#NETGEAR READYNAS SOLID BLUE LIGHT HARD DISK LED 2 LIGHT UP FREE#

( I used to have this issue with my seasonic X1250 previously and had mine rma 3 x ). I believed the issue here is with the seasonic X750. I have an old alienware system that has a PSU in it but it's not modular and is connected to so many random things in that case that it would be quite a pain to get it out to check. I've never had a build fail randomly like this so I'm not sure what to do or which components to suspect.

This build is just over a year old with all new components except the 980 which was a few years older (and I've since removed it anyhow while testing) and had been running trouble free since I built it (nov 2015) I hadn't made any changes to anything lately. So how do I troubleshoot this? Is this possibly a motherboard issue? I'd assume PSU but I'm confused because obviously some power is happening since the LEDs on stuff all light up. But I would assume it would spin somewhat at start up? My PSU (Seasonic X750) fans don't spin up at all but this PSU has like a hybrid mode where supposedly the fan only spins up when it needs it. Other components in my system which have LEDs are lit (my Kraken X61 and my Grid+ V2) but the case fans don't work (and no case LEDs light up) and my GTX 980 lights don't illuminate (though I am not 100% sure if they would light up without the system being on anyhow) Opened the case and my Maximus Hero VIII's LEDs are all on but the 'START' button (which is illuminated) does nothing. When I tried to turn it on the power button did nothing. I normally leave it on and let it hibernate or whatever. I came home Friday night to my computer off.
