Changing PC Case/Intel Heatsink CPU Fans Spin For Half A Second Before Turning Off

I have recently just moved all my PC components into the NZXT H440 from my old crappy case. The old PC ran without a problem and booted every time but the cables were a mess and it needed to be sorted out properly, So i decided to change to a new PC case. I took out all of the components and I did it without a problem. When i started putting things in the new case I managed to get the motherboard in with a bit of a struggle getting it into the right place but i think i got it in the end. The board is not touching the case and everything is plugged in accordingly. When I had put it all together and turned it on for the first time the CPU fan started spinning for around a second and then went of. The case fans and LED lights didn't turn on either. I haven't got it to boot at all and I am really unsure on what the problem is. The only good thing that I got from it was when i stepped back and looked at it it looked really good!

Here Are The Specs

Intel I5 4690K 3.5Ghz
Geforce GTX 1080 Founders Edition
8GB DDR3 RAM
Gigabyte Motherboard ( Not sure what the exact name is)
600W Corsair PSU

Like i said the PC ran just fine in the old case without a problem so I know its nothing to do with bottlenecking or anything like that.

Thanks

    It honestly does sound like a loose connection if you've gone from completely normal working function, and just moved cases.

    I know you say you've checked everything but I would recheck again. Ensure absolutely everything is connected correctly, including front panel connections, equally remove the RAM / GPU and ensure that the connections are clean and free from dust/debris (extra attention to the CPU power pin). Once again, double check that there is nothing shorting the motherboard.

    If necessary, build your PC up one by one. Start with just the PSU, MB, CPU, HSF. Then see if power stays on. Then seat a single RAM module and see if you can boot normally, and so on.

    It sooner sounds like a connection has come loose or plugged in incorrectly (with all due respect). It can easily happen. So I hope it is as simple as that too!

  2. I'd go with checking the cables from the from the PSU to the MB and CPU. And use a the motherboard power button/pins to rule out that's case button that is stuck. Some brand new cases I've built have had "sticky" buttons because they're brand new.

    I had a similar experience with the CPU spinning for only about a second or so. After reading many suggestions I finally tried changing the CPU fan, and "walla" it started working normally again with no further problems. Might be worth a try for any one with this problem.
