Our Xbox has been freaking out lately. Rock Band said it couldn’t find the microphone or the drums, The console would hang up at various places and randomly. I found this article on support.microsoft.com that made a few suggestions. I pulled the hard drive off and noticed a lot of dust. I took the console out to the garage and blew all the dust out with the air compressor. Lot’s of dust. After putting it all back together, everything seems copasetic.
