Gameplay issue

[Sylly]

I bought Amnesia from the Humble Bundle, and when I open the game, everything runs fine, except when I try to play.
I can hear everything during the intro, but cannot see anything. When Daniel stops talking, there is a black screen with a small white dot, but I can still hear everything.
I have read the other topics about the black screen and white dot issue, but they haven't helped me.
I opened and read my hpl log and my graphics card is up to date, and there are no compatibility issues that I can see.

I use Windows 7 operating system, with 64-bit. It is an Intuos laptop.
