I've been having this problem with my custom built PC for about 2 months now. My computer is about a year old and does work fine, but every single day it just refuses to start up unless I hold down the power button and wait for a flashing blue light on the mobo to go away, after doing this I press the power button again and it sometimes starts up. If it doesn't start up I unplug the PSU for a bit and plug it back in and do it again.
I'm not sure what the problem is, when my PC turns on, it runs really well and I have not notice any problems while it's on. When I shut my PC off, it doesn't power back on unless I do the same thing to turn it back on again.
Here are my specs
OS: Windows 10 64 bit
CPU: i7 4790K
Mobo: MSI z97 Gaming 5
GPU: NVIDIA GeForce GTX 970
RAM: 16GB Corsair Vengeance Pro Series DDR3 DRAM 1866MHz
