i recently bought a new set of ram (2x4GB) that is identical to the set i already have installed but now my computer randomly restarts with a blue screen and different error codes each time. it runs fine if i only have 2 sticks in but if i put a 3rd or 4th in it crashes. i have tried every stick of ram in every slot and every possible combination. i have gotten my computer to run on each stick of ram so it doesnt seem like they are faulty. i am using an ASRock H170 Fatal1ty LGA1151 motherboard with an intel core i5 6400 Skylake 2.7GHz CPU and the ram is Kingston hyperx fury black c14 2133MHz.
