after 30 mins or more of gametime, i exit through the dashboard on my xbox 250gb slim, the e71 error screen comes up and i really don’t know what to do. it feels like tried everything. I’ve tried unplugging all the wires and hard drive and putting it all back. I’ve given the hard drive a good shake. and I’ve cleared all my memory off of it. none of the above has helped. And I don’t feel like sending it in to Microsoft because I don’t want to spend the money. This really stresses me out!. Please help me out. it will be much appreciated. Thank you!
