Hi,
I am having the same problem with a Sony VAIO SR series. I did not install the Intel driver update on Intel's site because, like you said, it gave me a message saying that Sony has a customized driver so I should visit their site. I found the video driver updates for my model on Sony's website and installed them last night, but I am still having no luck... getting the blank/clear window.... Any other suggestions? I am running Vista.
Thanks,
Sarah
