If you have replaced your entire server before, and the problem persists, then I suggest you look upstream. In your position, I would be hanging instrumentation on the power lines that feed that server, looking for evidence of noise or spikes. I would make sure that, at a bare minimum, the server was receiving filtered and clamped power and, in the more likely case, the server was connected to a UPS.
I don't know your environment; it is certainly possible you have two bad servers - depends mostly on your procedures for dealing with pullouts and maintenance spares, and so forth. But were I to have that problem, I would take a hard look at the power lines.
