from continuously rebooting to allow you enough time to try and reformat the iPod completely using the tools provided by Windows.
Here are instructions on how to reformat your iPod on WIndows. The instructions are for Vista and XP, but you'll find that Windows 7 is very similar to Windows Vista.

If still no luck, you may want to consider having the iPod serviced.
Worth a shot.

My ipod touch keeps getting restarted. Be it while playing games or listening to music. Whats the problem here?

My ipod touch keeps getting restarted. Be it while playing games or listening to music or browsing thru the app store. Whats the problem here?

Oh, you do one thing, back up your iPod to iTunes. Plug your iPod to the iTunes and when it appears under devices tree on the sidebar, right click on it, and back it up.
After the backup completes, jus click on restore button. If required it will download the latest iOS from the servers (Might take sometime) and after it's downloaded, it will erase all your data and settings, restoring to factory settings.
After you have completed restoring the iPod, jus set it up as new iPod.
Sync back all the apps, music, movies.
And make sure you quit the apps, by double clicking the home button and pressing and holding the app icons and clicking on
This should help your problem anyhow!
It might be a case that the files in the apps, or the preferences might be corrupted, jus to be safe, we have a backup.

Ipod video keeps trying to restart.. HELP!

hopefully someone can help me fix my ipod without deleting all my files, which i cannot download agian...
i tried to change my ipod video to the ipod classic, after loading the classic firmwire in ipodwizard, my ipod has been trying to reboot over and over,it just keeps starting up and shutting off. can any body help me?
thanks..

That solution works, I had actually posted my problem with my ipod continuously trying to restart and never being able to restart. The other post's solution is correct, it will allow you to connect to your computer and itunes will recognize your ipod, restore it (yes you'll lose everything, I'm sorry and I know it stinks but it's the only thing I have found that works). The only issue I had with the solution was when I clicked restore on itunes it would say that the ipod can't be restored because of some unknown error 1429. So to go around this issue, go into disk mode connect the ipod to your computer, and it'll say that it needs to be restored. Once you click restore, immediately follow the same steps to put your ipod in disk mode to take it out of disk mode and your computer will be able to restore your ipod. I know the solution isn't the greatest because you lose your data but at least your ipod works again.

Ipod Touch 5 random restart and wifi connectivity issues

Good day to you sir...
My Ipod Touch 5G 32gb model white has issues towards random restart and wifi unstable even though I have full bars and a working wifi internet connectivity
Here are details that might help on my case..
I bought the Itouch 5 on singapore exactly around January 2013 registered on January 1 on Apple web for warranty.
Around early Feb, i experienced some random restart and I tought it was just some bug after update, it was gone and came back around late march with some wifi issues, but not regularly, only around certain cases on using it for a long period of time. I am still experiencing it now.
The device never experienced drops,dents, nor water damage.. it is protected by an Ozaki case and screen protector bought in a Mac store. Never been Jailbraked. I used it for music, videos and gaming purpose. I have 3 idevice other than the Itouch (iPad 2, Ipad w/ retina display and Ipad Mini with no occuring problems both updated to ios 6.1.3 (so is the itouch). I would like to know what course of action should I take about this problem. I have restored the Ipod Touch 5G via iTunes but the problem still occuring both wifi and random restart. I bought the device on a legit mac authorized dealer. (Power Mac i think) in Singapore, but I live in General Santos City, Philippines. I would gretly appreciate if you give me exact details what course of action should i take.
P.S. my Ipod Touch 5 is running on iOS 6.1.3..

If you restored to factory settings/new iPod and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

30gb ipod video keeps on crashing

I just got my ipod video 3 days ago and I keep on having a problem where it will play a video for variable amounts of time and just all of the sudden crash. After this, when I push a button it will restart back up with the apple icon. I've read quite a few posts with people having the same problem but there hasn't been a good solution as of yet. I've tried firmware versions 1.1 and 1.1.1 with no success. I don't think that this is the same problem with a video playing for 30 seconds and then the video and audio stops. The ipod will also sometimes just crash when I'm using the menu or when I'm playing songs.
This has really been frustrating me. Any help would be appreciated.
Thanks.

30g Ipod Video keeps rebooting

I just got the new Itunes 9.0 and synced my Ipod video as usual, but now it just keeps rebooting and is stuck on the black screen with the white apple.
I have tried (twice) going into disk mode, and restoring the Ipod, but it still has the same issue. I have also tried plugging it into a wall charger.
Any help would be appreciated Thanks in advanced!

probably the next best thing to try is attempting to reset it while it is connected to a power source (like the PC). see:

My 2007 iMac keeps randomly restarting.

Running latest Mavericks on my late 2007 iMac. Recently had to do a Time Machine recovery and since my machine randomly restarts by itself when left unattended. While monitoring Console the following message keeps repeating and suspect it is the root of the problem.....
6/26/14 5:04:46.570 PM com.apple.launchd.peruser.501[225]: (com.hp.help.tocgenerator) Throttling respawn: Will start in 10 seconds
6/26/14 5:04:47.607 PM com.apple.launchd.peruser.501[225]: (com.hp.help.tocgenerator) Throttling respawn: Will start in 9 seconds
Any idea's what this means and what would be causing ?
Thanks for any help.

You apparently have some possibly incompatible HP software installed. Note the filename: com.hp.help.tocgenerator. I suggest you uninstall any HP software you now have installed on the computer after which you will need to restart. What would be more helpful: Mac OS X- How to log a kernel panic.
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper
    2. AppDelete
    3. Automaton
    4. Hazel
    5. AppCleaner
    6. CleanApp
    7. iTrash
    8. Amnesia
    9. Uninstaller
10. Spring Cleaning

Ipod video crashes randomly...

