Turn off the Xbox 360. Disconnect all the peripherals, controllers and cables on the console. Remove the HD-DVD attachments, memory units, hard drives and Wi-Fi adapters.
Remove the Xbox from its present location. Place it in a well ventilated room. Do not put the console in an enclosed space; overheating is one of the leading causes of RROD.
