Reset OS X Lion?

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.
If memory default, 4 GB, makes sense to add at least as much again. - clementina.Kessler38 commented on October 8th 19 at 03:03
I have a similar problem. 2010 iMac 16Gb RAM. Tormozit. The monitoring system shows nothing particularly tiraumea CPU/memory no. And as you see in the console? - Jayde.Tow commented on October 8th 19 at 03:06
Similar problem. Rolled update nachane with Show Leopard and to Lion. And asked Lion from scratch (no updates Show Leopard) and runs them much better, although the hardware is the same. - Arnulfo_Champlin commented on October 8th 19 at 03:09
From scratch of course even better time to install! - clementina.Kessler38 commented on October 8th 19 at 03:12
Bought the RAM, put the plugin banning Flash. Look at the result - addison97 commented on October 8th 19 at 03:15

Filter out all errors — enter in search bar error — read that writing system.
I'm starting to slow down just Spotlight indexing new files, or large files, or when of makromedia flash running rampant in the browser. - clementina.Kessler38 commented on October 8th 19 at 03:05

Brake system - the first sign that began to crumble the screw. Check now!
Tell me, please, what to check and how. - clementina.Kessler38 commented on October 8th 19 at 03:07
Disk check in disk utility => first aid => to check the disk.

And so of course everything is OK. I thought some non-standard way. - Arnulfo_Champlin commented on October 8th 19 at 03:13
