So I thought my 360 was starting to die. Wireless controllers wouldn't sync to the system, and the HD-DVD drive wouldn't work when plugged into the back USB port. Calling MS, I had disconnected everything to get the serial number. After describing the issues, she had me do some testing, then asked if I was plugging this directly to a wall socket or using a surge protector. I was definitely using a surge protector, and her explanation made sense why this can be a problem. The 360 power brick has surge protection built in, and connecting it to a power strip or protector can cause power fluctations (as the strip routes power to multiple devices). Everything works fine now, and I was certainly releived. So what does everyone else have their 360 connected to? Wall, Strip, or Protector?
