NVME SSD can be seen in bios, then disappears.

I have a system with the specs below:

MB: MSI MAG X570 TOMAHAWK WIFI
CPU: Ryzen 7 5800x 3.8 Ghz AM4
SSD: MLD M300 1TB NVMe 2280 Gen 3x4 M.2 SSD
GPU: MSI RTX 3080 VENTUS 3X PLUS 10G
HDD: WD Blue 1TB
PSU: CORSAIR RM850X 850W

Today, I left the PC idle for a while and when I came back, the pc had gone to sleep. Mouse or keyboard did not wake it up so I restarted it and was greeted by a black screen without making it to POST. I went ahead and flashed the BIOS. Now I can make it to post and it boots straight to bios.

I disconnected the ssd, hdd, gpu and ram sticks while flashing the bios and now, after I insert them all back in I see that it boots to bios again. The problem is, my ssd is not recognised. I tried removing the sata hdd and rebooting to no avail. The interesting part is that when I reinsert the ssd, in the first boot I can see the ssd in bios but after rebooting it's gone. I switched the ssd to the other NVMe M2 slot and the same issue happened. I first see the ssd, then reboot from the bios to get to windows, then it disappears. I could not determine if the SSD or the MOBO is at fault. The hdd seems to work fine and is recognised every time it's plugged in.

I managed to initiate a nvme self test in the bios when it is recognised and the self test failed (no error code, no info. Thanks MSI)

I do not need the data since I had backed everything of value up because of some system instability issues for the last couple of weeks. No blue screens but windows updates were all jank, stuck in "updates are underway" every reboot for half an hour. Also, sometimes the GPU copy usage skyrocketed to 100% for a second or two with the pc audio and video lagging.

I suspect all these point to a MB issue but I am not sure. Any information is appreciated. I currently don't have means to test other ssd's, or test my ssd in other motherboards.

Judging from your description of the issue, this is the first thing I would try.

o I restarted it and was greeted by a black screen without making it to POST. I went ahead and flashed the BIOS.
I guess it was probably stuck at VGA or BOOT debug LED, and since you removed that M.2 SSD, you were able to POST and it boots to BIOS.
Is that latest BIOS 7C84v1C1?

I'll try and test the ssd in an external case when i get to it, but I probably won't be able to find an extra ssd right now.

I don't exactly remember the LED, but it being stuck in BOOT makes sense.

I flashed 7C84v1B as the latest non beta bios and booted to it first, then downgraded to 7C84v19 after.

I had either 7C84v15,16 or 17 at the time of the first boot failure. I only remember the release date being in 2021.
