I don’t know whether you have ever contacted the service center or not, but still if not then i would like to recommend you that you should visit their service center and see what they are saying about the same, because if there will be any problem with the hardware as mentioned above you’ll surely get any replacement for that particular hardware or else surely you’ll given some sort of resolution for sure. It seems like the motherboard that you have installed in your machine is recent but still some other hardware might be older, if so that it may cause problem.
