I'll start by mentioning that this whole problem began when I swapped my old Ryzen 5 2400g with a Ryzen 5 5600x. The mobo I have, Asus prime b450m-a, had an outdated BIOS version at the time, which caused a few issues. After sorting out the BIOS, I then ran into the issue of my kingston a1000 240gb M.2 NVMe ssd virtually disappearing from the computer's view, giving me a black screen and the message "reboot and select proper boot device", which is a problem because this is my boot drive. I've actually asked about this before: https://forums.tomshardware.com/threads/problem-with-m-2-nvme-ssd-after-updating-asus-bios.3744864/, but it didn't get me anywhere. A temporary solution I've discovered is to physically open my pc, remove the ssd, and reinstall it, which then allows the pc to boot properly. If the computer shuts down or restarts in ANY way, including a random restart or update in the middle of the night, I have to remove and reinstall the ssd again. I've been dealing with this for the last couple months, but now that I've had some free time, I decided I wanted to fix it permanently. So far today, I've copied the files I wanted to keep on a separate hard drive, and gone so far as going to the startup settings within the recovery tab in settings, and finding my way to the "fully clean drive" option, and following through with it. Even after doing what seems to be the most extreme option when it comes to resetting the pc, I'm still dealing with the kingston's crappy disappearing act. I'm at a complete loss at the moment, and need some help. I feel like my best bet would be to completely wipe the kingston ssd as if I had just bought it, which I thought the "fully clean" option would do, but I guess not. Any suggestions?
