    New computer builder here.

    Built a desktop following closely with Carey's Fall 2016 Gaming Computer Build video (great walkthrough by the way).


    Specs:
    ASUS Z-170A
    Intel i5-6600k
    Corsair 8gb DDR4 2666mhz
    Corsair CX750 PSU
    EVGA Geforce GTX 960
    Cooler Master Hyper 212 Evo

    Worked fantastic for a year almost exactly. Then one evening the computer restarted. Rebooted. Then died. The mobo power led stayed lit but would not turn on. No fans. No post. No anything.

    I assumed power supply. Bought an EVGA 500W to troubleshoot. No change.

    After checking each component, removing all peripherals, and just trying to get a boot I finally sent the mobo back on RMA. They swapped it. I installed the new one. Used the Corsair 750 power supply. Heard a pop on power up. And now same result. No boot.

    Did I make a fatal mistake using the original PSU. Or could some other component be frying this mobo?

    Extremely frustrating.

    Did you get the exact same motherboard with the swap ? Have you tried the EVGA PSU with the new board ?

    Same board. I did afterward. Common sense says I should have attempted to use it first. Unfortunately I didn't.

    Try removing the Graphics card and connecting the monitor to the motherboard graphics connector.

    Just attempted. No post. Seems second mobo is definitely toast. Oddly still shows green power led.

    Can you do another RMA for the motherboard ?

    That's my goal.

    I'll do another inital start outside of the case with the secondary evga PSU I have, using the onboard graphics. And troubleshoot from there.

    I'm thinking it's either the PSU, bad case standoffs causing a short circuit, or the GPU.

    Sounds like a good plan.

    You should confirm the standoffs are all in the correct places first, before putting a motherboard into the case.
