Probably something went wrong, and your iPhone itself sees that too. That's why your iPhone asks to connect it to your PC or Mac with iTunes installed.
-Start iTunes on your PC or Mac
-Connect your iPhone to the PC or Mac
-Probably iTunes will advise to recover your iPhone.
>>If you didn't make regular backups of your data you probably will lose the data that's on your iPhone.<<
-Wait until the recovery procedure is done and see if your iPhone works again.

What if iTunes doesn't recognize your iPhone anymore in iTunes?
Thy a "soft reset' by pressing the ON/OFF button on top of your iPhone and the round menu button underneath your screen simultaneously until your iPhone reboots. Check if your iPhone connects to iTunes and try the recovery.
I hope this will help you solving your problem.

You have a situation where your phone needs to be recovered by plugging it into the computer where you sync it to iTunes. When you do this a prompt will come up on your computer that you have connected to an unidentified iPhone. It will ask you if you want to restore it from your last backup, or initialize it as a new iPhone. I recommend that you restore to the last backup, so you don't have to go to the iTunes and App Store to reinstall all your apps. The bad news is that if you have never backed up to a computer, your journey to recover your digital life is going to be difficult.

Try pressing down the off button and the menu button on the iphone at the same time to reset the iphone. If itunes keeps freezing try uninstalling itunes completely, then go to the apple website and download the newest version of itunes. if that still gives you trouble try not to upgrade itunes while iphone is plugged in.
