I am surprised that the MB was replaced. Your MB does not support NVMe SSD only SATA. The specs are listed here. You will have to return that SSD and purchase a SATA M.2 SSD instead.
Hello, all. I have a Dell Vostro 3471 that I purchased earlier this year. I decided to try and replace the spinny hard drive with an SSD. I purchased a brand new WD Blue SN570 NVMe Internal SSD (M.2 form factor.) My machine isn't seeing it in the BIOS. Dell just replaced the motherboard, on the assumption that it is defective, however that did not resolve the problem. Any ideas?
