It sounds like you either reset your iPod to factory settings, OR you just bought a new iPod! Either way your iPod is telling you to connect it to a computer with iTunes on it.
Step 1: Go to http://www.apple.com/itunes/download/ and download iTunes.
Step 2: After it is done downloading, install iTunes by double clicking the file you just downloaded. When a screen pops up with a button labeled "Next", continue clicking it until you reach the "Finish" button.
Step 3: iTunes should automatically open up, if not, open it from your Start menu, or desktop.
Step 4: Connect your iPod. After a few minutes, iTunes will prompt you with a Welcome Screen with a picture of an iPod, follow the on screen directions and you will be able to use your iPod.

What do you mean, start? Have you opened an ITunes account, What do you want to get out of the Touch?

There is only one way, you must restore the ipod which wipes out everything if you forgot it.

Updating and Restoring iPod touch Software
You can use iTunes to update or reinstall iPod touch software, restore default settings, and delete all data on iPod touch.
• If you update, the iPod touch software is updated. Your downloaded applications, settings, and data aren’t affected.
Note: In some cases, an update may also include restoring iPod touch.
• If you restore, the latest version of iPod touch software is reinstalled, settings are restored to their defaults, and data stored on iPod touch is deleted, including downloaded applications, songs, videos, contacts, photos, calendar information, and any other data. If you’ve backed up iPod touch with iTunes on your computer, you can restore data from the backup at the end of the restore process.
Deleted data is no longer accessible via the iPod touch user interface, but isn’t erased from your iPod touch. For information about erasing all content and settings, see “Resetting iPod touch” on page 122.

Start by syncing your iPod with your computer. When you do this, the iPod management screen will appear. Midway down that screen there's a button that reads "Restore." Click the restore button. This begins the process of restoring the iPod to its factory settings. After you click the restore button, iTunes will ask you to confirm that you really want to do this. If your iPod content is backed up, go ahead. The iPod restore process includes iTunes downloading and installing iPod software and bug fixes. You will see a window that looks like this. Follow the onscreen instructions. On a Mac, you will be asked to enter your computer?s password. On Windows, the installation will just proceed. As iTunes restores the iPod, you will see a progress bar. After the restoration process has completed, iTunes will pop up a window letting you know that it?s done. Now you?ve got an empty, freshly formatted iPod. Now you can sync the iPod with your computer and download your iTunes library again.

disconnect ipod n hold down pwr & menu buttons until apple logo appears on ipod screen

you have a software cooruption. the only way to fix this is to do a restore. try plugging it into itunes and see what happens. if itunes recognizes the ipod it will tell you to restore it. if itunes does not recognize the ipod you need to unplug the ipod and turn it completely off. then you need to plug the ipod while holding the home button down until itunes recognizes the ipod and then it will tell you to restore it.

here's how:
1. Turn on your iPod (in my case it would only get as far as displaying the Apple logo
2. Hold the power and home buttons down (the iPod will power off after 10 seconds, but keep holding those buttons down)
3. After the iPod powers off, release the power button (but keep holding the home button down)
4. After a couple more seconds, you should hear that magical “ding dong” that means the iPod is coming back alive, and that Windows has detected it. You may even see a little “New hardware” popup in Windows. It is now safe to release the home button, and your iPod is in DFU mode.
5. Now iTunes will see it as a DFU’ed iPod and should ask you to automatically restore its firmware.
6. iTunes has to download the new firmware, and it takes a while, so go make a sandwich.

try putting your ipod in DFU mode. after putting your ipod in DFU mode restore it. that will the problem.
