Question No monitor signal after installing new M.2 NVMe SSD ?

Jul 6, 2022
So I recently decided to add a M.2 NVMe SSD to my pc as an upgrade, but now I can't get any signal to my monitor with it in. When I remove the M.2 SSD everything works as before.

Fixes I've tried:
  • Changing my SATA ports to all ports that aren't disabled with an m.2
  • Reseating RAM, GPU, motherboard battery, all motherboard connections
  • Checked my GPU was in the correct pcie slot
  • Checked new m.2 is compatible with my system

Things I've yet to try is updating my BIOS (nothing on the updates mention anything about ssd compatibility)
I also saw something in the BIOS about splitting PCIe lanes from 1x16 to 4x4x4x4 but would rather not do this as I think I would lose performance?

System Specs
MSI Tomahawk b450
Ryzen 5 2600
16gb Corsair Vengeance
GTX 1660
Corsair TX550w
500gb SATA SSD
1tb HDD

The M.2 SSD I'm having trouble with is the WD SN570

What BIOS version are you currently on for your motherboard? Often times, the first thing to do that usually solves compatibility issues is to make sure you're on the latest BIOS version. As for your SATA ports being disabled, just make sure you've got no SATA device plugged into SATA ports 5 and 6.

How old is the PSU in your build?
