Hi, i recently built a new pc using these parts:

I5 4590
EVGA GTX 780 3GB
Gskill Ripjaws 1600 MHz 16 GB
EVGA 750 G2 Supernova 80+ Gold
MSI Z97 Motherboard

PC ran perfectly fine for a whole day, next day i turn on the pc and it starts doing this. I have tried an older power supply and same issue. I also tried only having the 24 pin and cpu connected and i still get the same issue. I also made sure the cpu fan was properly connected but still the computer turns off instantly. Any help would be much appreciated!
