iMac 21 , OS 10.8 works very slow,

I have a computer iMac 21.5-inch, Mid 2010 , OS 10.8 works very slow, recovery over Time Machine (10.6) and a complete reinstall (10.8) does not help:

slow during the startup, even when i select OC

Bootcamp Windows 7 also not boot hangs at the entrance

What to do? I Checked the disc Macintosh HD via Disk Utility it says that the drive is OK and does not need to fix

what to do and how to find out what the problem is?

Just iWorld,

I would first go back to Disk Utilities then click on Macintosh HD and click on repair disk permissions. Once that is done I would shutdown the machine and then follow the instructions in this article: http://support.apple.com/kb/HT3964. If you are still having issues then there are a few other steps I would take. Let me know how it goes.
