If the bottom right quadrant of the ring of lights circling the power button on your Xbox is flashing, this indicates that there is a video-related problem, these lights are an indication of a hardware failure typically brought on by overheating. Too much heat coupled with poor air circulation can cause the solder joints on the CPU and GPU to warp. This disfigurement causes them to separate over time, rendering your Xbox inoperable until they are fixed. As it flashes, you see the following E74 error message: System Error, Contact Xbox Customer Support.
Don’t error messages always seem to pop up at the worst times? Like right when you get a new game, or when you’re in the middle of playing with your buddies.
