Q: MacBook Pro Stuck on Apple Screen with Loading Bar! Help!!

The other day I got on my Mac and it started freezing really bad. I shut down my Mac and opened it again multiple times that night, but my Mac just kept freezing after 2-3 minutes. I shut it down for the night with hopes that it would work properly the next day.

I woke up the next morning and powered up my Mac, but it wouldn't even make it past the Apple screen with the loading bar! I left it for a few hours, but still nothing. I've tired to boot it in safe mode, but it freezes once I enter my password. I've tried to Reinstall OS X El Capitan, but it still freezes at the same spot. I've used Disk Utility to check for repairs but says everything's okay. My last resort is to whip my computer clean, but sadly I don't have a back up.   Does anyone else have any other advice for me before I give up?? Please help me!!
