Hi. Yesterday I tried to download the civilization game that was free on xbox 360 yesterday and when it started to download to my hard drive the console started to turn itself off and on. It'll stay on for a few seconds but then turn off and then the cycle repeats. I've got the xbox 360 slim and bought the 250gb hard drive for it and never had any problems until now..This only happens now if it's downloading something so I don't know if my hard drive is corrupted or if there's something else going on. It let me download a DLC just a moment ago but then when I tried to download another DLC for the same game it started doing that cycle again.
