My ipod won't start up even though i press all the buttons and i have already tried pressing the middle and the menue button

Try hard resetting it: For a "scrollwheel" iPod, press and hold the middle button and the menu button at the same time for a few seconds. For an iPod Touch, press and hold sleep and home at the same time for a few seconds.

Try reseting it. Hold down the "Menu" button and the middle button for about 7-8 seconds. The apple logo should appear, then just wait about 5-6 seconds for your ipod to start up again.

Hope this helps!

press the MIDDLE BUTTON and MENU button at the same time

or

press PLAY and the MIDDLE BUTTON at the same time till you ipod resets

Try forcing the iPod into disc mode to restore.
Putting ipod into disc mode http://support.apple.com/kb/HT1363 Toggle the Hold switch on and off. (Set it to Hold, then turn it off again.) Press and hold the Menu and Select buttons for at least 6 seconds until the Apple logo appears. When the Apple logo appears, release the Menu and Select buttons and immediately press and hold the Select and the Play/Pause buttons until the Disk Mode screen appears.
Connect the iPod to your computer; the screen on the iPod will change and say "Do not disconnect" If you are having difficulty putting the iPod model into disk mode, set it on a flat surface. Make sure that the finger pressing the Select button is not touching the Click Wheel. Also make sure that you are pressing the Play/Pause button toward the outside of the Click Wheel and not near the center.
If you are still unable to put your iPod with a Click Wheel into Disk Mode, use one finger from one hand to press the Select button, and one finger from the other hand to press the Play/Pause button.
If this does not make the iPod connect to your computer, I would suggest checking out www.rapidrepair.com for further ideas and options to your issue.

You will want to attempt to force the iPod into disc mode then restore using iTunes. With the iPod in disc mode, iTunes should show the iPod. You will have to restore the iPod to resolve the issue of corruption though. Please let me know if this does not resolve your issue. :)

How to restore iPod (ARTICLE NUMBER HT1339)
Open iTunes, and then connect your iPod to your computer using the USB or FireWire cable that came with your iPod.

After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel and you will see information about your iPod appear in the Summary tab of the main iTunes windows.

Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download the latest iPod Software.

The 4 possible restore options are: Restore Option

1: Restore - Restores with same iPod Software version already on iPod. Restore Option

2: Use Same Version - Restores with same iPod Software version already on iPod even though a newer version is available. Restore Option

3: Use Newest Version - Restores with the latest iPod Software available. Restore Option

4: Restore and Update - Restores with the latest iPod Software available.

If you are using a Mac, a message will appear prompting you to enter an administrator’s name and password.

A progress bar will appear on the computer screen indicating that the first stage of the restore process has started.

When this stage is completed, iTunes will present one of two messages on screen with instructions specific to the iPod model you are restoring.
Restore Instruction 1: Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).


Restore Instruction 2: Leave iPod connected to computer to complete restore (typically applies newer iPod models).

During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage.

Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.

After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

Press and hold the center button while holding down the menu button. This will reboot your Ipod. Check your IPod cable to see if its shorted. If might have transferred a song and crash in the middle of the transfer.

- check the cable - check the connections on the bottom of the ipod for bent pins, or dirt - make sure ipod battery is fully charged - if you have all your library backed up, reset ipod to factory. You will lost all settings etc. though. - check usb ports are working properly with no conflicts or driver issues (control panel\system\hardware\device manager) - uninstall usb ports on pc, let pc redetect them
