Motherboard m.2 slot
Hello everyone,
I just finished building my first gaming pc and it ran perfectly for the first week. Yesterday after work I got home and turned it on and it would not boot into windows and only boot to bios (MSI B450M Pro-VDH motherboard). After checking the bios menu it showed that my new Crucial MX500 M.2 SSD was not connected. I shut it down, removed graphics card (as the M.2 slot is just behind it) and unscrewed it and pulled it out, then replaced everything and powered it back on ( I tried this twice). Nothing still, just booted into bios and showing as nothing connected. This is weird because, just the night before I had been running the machine and playing games and now today (yesterday) would not boot? I fully powered it down the night before as I normally would any computer.
My question is this. How do I know if it's my M.2 SSD that's bad, or if it's the M.2 slot on the motherboard that is bad? Also, How would I go about erasing the data on the M.2 before returning for a refund/exchange if it's bad?
Thanks in advanced, and new member by the way

Motherboard M.2 Slot

This motherboard has the following PCI-E slots: 2 x PCIe 3.0/2.0 x16 (x16 or dual x8) 1 x PCIe 2.0 x16 (x4 mode, black) 4 x PCIe 2.0 x1.4 The PCIe 3.0 is populated by 2 R9 290 GPU's (CrossFire) So my only option is the PCIe 2.0 x16 (x4 mode, black) 2 are no issue, would this PCIe slot cripple NVMe speeds? M.2, formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the mSATA standard, which uses the PCI Express Mini Card physical card layout and connectors.

  • Both slots support Intel Optane, PCIe M.2 and SATA M.2 so they seem identical to me, and the OS should not care if it it got all the drivers. If you run into an issue, you can always put it back. I guess one of the engineer's at MSI must have had a Brainfart for putting an M.2 Slot right below the GPU.
  • If you use only PCI-e M.2 drives, then both M2ACPU and M2PSB slots can be used without affecting the SATA ports. Otherwise, having 3 M.2 slots on the motherboard where only 1 is actually usable would've been plain stupid, useless and highly inconvenient.
