Try to find a different monitor to hook up, and see if it does the same thing. If it acts normal, problem is your monitor. If it does the same thing, next suspicion should fall on your video card as being faulty.

Sony Vaio...Sony makes great computers, however, they are incredibly proprietary. I would go to the Sony website, and check for any video card driver updates they might have. Also, are you running a Sony monitor? You possibly might want to check the monitor properties, and see if you can install exactly the same kind of monitor you have, and not just a generic plug and play monitor.
