回答“How do I fix e74 error?”Stick to unfolded paper clips in the fans of the 360 to stop the air flow it may seem like you will mess up your console but in reality you will reflow the solder and fix it! When you boot up your xbox with the paper clips in it you will wait about ten minutes or until the single red ring turns into to red rings. Once that has happened you have to unplug everything wait like two minutes, while your over heating it ,if your watching it, the graphics may get scrambled don't worry that is perfectly normal ( it is a sign of progress actually). After it overheats unplug everything from the back including the av cable, the power cable, and the paper clips. ( don't even bother to hit the power button before unplugging it). After that you will wait the two minutes and plug in everything again (excluding paper clips) and power it up you will notice that it works now.
