How I Fix Error E74 on My Xbox 360 (if Nothing Works)

 This is not a full detail tutorial, but I wanted to show you how I fix my Xbox 360. When I got the E74 for the first time I tried to find tutorial how to fix it and what it was. First , it's a overheat from the graphic card. Normal when you see the heat sink they put on it. Anyway I try so many modification, Like add 2 fan close to the heat sink, change the thermal past, add little disk under mother board, heat motherboard with a heat gun, etc...But every time it works only for 2 week and bang , come back again. So I decided to do that big modification, I know that suck, because It's look like a space craft..but I don't have to buy a new one and that still working after 10 month.

Sorry for the writing I am franco :-)

This is what I put on the GPU (Graphic processor unit) It's a mega big heat sink than I take from a Dell computer. I am pretty sure you don't have to put one that big to fix it, but I take no chance and I use the bigger than I have. I also add a fan on it witch is again not really necessary because this heat sink always stay cold but it's already done so I left it there. So I take the 12 Volt for the fan on the motherboard. I you want to do that just google : 12 volt on motherboard xbox 360 and you will find it. Just verify witch model of mother board you have.    

 I build 2 peace of metal on each side to old it in place. Before putting in place the heat sink you have to clean the GPU and put a little bit of new thermal paste. I bought one on ebay, witch is the best one on the market for 9,99. It's a silver one, lot better than the one you will find at Radio shack. And don't tight to much the screw.

 Because the DVD reader is normally over the heat sink you need to change the place of it. So I cut a peace of cardboard and put it under. Use zap strap to old it in place. And Use a little wood stick and a straw to be able to use the eject button again. Of course I cut the front panel in 2 parts.

 I just build up a template first with some piece of paper and after that draw it on a big white one and cut it. And that it.

Thanks for watching. I hope that will help.
