So my pc in the past ended up just going black, it'd turn on and fans would go but the screen remained black "on all monitors/hdmi" so I took it to a repair shop "A+ computers" a small business, they took several weeks but ended up figuring out the graphics card was the issue, got a new one and boom I could see things. But very soon after I started realizing issues again, ranging from hissing to popping to my pc completely freezing. The hissing seems to have slowly gone away but recently it started getting worse in the matter of I get screen tearing no matter what I'm doing and constant stutters "no matter the hertz" and then just yesterday my pc turned black for a second "all but reminding me of the former issue" and I thought this wasn't serious and wouldn't happen again but nonetheless I turned my pc off and ignored it for 10 or so hours. That's all fine but when I woke up the next day "today" I got on did a few things and after about an hour my screen went black again, now I only fear that my gpu is dying again and the issue that I hoped was fixed is all but back. So my real question isn't only is this a gpu issue it's is something killing it? Like maybe the PSU is killing it or maybe even the cords.
