Purchased a broken 360 the other day
Fixed it with similar ways as on x-clamp-fix.com
didn't replace the thermal paste, and add those squishy things to the back of the motherboard as well. In a way this website provides a weird way of fixing the 3ROD, but it worked very well for me.
While removing x-clamp, my screwdriver "shot loose" and cutted off this little thing, from which i think is a resistor. hehe
I squished my butts together, thinking i had ruined the unit.
After having it overheat, and cool down, the 360 now works like a charm again.
However, there's something REALLY disturbing going on. The fans are horribly noisy (even when it's cold booting). And they weren't like this after i had "revived" the unit, by having it powered on with a plastic bag on top of it for about half an hour
Here's the video about it:http://www.youtube.com/watch?v=XsF0t-LpY98
Could this have happen because of the part that broke?
