Welcome to Android Central! It would be helpful to know what exactly you tried, so that people don't suggest the same thing to you.

Try booting into Recovery Mode and wiping the cache partition. This process can take up to 10 minutes on a Nexus 5, so let it run. http://forums.androidcentral.com/nexus-5-rooting-roms-hacks/352008-guide-nexus-5-recovery.html
