I've had this 360 for almost 3 years now, and now it starting shutting off every 20 minutes, if i'm lucky. The power cord light turns red, so i un-plug every cord, and then plug it all back in, then it turns orange (Green when on) but it still shuts off after 20 minutes. For the past 3 or so months the power cord has been making loud noises, but since this issue started it doesn't make a sound, so i assume the fan broke. But i put a small fan in front of it and it still shuts off. Please help.
