OMEN 30L Gaming Desktop PC (AMD Ryzen 9 5900X Processor RGB Liquid Cooled, NVIDIA RTX 3090 Graphics Card, 800 Watt PSU, Windows 10 Professional, 2TB PCIe SSD + 2TB HDD, 64GB HyperX RGB RAM)

This is a very nice high end gaming desktop and we liked everything about it ...But after just over a year (16 months to be precise) the primary SSD failed. On bootup Windows 10 would give an ntsf.sys file not found error; the BIOS would detect the SSD but Windows would no longer be able to access that drive. Trying to cleanly reinstall Windows 10 from a flash drive failed as well, as that SSD drive (the C: drive) just was not recognized by the system as a valid drive.It turns out on ours the primary SSD drive is a rather obscure "pro-x-2000gb-g2r" made (or assembled) by Eluktronics, which is the outfit that assembles this PC for HP. Some component this SSD drive card must have failed, like the controller.After identifying the problem as a failed SSD, we bought a suitable quality Samsung replacement of the same exact form factor, namely a Samsung 980 PRO SSD 2TB PCIe NVMe Gen 4 Gaming M.2 Internal SSD card, https://www.amazon.com/gp/product/B08RK2SR23 . It clipped right in, in the same motherboard slot (close to the CPU and right next to the RTX graphics card) as the old one. Btw notice that this SSD is a tiny little thing !We then reinstalled Windows 10 from a flash drive, and now everything works perfectly (and incidentally the new Samsung 980 SSD is significantly faster than the old one). Success, problem fixed !It seems somebody foolishly cheaped out on one the core components, a shame really.
