ok, so seems at least to me the issues u r facing is not hardware related... Now one thing to do is secure erase ur ssd and nvme drives... i.e, restore it to factory default... Also use HHDsentinnel to check the SMART status of ur drives, u can use samsung magician... Secure erase the drives using samsung magician... Now how to do that , i wud go with rather easy but long procedure...
1)Backup your data.
2)Install samsung magician; Secure erase ur secondary SSD
3)Reinstall windows on the secondary SSD, and while doing so format ur primary drive (But always be sure to backup data to USB)
4)Install Samsung magician on new install, now secure erase the "NOW" secondary drive...
5)Check for any firmware upgrades to both drives using Samsung Magician; If so upgrade it (but save ur backup)
