Question about Microsoft Xbox Console
That my friend is an AV issue that lies between the HANA chip and the GPU. It can be either of the two. Personally, I flux and re-flow both chips by hot air and then x-clamp mod the heatsink. Be careful with this method, because damage can be caused to the chips when temperatures get too high. There are several online tutorials for this. On the other hand the X-clamp might work alone, but since that is more of a temp fix alone I would go the other route with hot air or get someone to fix it for you. I hope this helps.

Tips for a great answer:
E74 is due to an inherent
engineering flaw and will continue on new consoles until Microsoft institutes a
E 74, E 79, E 71 is shown
on screen and a solution to fix it is by ensuring that your A/V connections on
your Xbox 360 is secured. Another possible cause to the error is that there is
a power surge or outage on your system.
