Me and my friend built my first computer. The specs are as shown:
Asus Strix gtx 970
intel core i5 4690k
corsair vengeance 8gb ram
gigabyte z97x-sli mobo
CX750w PSU


When we turn it on, the graphics card light turns on, and the fans start spinning, when we go to the video output of the tv(hdmi) we see the mouse on the screen for about 2 seconds and then it disappears and nothing else is shown. I believe it's getting past POST and something is just causing it to short? Any help is appreciated.
