Ok the first question I would have is when you replaced the motherboard did you do a complete re install of the OS? You did not say what OS so I will assume Windows 7. If you did not re install the OS that would be the problem as Windows does not like motherboard transplants. I have seen Windows fail to boot when replacing a motherboard with the same make but new revision simply because some of the resources that Windows need had changed from one revision to another. I do not thing not plugging in the 8 pin CPU connecter would damage the CPU most likely it would just not boot. If the crashing started before the motherboard replacement let us know as much as you can what happened leading up to the crashing.
