Seasonic G-650 Issues?

[codyw00]

I'm trying to determine if my issue is power supply related. I have checked all my connections, checked for pinched cables and such; however the problem has continued. Occasionally when I turn on my computer it appears to boot just fine as in the fans spin up and the LED on my GTX 960 turns on. Which is good, but no splash screen nor does a windows logo appear on screen and if I proceed to hold in the power button until the system shuts off, unplug the power supply from the wall (or flip that power switch) and allow the power to drain from the power supply via the LED back lighting on my keyboard. Then turn the system back on it boots up just fine. If I just shut off the system without letting the power drain and I turn it back on the problem repeats itself over and over. This issue happens less than once a week and last happened on August 26, 2015.

try turning fast boot off.

setting ram to non xmp, stock setting 1600 or w/e

update m/b bios

run memtest86

c states or p states 

checking correct boot order.

logs might tell something. 

i tried all this and more

I have a unsolvable cool boot issue.  

its difficult to to test the psu.

I'll try the things I haven't done as I don't use fast boot, I have run memtest86 (it passed ) not sure what you meant by c states or p states, I'll check my boot order, and how would there be logs if the system isn't really started? After I have the issue windows doesn't give me a "Windows was incorrectly shutdown" sort of thing it just boots normally after I turn off the psu. Thanks though!
