Hi Mike, A machine check exception indicates a hardware problem, i.e. a broken CPU. (I am not sure whether it could indicate bad ECC memory, too. Did you run memtest68?) Since you get the problem on heavy load I would suggest to look for the CPU fan. If the CPU is overheated then this is the kind of problem I would expect. Good luck Harri
