Question No display, no usbs connected.

Hey,

My computer isnt showing any display. I've unplugged everything and plugged it back in again, tried switching out ram, turned it on after taking components out separately but I cant seem to find the problem and its getting to me a bit. It randomly decided it would work last night for maybe 10-20 minutes before suddenly showing no display again. I turned everything off and left it like that overnight and whilst I've been at work. I come back today to find the fans are now flashing as well as the monitors not displaying anything. Can anybody help at all?

SPECS:
MOBO: MSI Z97 Gaming 9 AC
CPU : Intel i5-4690K @ 3.50GHz
RAM : Corsair Vengeance 4x4GB
GPU : MSI NVIDIA GeForce GTX 760 2GB Twin Frozr
PSU : Corsair RM750 — 750 Watt 80 PLUS Gold

Does anybody have some advice at all? My display says no signal when the pc is on but changes the message when it's off, so it must be detecting SOMETHING
