What makes you think the CPU needs repair? It could be a cable connection. The video card or RAM may need to be re-seated? It's a remote possibility but the CPU/heatsink could need to be re-seated. The PSU could be bad even if there is some power to the Mobo. The video card could have failed. There are many possibilities. I would try re-seating and cable connections to see if this helps.
