Sony recovery help! [Closed]

I know there's a lot of topics like this but my Sony vaio, VPCSC does not want to start a factory recovery! I've tried pressing F8, and F10 and tried to select system restore but it asks for a disk or gives me the option to restore my computer to an earlier date which is 2 days ago! I can not get to the factory rest! The assist button doesn't do anything, even when I turn the laptop off or on!
Please help!
