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.
