Sorry for the delay in reply. I've been offline.
If the SSD is no longer being detected by the BIOS, that indicates a possible physical issue with the drive or its connection interface. While system instability can sometimes be caused by software faults, losing BIOS-level recognition shifts the focus entirely to hardware.
Here are a few steps you can take:
- Make sure the SSD is properly seated in the M.2 slot and that the contacts are clean and undamaged.
- Try testing the SSD in another M.2 port or on a different system, if available.
- Check for BIOS updates for your motherboard. Some updates improve compatibility with NVMe PCIe 4.0 drives like the Kingston FURY Renegade.
- Use the "Kingston SSD Manager" to check the drive's status and apply any available firmware updates.
Feel free to ask back any questions.
