I just installed new NH-D15 CPU cooler and my computer is only starting for 2-3 sec. Fans start like normal but only for 2-3 s

Solution
all power plugs like the atx12v connector in place? 8 pins

check the motherboard's CPU socket if pins are bent.

any beeps? or led debug code?

I double checked every connector is in place where they should be. I have green led light burning on MOBO and graphics card which I have had when my computer booted normally

I had wrong connection at my eatx12v connector and that was the problem, now working fine with this new cpu cooler. Thanks for your help, you pointed me to right direction :)

There was for some reason 6 pin instead of 8 pin, I think i had missed it somehow when I installed new power supply. I had googled that 6 pin is enough but it needed that 8 pin :D so it was pure human error

Thank you for your help
