    So since i finished my thermal take build in march once i replaced my clogged pump, I've been running my 8700k at 5.3 at it idles around 25c and was maxing about 60c. So about a month ago I started to get some very random crashes and changed the clock to the asus auto overclocking feature which put it was a little over 5.0ghz, it was fine for about a week then i decided to put it back to stock clock. It was fine up until yesterday when i was crashing and couldn't get past the bios screen, and now I get nothing, not even any leds on the motherboard.
    So far I disconnected my extensions and used stock cables, disconnected my gpu and even used a little 300w i had around to power it, even checked if the pump was pumping normal. I was wondering if is possible if i killed the cpu, motherboard, or both? Maybe even my power supply went bad?

    What motherboard have you got? Do you have an LED poster? What voltage were you using for 5.3? 60c is extremely low and likely not max...

    The led poster isn’t even lighting up and can’t remember the volt I set it in March

    Remove the 8 pin to your CPU and see what it does. Does the system remain powered on?

    It’s more likely that your board is dead over the CPU in all honesty.

    Agree with Dutch. Even a board with a dead CPU will have power and some kind of status LED as there's a code for CPU fault. If you've got a blackout motherboard, that'll be your faulty component.

    As said above, motherboard.

    More than likely a shorted vrm stopping the board from powering up. As Dutch said disconnecting the 8pin cpu power would verify this, as it cuts power to the cpu power section the board should power on with no display, plugging it back in should stop the board from powering on. If that’s the case, it’s new motherboard time.

    Well the motherboard is dead and I put the CPU into another motherboard I bought and it worked for about 10 mins then the cpu led started to flash. So my guess is I killed them both. But this just means I have a reason to give the miss why I need to build another setup and casemod!

    That is less than a year ago...? Most hardware has three years.
