Q: all of a sudden my iTunes will not load. any suggestions?

Hi jd-obrien,

Thanks for contributing to the Apple Support Communities. 

If iTunes doesn't open on your PC, first press Ctrl + Alt + Delete to see if iTunes is unresponsive and needs to be quit and relaunched. I'd also recommend restarting your computer since iTunes was working earlier in the day. 

You can also use the method in Fix unexpected quits or launch issues in iTunes for Windows to troubleshoot iTunes if it still won't open. 

All the best. 

Hi jd-obrien,

Thank you for your reply. 

I'm glad that Joe's steps solved the initial issue. It seems like iTunes is launching now, but your iPod nano isn't recognized when you connect it to your computer.

To troubleshoot this situation, I recommend going through the steps in iPhone, iPad, or iPod not recognized in iTunes for Windows. 

Safe Computing.
