Turn on your PS3 system and enter the XMB menu. You can do this by removing whatever game or movie is currently in the disc tray.
Select "Settings" and then scroll down to "System Update." Press "X" to open the menu.
Click "Update via Internet."
Wait while the PS3 searches the network for the most recent firmware software. If new software is detected, you will receive a message that states "The latest update data was found."
Press the "X" button on your PS3 controller to begin the automatic firmware update. This will resolve any problems with old firmware.
