By the way, somebody above said that this may have been caused by an improper video driver installation. Note that my problem appears even after a fresh RECOVERY install using Sony's CD. Now, I tried to uninstall Sony's Nvidia driver, clean using Driver Cleaner Pro per instructions, and then reinstall Nvidia Forceware. Same problem. So if anyone else having the same problem as mine, please let me know.
