Alright, heres the deal. My brand new 360 just bought at best buy on the 24th keeps giving me an E74 error message every time I turn the thing on. I got it to run once, but after that it kept giving me it. Are there any things I can do to try and fix this error message. I looked around but everything that it told me to do didn't fix it. Can someone please help me as I am really frustrated.
