Well you can reset from the "backup and reset" menu that you can see in the picture. That will erase all user data and apps, so if the problem is that there are corrupt data in the device that will fix it, so it's certainly worth a go.
What a reset does not do is reinstall the OS or undo any software corruption. Just want to make that clear, since many people misunderstand what it does.
Is the device new, or did you get it second-hand?
