you have a memory related error on CPU 0, most likely a ram module is failing/has failed or a bad module connection try reseating the ram, and then run a memory test like "memtest 86+"  (the "+"plus is important) google for a DL site

Miguel, try as DGroves said.  It is a loose connection :  motherboard X riser-board    either   ram memories X riser-board .

DO NOT TOUCH WHILE  UNDER VOLTAGE !

After disconnect from wall outlet, keep pressed the Power Button for few seconds to discharge of remaining harmful thing in your PSU.

i was very specific to state that the ram for CPU-0 was the source of the problem based on the error message and that reseating the cpu-0 ram modules or swapping them would either resolve the issue or point to which module was failing
