My m.2 ssd is my only storage, and it's not working. So i don't have an operating system, or anything. I've tried putting it in another slot and re-screwing it. I don't know what else to do. But randomly one day, when I started up my computer instead of going to my desktop, it brought me to BIOS because it wasn't accessing my ssd so i didnt have windows anymore. Wtf do i do?
