So I've been helping a friend with his pc for about 2 or 3 weeks now. We were doing a upgrade using some old parts but also using new parts. I built his computer, was able to install windows and got everything setup. No problems on desktop or anything. I got home and wanted to play a game with him, he installed pubg and we started to play, everything was running well until about 5 mins later he gets a blue screen and his computer restarts. So he turned it back on and now he can't even get past the bios screen. And I came back over several times trying to fix it and I have no idea what the problem is. I took the pc to my technical school and had my teacher look at it and he thinks it's the video card. But could it also be a motherboard issue or anything else? The stop code for the blue screen was iqrl not less or equal
