Hi Stupidcat,
Thank you for visiting Sony Community!
Since the unit came with Windows 8, you may try to download Vaio Care and Vaio Update for Windows 8. After installing, try to run it. It should download and install all the necessary drivers and software for your laptop.
For further assistance regarding your concern, please contact the Sony offices/Sony representative offices nearest to your place of residence in Asia Pacific region http://www.sony-asia.com/countryselector.html?hpid=countryselector:AsiaPacific. Due to proximity, they are in a better position to respond to your questions or concerns.
Regards,
Vincent
