One of my NF7s blew up due to a faulty DIMM slot - 512 MB of wrecked PC3200 and bits of red-hot shrapnel from the memory voltage regulator.
I was taking it apart for a post-mortem examination, and noticed that most of the places for decoupling capacitors under the CPU socket were empty.
I was just wondering if this might have been a cause for the unstable nature of this board, and the other 2 of them I have (which are also flaky).
But, there are different levels of the board, with different options - so I should expect some circuit modules to be left empty. Indeed, one my low-end boards, lots of components are missing (e.g. SATA and soundstorm).
But under the CPU, not only would I expect this to be a critical circuit, but there are adhesive residues at each component's place - suggesting that components were going to be attached, but got left off due to a manufacturing fault. In the totally unused circuits, there is not even any adhesive - why should there be if there were never going to be any components.
