I had the same problem. First i get Yellow, then three beeps then flashing red.I followed the guide. The fan runs quietly and air that comes out of the back is not too hot . It worked wonderfully, for about an hour. Then it bricked. I let it cool then run it again, same thing, it YLODed . After cooling it for The 3rd time it was a minute or running then YLOD.
My model is CECHG01.