I have a white ipod video 30 gb 5g and I would be playing a song when all of the sudden the screen freezes. The song keeps playing till the end but after that the next song doesnt play it would just freeze everything. Anyone know whats wrong? Every time this happens, I have to restart the ipod (menu+center) but this drains the battery so much..

Yes. I have restored it, restarted it, done everything I could think of and nothing. It seems as if its something else. I'm thinking that it could be the battery giving off different amounts of voltage but I don't know.

Macbookpro Keeps Randomly Restarting

My Computer's Details - http://pastie.org/private/u9w6mgnlzbafxcil31l1w
Hello, I recently have been on my MacBook Pro and two nights ago while I was closing a application my computer randomly restarted and I thought that it was kinda weird while it was restarting it asked for my password, I typed it in and it restarted again before my computer even fully loaded. Then when I woke up the next morning I opened my laptop and it restarted and said "Your Computer Restarted because of a problem" so it's been restarting the whole day yesterday and today, and another thing that makes it restart is when I plug my Iphone 4s into it. Here is the message
"Your computer restarted because of a problem. Press a key or wait a few seconds to continue starting up."
once it opens it restarts again and then I get this once it opened fully - http://pastie.org/private/edlnqjczaw0oaptamtn3g
If anyone knows the problem please help me it is getting very annoying.

Hello!
What's happening to your Mac is called "kernel panics"
They can have many causes. Often they're caused by connected peripherals. If you have any connected, including external display, disconnect them. See what happens with a barebones MacBook Pro with other words.
Secondly, you have these non-original kexts/drivers. If we manage to get you back into your OS X again, you must consider deleting the ones below:
com.paceap.kext.pacesupport.snowleopard 5.9.1
com.microsoft.driver.MicrosoftMouseUSB 8.2
com.microsoft.driver.MicrosoftMouse 8.2
com.sophos.nke.swi 9.2.50
They can be found at: "/library/extensions"
If your issues aren't solved by disconnecting peripherals, here's my advise. It's a bit lengthy but might just save your day:
It will take you about 45 minutes or less to do these, depending on how bad the problem on your Mac is as well as your internet-connection speed.
The goal here is to boot your Mac to the so-called Internet Recovery partition where you’ll have a chance to repair the disk and the disk permissions using the Disk Utility and Password Utility. This might solve your issue and even if it doesn’t- it’s still a decent maintenance step to perform. These steps won’t erase your data or reinstall your Mac in any way if you follow instructions carefully. Make a back-up anyway.
Here’s how:
1/ Make sure your computer is completely shut down.
2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [alt] + [cmd] + [r] Keep these keys on your keyboard pressed until you see a spinning globe with the text “starting Internet Recovery” You might have to connect to your Wi-Fi network before you can continue here.
After a few minutes, you’ll be presented with a Utilities screen. This is the Internet Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
3/ Choose Disk Utility and click [continue]
Disk Utility will display your computer’s harddrive in the left column. The default name for it is “Macintosh HD” and is usually the second one from the top. Click on it and click on the [verify disk] button. This will check your “Macintosh HD” harddrive partition for errors. If found, click [repair disk] unless you have a Fusion drive in your Mac and it says [fix] instead of [repair disk] please tell us before you continue! For a screenshot of what I mean, check this article from Apple: http://support.apple.com/en-us/HT202574
4/ Once done with the verifying or repairing of your “Macintosh HD” click [repair disk permissions]
This will check your partition for permissions errors. A common myth about this feature is that it will fix all permissions issues on your Mac, which is not true, but it will fix most systemwide issues. Also, here is a list of error messages that you can safely ignore if they pop up:

5/ Lastly we shall do a permissions/Access Control List repair on specifically your user’s home folder with a somewhat hidden tool in the Recovery partition. Close Disk Utility and find the menu called “utilities” in the top left corner of your computer’s display. It’s in between the menus “edit” and “window” Don’t be confused with the menu called “os x utilities”
Choose Terminal. A somewhat old-fashioned looking window will pop up, waiting for a text command from you. This is the Terminal.
After the # type: resetpassword and press return. Note that there is no space between ‘reset’ and ‘password’
What you’ll see next is an rectangular window that gives you the option to reset passwords. We are not going to that, however. Instead, click on “Macintosh HD” at the top. In the pull-down menu below that, choose your user's accountname. Skip all the rest and at the very bottom click the [reset]-button.
A spinning gear will appear and may stay on for a second or several minutes. It’s hard to predict exactly how long.
If you have multiple users on your Mac, I advise you to repeat this step for all your users.
We’re ready to reboot your Mac now. Click on the Apple Menu and choose “startup disk” Choose to boot from “Macintosh HD” Please let us know if this solved your issue, or if the steps above did not work, or could not be performed for some reason.

I am sad with my ipod video 30GB...HELP!

after i found a disclaimation mark icon diplays on my ipod vedio, i tried to upgrade and retore my ipod video with most updates ipod updater 1.1.1 version. it doesn't work!; it told that "cannot retore", so i use the Mac's application - Disk utility to erase the disk. the process took 30 hours to finish. i restart my ipod and mac.
but after that, ipod still cannot mount on to my desktop. my OS X 10.3.9 ask me to "format/ignore/eject" after restarted. i press "ignore" to make ipod connect to my mac. open my ipod updater to retore it again , it runs a moment and told "error while format ipod"!
i have NO idea to fix it, anyone can help?
or i just send it to the apple warrenty center?

If i was you i would just send it away to apple because you are obviously trying everything you can to fix it and nothing is working.
Even if you just contact apple via email or phone they can maybe suggest other options.
