I do not agree with your point that it may be hardware. Symptoms we are seeing are too random to consider it as hardware issue. Also, as you can see almost 40% of the entire users just on this forum do not experience any issue at all. Considering that people on the forum are more active and vocal than general public, I would say more than half of GN users probably would not be experiencing the issue at this moment. If the problem is going to be anything about hardware, it should be more reproducible, by anyone, at anytime.
