So a little bit of background, my freind has been gaming on console and a 2017 macbook air I know. And for his birthday I worked with people to fund a pc build for him with a i3 9100f and a rx570 the ram and storage came from my prebuilt that I upgraded.
All was going well aside from the cheap case sucking to build in until it didn't post. So I tested the gpu and it was fine, I tested the psu, also fine then I finally checked the socket.
There was cat hair and 1 ever so slightly bent pin
I cleaned it and it runs fine now
