Bootcamp question: What is APPCRASH error code StackHash?

Hi,

I recently installed Windows 7 via Bootcamp but after a few days, most of startup programs or programs that I want to install get crashed with APPCRASH code of StackHash.

Is this the problem with the bootcamp drivers conflicting or something? Because I had no problem installing that Windows image on my desktop PC's.

Should we use an special Windows 7 image or something when we want to install it via bootcamp?

Does anyone know about this crash code?

Thanks.
