Help Blender Crashes!

After reinstalling windows my mouse pointer flickers in blender and it crashes when I try to use a video as a background image. help because its slowing me down. thanks.

Does this happen with any video file? I think this could be caused by the video’s particular codec.

Thanks. it doesnt happen with all videos. I will reinstall my codecs then post the results.

If not that you did just reinstall windows - Might mean you need to get the latest drivers for your video card again.

Thanks guys. I disabled shadows on my mouse pointer and the flickering stopped. also reinstalled my video drivers and the crashes stopped. happy blending.
