Hello everybody. A few days ago I was playing and everything looked...not fuzzy, but choppy...not sure how to describe it. A day after that I got the E74 error, and my next few tries turning it on kept turning up the E74 error. Then, something else happened, it would start up like normal, but with a blank screen. After about 30 seconds, the fan would get louder, and louder, and louder, until the xbox over heated and the fan shut off(which doesn't make sense really...that should be when the fan gets louder) and then the only thing to do was turn it off and google the problem. Would this possibly fix that? or should I get a new AV cable or something? SHould I try the RROD fix?(already done it once before a few months ago actually)
If you have replaced the X-Clamps try loosening the screws. The way I always trouble shoot this problem is the following:
1) Take the motherboard out of the metal case
2) Hook up the DVD drive and the RF / Power button board
3) Turn it on
If it doesnt give you the 2 Red Lights / Fans speeding up and turning off, then you know has something to do with loosening / tightening / mis-allignment of your x-clamp fix.
SO when you re-assemble the box, try putting the board back in to the metal case and leaving out the two middle LONG screws that attach the top plastic piece. For whatever reason this seems to help if you get a stubborn 360 that keeps doing the 2 red light thing.
Hope this helps.

I still can't seem to get this right..
Basically I am looking at two choices now...
Take a totally fracked up MB and use the Heat Gun on it until it melts or catches fire or whatever. This will show me exactly how much heat the MB can take. I know that paper burns at 451f (thanx to Ray Bradbury..
Another, less destructive option, is to pick up a Infrared Thermometer and get the chips/MB up to the required temp.. If I go this option, what would the desired temp be?? I also see reasonably priced Infrared Thermometers that measure up to 1000f. Would that be sufficient??
You will start to notice slight colorization on the solder points (goldish color), thats how I tell when its good to go. The board can take quite a bit as long as you don't get it close to the stuff that can melt / be destoryed (capacitors and plastic pieces), you really don't have to be over-cautious with it.

The chips dont have good contact with the chip dies, this can be cause by too many/few washers and too much/not enough thermal compound(size of a rice grain is perfect)
as the fans get louder it will for sure be the cpu heatsink as the cpu regulated the fanspeed.
If this doesnt fix the overheating issue you will have to do the same procedure for the GPU heatsink.
The E74 is a pretty weird error it might happen that you keep turning your 360 on and off and after like ten tries it boots up but the screen is covered by artifacts and the colors change until the screen is nearly black...
It can be caused by a faulty av-cable according to the faq but if you can see the E74 error message on the screen your av-cable will be fine.
So it will either be a pin of the scaler chip that has lost contact or a broken trace between the gpu and the ana-chip.
Just follow this tutorial it will fix it but make sure that you remove the gpu heatsink and the termal compound before doing that and that you isolate the capacitors in the area as they will blow at this high temperature.
Agreed. I wish i could edit my original post and change the heatsink thing around.
