I don't know that you will be able to get to the bottom of that problem. Multilayer boards like those found in PCs, which have pressure-sensitve intermittent problems, are often suffering from either bad thru' plated holes, or badly flowed solder under BGA chips. You might be able to get closer to the problem by careful probing with something like a ball point pen, but failing that turning up anything easily spot-able or fixable, you're probably going to be on a loser. What is much more interesting, is that your attached picture has gotten through. I wasn't aware that this group was set up to accept picture attachments. I'm sure that people have tried before, but always finish up having to post pictures and illustrations, on third party websites. Am I wrong on this, or has something changed recently ?
