Became very slow Mac, extra programs, rather modest range available. Err on OS X Lion (because iron is normal, iMac 2011). Free disk space full GB 700. Consider the bare minimum. How do I reset the OS to "software set when originally purchased, but stored personal data (My files, Downloads, Documents, etc)"? Thank you.

For starters boot from the system repair disc, sign in to disk utility and restore the rights. Then console and monitor the system to see what slows down the system — how that eats away CPU time or memory...
If you still decide to reset the system to its original state, you'll have to reinstall from scratch. Copy personal data to external media and reinstall the system. To certainly not traces of the old system, before installing, in disk utility erase a large section.

Filter out all errors — enter in search bar error — read that writing system.
