Q: Looping startup after downloading new OS X

I Downloaded OS X El Capitan last night. Things worked well. I shut down the computer for the night and this morning I tried start up. Start up looped by music, Apple on the screen, dark screen, shutting down and starting the process all over again. Tried safe start but it didn't work. I finally got to disk utilities and reloaded OS X. Tried restarting the computer and the same start up problems occurred. Any possible solution? Thanks!

iMac (20-inch Mid 2007), El Capitan OS

I didn't have any problem downloading it. It took an hour but downloaded just fine. My issue is trying to turn on the computer after I shut it down for the night. The loop happened when I tried to start it.
