It could be any number of things.

If you changed the motherboard, that means you had to remove the heat sink and processor. Did you reapply thermal compound?

And did you make sure the new motherboard accepts the same memory standard that you were using?

And did you boot into safe mode first to install the motherboard drivers?

And did you make sure the old power supply can handle the new load of the motherboard?
