Interesting. So how exactly do I safely clean it? Where do I clean? What do I use? Thank you guys for your help. I really appreciate it.
Well I highly doubt dust and bad ventilation would be causing such a strange issue but you can use that computer duster stuff. It's basically compressed air in a can that blasts the dust out of areas you don't want dust. That stuff is usefull. Just stick the straw part of the can into the air ducts of the system and give it a few sprays.
The reason I don't think it's dust is because if dust was inhibiting the system in some way, you would probably be experiencing the same problem with all of your games.
I really recommend you call up Microsoft, It's a quick easy call and you can figure out if your Xbox is still even under warrenty. I've called on many occasions and weird problems turned out to be simple things. It's a 24 hour support line and there's no age requirement to call or anything. You'll get a voice recording that tells you which button to hit to get the help you need. Then a person comes on and you explain your probelm to them. They'll ask you a few questions and they'll decide whether it needs serviced or not. You can tell them the serial number of your Xbox, which is located on the back of the system, and they can tell you whether it's still under warrenty or not. You don't need the reciept, the box or any paper work. Just the Xbox. If it is still under warrenty they'll fix it at no cost..
