I built this PC like early 2021. Everything worked flawless until few days ago, I actually don't mess with PC anymore like don't even play videogames anymore due to my cornea injury, so I usually just use it to do light browsing and office work. So I've never mess with settings anymore. then about a week ago it just stop booting.

First it didn't give any signal to my Monitor, so I thought my GPU died. But after few reboot, I was able to enter BIOS, and it shows it recognize my NVME SSD (Which is my only boot/storage device. I don't use SATA.), so I don't think there shouldn't be any error about boot sequence.

But then it doesn't boot. It keep goes to Bios and if I for boot with my NVME, it gives message "Can't find proper boot devices. "
It's also my first NVME build, no HDD or SSD. so I didn't know where to start... There is no unplug/plug into other SATA port solution. lol.

Then I went to use Windows Repair function with USB stick, then it doesn't work either.

I have some important files, so I was trying to save data at least. I hooked my old SATA SSD, and booted Windows, and try to access my NVME drive, then it denies access (Even I changed the setting to give permission to access my NVME)
What could be the problem? Is this something I need to send it to Samsung? Could it be defective hardware? I don't know why everything was working fine for a year, then suddenly it just committed seppuku.
I heard Samsung makes the most reliable SSD so I always bought Samsung Product (Especailly after going through crap fest with my first SSD... TOSHIBA SSD.)
Thank you before any replies.
