PC doesnt turn on. 2nd time I have this problem.

[IsmaelHuico]

I built a new PC.
Specs
Core i7 6700k
Gygabyte H170 Gaming 3
Kingston HyperX Fury 16 GB (2x8) 2400 mhz
EVGA GTX 980
Corsair CX750 PSU
240 GB SSD Now Kingston
2TB HDD Seagate
Corsair Carbide Spec 02

So at first I bought a Asus Motherboard but that was the first time it gave me the no turn on problem so I gived it to a guy to check what was the problem and he told me It was the motherboard so I replaced it with the one in the Specs. The PC worked fine for 1 week until this happened.

When i re built the computer, It turned on fine but because of the Windows I installed was with the drivers of the Asus Motherboard and it didnt worked well. During this I suddenly heared the PSU fan making a lot of noise sometimes.

When I was about to reinstalling Windows, the PC didnt want to turn on again, I did the paper clip test to the PSU and it didnt worked. But after a few minutes I tried it again and the PSU worked fine. So I reinstalled Windows and installed all the drivers and everthing was fine.

After a week, it ocurred again. The PC didnt turn on. I checked everything again, made the PSU paper clip test, and it worked fine. I checked voltages from PSU, from the power pins from the motherboard and disconected everything and tried to turn it on piece by piece. But nothing.

So I dont know what to do now. I will make it to be checked again but I think it´s not normal that motherboard failures happened to me like this twice.

What do you think guys?

Could it be the switch on your computer case that's acting up? Would you have another PSU to try the system with?

I don't know, we checked voltages into the button and it had energy.
