The problem with randomly replacing various components, other than the downtime and nuisance, is that there's no way to know that the change actually fixed any problem. When the base rate is one unknown system hang every few weeks, how many wees should I wait without a failure to conclude that the replaced component was the cause? A failure which happens infrequently isn't really amenable to a random diagnostic approach.
So you pitch the whole thing over to being a test rig, and buy all new hardware?
