Mac Mini Stuck on Apple Logo on Startup

[ugadawgs311]

My late 2012 Mac Mini is stuck on the Apple Logo upon startup. The progress bar is completely full, but nothing happens (I've waited overnight and still nothing). I also don't currently have a keyboard hooked up to the Mini, so I'm unable to start in safe mode. I've tried restarting the machine multiple times, unplugging from power, and even removing and reinstalling the RAM, but none of that has worked. Has anyone had this happen before? Any ideas on how to fix? Thanks for any help.

Bumping this as I've still not found a solution. I think my next step will be to find a wired keyboard and try starting in safemode that way. Any other ideas?
