Windows 10: Persistent & intermittent BSOD 0xc0000001 & ACPI_BIOS_ERROR

My system is a Lenovo P51s purchased around 2017. It has a hard drive ribbon connector on its motherboard, which is taken by a 512GB Crucial SSD via SATA. As you may know, this connection on this model is widely thought to be unreliable, and my system crashes unpredictably as a result. A few days ago, I've purchased a 512GB Transcend SSD in the 2242 form factor and inserted it into the vacant M.2 port, in the expectation that that connector is more reliable and will serve my boot drive, and the original Crucial SSD with the existing ribbon connector will be a data drive instead.


During the process of installing Windows 10 on it, which entails several reboots, it started giving me BSsOD marked with ACPI_BIOS_ERRORs, and I've tried to re-format the Transcend drive, rewrite its MBR, or use Windows utilities like bootsect, bcdedit, bootrec, sfc /scannow, etc. to adjust its behaviour, but none appear to have a concrete effect on this deluge of errors. I am convinced that both drives are actually functional as far as MBR is concerned, as they sometimes boot flawlessly if I leave the system off for long enough, or just keep rebooting until it somehow works. I also extensively used bootable media like a Win10 installation USB or recovery USB to probe the system, but the same ACPI_BIOS_ERROR appears even on those bootable devices. The Windows splash appears in each case before the BSOD shows up. Occasionally I'm able to coax out a 0xc0000001 error, which allows me to select things like Safe Mode, but the ACPI_BIOS_ERROR still occurs erratically and frequently.


To date I have not been able to deduce what causes the error to appear or to go away. The only thing which seems to be true is that I cannot boot from one drive, shut down, and boot from the other--that always seems to lead to an immediate ACPI_BIOS_ERROR.


I have spent not less than 20 hours over the last four days over this intractable situation. Help at this point would be tremendously appreciated to create a stable dual-drive system and render the laptop reliable.
