Computer shut off randomly to black screen, won't turn on now!

[Xiphoid]

Hello! My computer specs are below:

ASUS Z170 A mobo
GTX 980 Ti Classified
Intel i7 6700k
2x 8gb Corsair Vengeance DDR4 RAM
Corsair CX750m PSU
Cooler Master Hyper 212 Evo

I was just using my computer normally, no games, just Firefox and Word open at the time, when it randomly shut off with no shut down message. When I tried to turn it on again, nothing happened, no beepor fans moving, but when I opened it up I noticed one little green light labeled PWR LED PWR SW would come on when plugged in. I've checked all my connections, and looked for possible shorts, but I couldn't find anything. I really would appreciate some help, this computer is pretty much my livelyhood! Thanks in advance!

That sounds very power-supply related. Try another PSU (Without the GPU in) if it starts you have a faulty PSU and should contact Corsair.

Remove The Card and see if you can post into bios if not I agree with Hamperking68, Most likely a PSU problem.
