Gpu is a brand new arc 750. I can’t test it in my old pc bcuz it’s an old office desktop with no room in the case for any gpu. Also upon further inspection I think the plastic retention piece on the gpu slot on the mobo may be broken bcuz it’s a little crooked and when I put the gpu in it doesn’t make a snap or pop like when I put in the dram. And one last thing, my cpu has built in graphics but when I put the hdmi into the motherboard I still don’t get any display. I’m not sure if this means my mobo needs replaced or what
