Hi, for about two weeks my PC is sometimes having problems turning on,
When i press the power button, sometimes it turns on right away, and sometimes it doesn't, eventually it turns on after 10 sec or so,
sometimes it doesn't turn on at all so i place the switch at the back of the psu in a position between on and off and the pc starts right away.
The motherboard LEDs are on and if the computer turns on, i encounter no problem at all,
I checked the voltages in the BIOS and the values are good.

My system is around 1.5 years old except the PSU which is 6 months
Specifications :
- PSU : Coolermaster v1200
- GPU : Sapphire 390x
- CPU : I5 4690k
- Cooler : NZXT Kraken x61
- RAM : Gskill ripjaws 8go ddr3 1600mhz
+ Adata xpg 16go ddr3 1886mhz
- HDD : western digital blue 1to 7200rpm
- Motherboard : Asus maximus vii ranger

Thanks in advance and sorry for my bad English

Thanks for the answer.
I checked the power outlet, cables and all but unfortunately the problem isn't there.
I also checked the Ram, tried with only one barrette, changed the Slot and still the same problem.

so i tested with a different power supply and no problem at all,
can i conclude that the psu has problems or there may be compatibility issue or something else to check.
i found i user on reddit who has a somehow similar problem to mine, link : https://www.reddit.com/r/pcmasterrace/comments/3v8u9g/pc_not_turning_on_sometimes_with_cooler_master/
