Question Nvme can't be recognised by BIOS or Windows

[Villas747]

I recently got a new psu, Corsair RMX650. After I installed it, windows wouldn't load. My nvme M.2 (Corsair MP510 480 GB) which contains OS, is nowhere to be found in bios and boot priority. I tried various recommendations found online, selecting different options from the bios, unplugging the sata disks from the pc, bios update, clear mos and many other. Nothings seems to work. I loaded up windows in another disk, pc works now, but still cant find the nvme drive. If it was a new drive I would consider it DOA, but it was working fine until a few hours ago, with the old psu.

Mobo: Aorus B450 Pro
CPU: R5 2600
SSD: Crucial MX 500
HDD: WD Blue 1TB
windows 10

To install Windows 10 on NVMe M.2 drive, needing to find it in bios and boot priority is not necessary. You need to have the M.2 drive as the only storage drive connected.

You create a bootable UEFI Windows 10 installation flash drive with Rufus.

Rufus - The Official Website (Download, New Releases)

Rufus is a small application that creates bootable USB drives, which can then be used to install or run Microsoft Windows, Linux or DOS. In just a few minutes, and with very few clicks, Rufus can help you run a new Operating System on your computer...

rufus.ie

You do that with the latest Windows 10 ISO. file from Microsoft.

You will need to change CSM Support in BIOS to Disabled. Boot up the flash drive. Connect the other SATA drives after installation is complete.

I don't know what your doing with, drive "which contains OS".

Thank you for your reply. I tried that, beside the Rufus program part. I did it with a bootable flash drive made with microsoft's program, having all other sata devices disconnected, still couldnt locate the m.2 drive. CSM was disabled, fast boot too.
"which contains OS" means that the m.2 drive is the one I used for my OS, until it stopped working. Sorry for any mistakes, english is not my primary language.

Now that I'm reading my post again, maybe I wasnt clear. I didnt tried a fresh windows installation after the new psu, I tried to turn on my pc as normal. An error message came up that no OS was found. When I first got the nvme a few months ago, I installed windows 10 with the other sata devices on, no problem.
