Alright so I bought a used gtx 970. I put it in the pci slot. I plug in the 8 pin. I turn my computer on and see the windows logo. Then after about 30 seconds my graphics card fans stop spinning and my monitor gets no signal. These are all symptoms of what happens when you forget to plug in the 8 pin cable. It runs for a little bit, realizes it's not getting enough power, and then turns off. I know the gpu isn't dead or fried because it outputs perfectly fine for that first 30 seconds. Can I fix this?
And by the way I know the 8 pin is in all the way. There's a little white LED that shines to tell you it's in. When it's not plugged in it's red. But that LED only detects if a cord is in there, not if the card is actually receiving power. My PSU is 750w and Asus recommends 500 for this 970 so I know it's not that. I know the motherboard and pci slot is good because if I put my 1050 ti in there (which doesn't need a 6 or 8 pin it is powered directly by pci) everything works perfectly fine. So please help me this is very frustrating.
