    Most likely a board issue. You can try and reset the CMOS on the board, but likely will need to replace it. CPUs RARELY go bad, for the record, it can happen just extremely rare.

    A detailed description of that MSI motherboard and the processor would be helpful.

    It's possible the motherboard doesn't support the processor.

    It's also possible a BIOS update is needed before the processor can be installed.

    Another possible cause is that you are using the wrong 8 pin connector, either simply the wrong one on a wired PSU or incorrectly connected on a modular psu
    It is not easy to do so, but it can be done
    Check that you have the correct 8 pin connected and not the 8 pin GPU - graphic card connector

    All most all PSU have a CPU cable that's labeled CPU. I've not seen one that doesn't.
