Just as your quote says: You sometimes have to use google to find out a fix... It needs to be reflowed or sent back to MS.
A reflow re-melts the solder on the GPU, CPU & RAM chips. There are a few ways of doing this, the best by far is to find someone with a proper reflow stations or You can do it with a heatgun also (just not as effective). Do a search as ben420 suggests, or you could just scroll down this forum as there as 2 threads on this on the front page.
