This just started happening in the last month or so and now it happens almost every time I try to shutdown my 360. I can push the power button and it turns off the video, but the xbox stays on and the power light blinks until I unplug the power from the console. I've tried shutting down via the miniblades and the same thing happens. Is there a setting in dashlaunch or something that I've overlooked that causes my xbox to refuse to shutdown? I have a jasper bb 256 RGH1, it runs great except for the shutdown issue.
