Q: Cannot stay logged in - El Capitan

Our mid-2010 iMac recently has developed a behavior where if any user logs in, it will accept the password, go to that user's screen, but within 10-30 seconds will grey out and return to the login screen.  There are 5 user accounts on the machine and it happens with each one.  We didn't add any software or hardware that we can think of that would have triggered this.

 

I have (1) run Disk Utility First Aid from safe mode (I can login in Safe Mode); (2) reset NVRAM; (3) attempted to remove launchservices.csstore files from the private folder.  I am running 10.11.6.  My original CDs are for Snow Leopard, which I have not attempted to use yet.  I have a 2 month old Time Machine back-up which if we had to revert to that would be ok.

 

Any suggestions on how to address this?  Or what the cost of going to the Apple Store would be?  The machine is 6 years old and works fine, but I wouldn't want to put a lot of money into fixing it vs. possibly buying a new one.  Thanks in advance.

iMac, Mac OS X (10.6.8)
