Hello Johnbe2,
It sounds like you cannot open iTunes, as it only runs for a couple of seconds before becoming unresponsive. I can understand it would be frustrating to not be able to sync your phone or get to your media. Try opening iTunes in Safe Mode to help troubleshoot the issue named:
iTunes for Windows Vista, Windows 7, or Windows 8: Fix unexpected quits or launch issues
http://support.apple.com/kb/ts1717
Open iTunes in Safe Mode to isolate any interference from plug-ins or scripts not manufactured by Apple.
- Hold down Shift–Control while opening iTunes. You should see a dialog that says "iTunes is running in safe mode" before iTunes finishes starting up.
- Click Continue.
- See if the issue you're experiencing persists in Safe Mode.
If you have the same issue while iTunes is in Safe Mode, proceed to the "Create a new user account" section. If you don't experience the same issue, follow these steps to remove third-party plug-ins.
By creating a new user account, you can determine if the issue affects a specific Windows user account or all accounts. Follow the steps below to create a new user account in Windows Vista or Windows 7:
- Choose Start > Control Panel.
- Open "Add or remove user accounts." (If you're using the Classic view in Windows Vista, open "User Accounts," and then open "Manage another account.")
- Select "Create a new account" and follow the instructions to set up the account.
- Once you create the new account, choose Start > Log Off.
- Log in to the new user account.
- Open iTunes and see if the issue you're experiencing persists in this new user account.
There is more troubleshooting to be done if needed in the article, up to and including reinstalling iTunes. If it comes to that, there is a walkthrough to uninstall not just iTunes but its associated softwares as well for a fresh, clean install.
Thank you for using Apple Support Communities.
