I have an older XBox 360 console that I've had for a few years now and it's been working great up until a while ago when I started noticing that after a bit of time playing certain games (mostly Assassin's Creed Brotherhood) that in the darker areas of the picture blue static would begin to show up and not go away. I'm haven't been able to really find any info on it. I was wondering if this is something I should ignore if my XBox is starting to hit its last legs. Any help/info is appreciated. Thanks.
