Computer not shutting off

[10XTriplet]

When I shut down my computer it never shuts off. Screen goes black, hard drive still spins, CPU fan is running and case fans, but system just does not turn off. I tried pulling the CMOS battery, resetting the BIOS, I changed power supplies. Still nothing.. I'm thinking the MOBO is bad..
