My 360 is being a dirty whore

[Kim]

Got my 360 out of the closet today to play Resident Evil 5, and now we are having arguments. The video and sound keeps cutting out during the first cutscene. If it were that simple, I'd suspect the cords, but the credits and subtitles are still showing. Just not the video, and I can't hear a damn thing. This is odd.

Right now, it looks like there are two possibilities.

1. I need to clean the fucking dust outta my 360. There's a lot, so I'm hoping that's it. I don't think ANYWHERE in this town sells cans of air duster, but if you guys can think of any non-standard places I might want to check, I'd appreciate it.

2. When my sibling put the 360 in the closet she banged it up or something and I'm going to have to get it repaired.

If anyone can think of any other possible causes, let me know. After I try the air duster solution, I'll probably end up calling tech support.
