iMac freezes everyday

My iMac has been freezing, or locking up, more in more frequently over the past 6-12 mos. It essentially happens at least 1x per day now. Is my hard drive about to die?

I saw a message on another thread that mentions an EtreCheck report. So, I ran this, and have included the output for anyone that knows how to diagnose the report.
