Howdy,
Recently my computer had been having power issues, when it would go to sleep it would just shut off and I'd have to switch the computer off, wait a few seconds, then turn it back on and it would work fine. However, it then turned off and wouldn't turn on at all so I took the panel off the side of the case and found that the 24 pin wires had come out so I plugged them back in and turned on the computer and it started up fine but with no display.
I then took the gpu, Asus Geforce GTX 770, and started up the computer again and it started up fine. I've been reinstalling the gpu into different slots but nothing has worked. I've looked up on this site multiple things to do and none of them have worked. I should mention that when the computer boots up with the gpu installed that the display stays black. I can't get into the bios with the graphics card installed; I should also mention that computer had been running fine for 4 months before this happened.
My mobo is: Gigabyte GA-Z87X-D3H
RAM: Corsair Vengeance 8gb(2 4gb sticks)
Any help is greatly appreciated.

Aside from what you mentioned above ^^ what were the things you looked up and tried? That way we can avoid mentioning things you've already heard.

Well most people suggest making sure the gpu is properly hooked and same for power supply.
Some think these issues fall under psu can't handle (possible in itself) but I personally say that sounds like something is unstable and failing.
