How to fix PS3 Freezing problem fix: RESTORE FILE SYSTEM

How to fix Play Station 3 freezing issues. Clearing corrupted file data. Press and hold the PS3 on/off button until you hear the 3rd beep, then it shuts down. After a moment press and hold the on/off button again and wait for the double beep. A menu pops up and select number 3. RESTORE FILE SYSTEM. From there it will ask you to plug in your controller and press the PS button a few times and will take you through the file clearing and then back to your home screen.
PLEASE NOTE:
These two options (Restore File System & Rebuild Database) will not delete any content on your HDD, but it will delete all your sent and received messages as well as music playlists you have, and if you edited track information on any mp3's, say you renamed them all to something less ambiguous than "track 01", the names and other altered data will revert. (seriously, get a keyboard) For any messages you want to save, I would suggest sending them to another account you have, then send them back later.
