Is my CPU bad?

[mostermeier]

Hello,
I am admittidly a noob. My computer quit running, I was advised to replace my power supply. It still did not work. When I disconnect the power to the CPU, it will power up. Is the CPU bad or the motherboard? Is there a way that I can tell? Thanks for in advance for any help.

Most likely the motherboard when it is between it and the CPU.

I thought so but, I was wondering if there was something I was missing. I probably could have saved the expense of a power supply if I had taken the time to ask someone. I'm off to buy a motherboard. Thanks!
