E68: Voltage Error... This error means that the Xbox 360 has insufficent power to function properly. This can be caused by an error in the hard drive or the fans that make them suck up too much power, it can also be caused if you have unnecessary accessories attached to the console like an external fan unit. Attempt to remove unnecessary accessories first, and then necessary components such as the hard drive and USB devices. If you have any case mods you may want to investigate those as well.
