I don’t know what happened to my hard drive but I had to replace power supply. Since then my computer hasn’t recognized my hard drive but when I put the hard drive from my computer into my moms computer it worked. Does anyone know why this would happen? I bought another hard drive to replace it but it doesn’t show up in my bios. I don’t think it could be my mother board because I replaced that too after I replaced my power supply. I’ve also tried to replace the cables and it still hasn’t worked
