How interesting. You say, "It's quite incredible to see the imagination of some people" but then you whip right around and say again, "If my PC smoked it would go to the repair service." Would you call the latter part of your reply another example of incredible imagination?
That aside, if your laptop did suddenly begin to emit little puffs of greenish blue smoke out through the exhaust pipes, AND then burst into a ball of flame, would you still hurdle off to the Repair Service? Also, do you believe that has never happened before?
