Your problem sounds like a Graphic Card issues. Your probably best to go to the Sony Vaio forums and search for similar issues with games. They is generally a thread in those forums dedicated to issues with graphics and gaming.

The usual advice they give is to update windows, download the latest drivers for everything (including direct X).

Without knowing the specific spec of your computer its difficult to say, but in the past I have had to reduce the graphics hardware acceleration in windows to solve this kind of problem.
