A modern video adapter is basically a processor with a specialized instruction set and multiple parallel pipelines. Video memory is not just a frame buffer, it contains code and structured data (textures, polygon lists etc.) If you're lucky, a single-bit error might just change the color of a pixel, but it might also crash the GPU.
