Hi elliond,
You're Vaio has a hidden HDD recovery partition so as long as it has not been deleted you should be able to recover your Vaio back to the original installed OS and programs just as it was when you first used your Vaio.
To do this Start your Vaio and when you see the Vaio logo screen press F10 repeatedly this normally would start the recovery process..
If F10 fails to start the recovery process then you should be able to purchase a set of recovery disc's via Vaio support, to find contact details for Sony Vaio support..
Open Vaio support, either by clicking Support at the top of this page or use the following link:Vaio support
Under Log-in option 2: Select your VAIO model, next to Select Model Category - Select your model from the drop down list, in your case VPCW.
Then next to Select Model - select VPCW1E1R/BU
Then click Log-In
Once logged select Get In Touch.
