Hello, today i was playing warframe and after a few hours of playing my screen went completely black, my audio started to distort and then turned into a sort of buzzing sound. I waited for about an hour or 2 to see if anything would change but nothing happened. I finally decided to shut it off and restart my computer. Everything seemed to be working fine until i booted up warframe again. 15 minutes later i get the same problem and now after restarting it for a second time the gigabyte BIOS splash pops up and then just turns to black with a giant white horizontal bar through the middle along with some blue and green pixels on top of it. I've had this computer for over a year and im wondering if maybe the gpu is dead or what?
