Sometimes my Bolt shows a blue screen even though it continues to work normally, otherwise. (I know this because the Tivo Mini is remotely accessing it and working fine.)
I tried bypassing the Audio/Video Receiver and it still shows a blue screen. I decided to remove the Bolt from the middle shelf, remove the case, blow air to dust it off and test it for about a week uncovered, sitting out. It worked flawlessly. As soon as I placed it (cover off) back on the shelf it started acting up again.

Has anyone experienced a video adapter failing? Would temperature be an issue only for the video chip??
