Nvidia 770, screen won't turn on

[Chase Lendry]

I'm having a problem where my computer won't turn on with a display, the computer lights up and everything works fine. So what caused this is-- I was playing bf1 and kept crashing as soon as I started up. I read some things and it said to make sure my graphics card was not messed up, so I downloaded a graphics card tester(my card was NOT overclocked) software it ran fine for 5 minutes and then it shut off at (83C°) the computer froze up and then the screen came back on, but the computer said it had no card in it, yet I didn't change any cords and the only port to my monitor was through the card. I turned off the PC off and then tried some things and tried changing the PCI slot but nothing works. I can try to get a friend over and try and use his card, but any ideas in the mean time? Thanks in advance
