I've been having this issue for quite a while now. I install Windows 10 on my m.2 SSD, and after about 2 hours or so, I get a BSOD - Critical_Process_Error. I've been on forums, contacted Dell (they replaced the MOBO, RAM, and m.2), I've installed and reinstalled multiple times (in Legacy mode and UEFI mode), but I keep getting the same issue. I even took the battery out and ran on the adapter, changed the RAM again, ran a memtest, and even bought another new m.2. I'm sure it's a Windows problem because I installed Windows on a regular SATA SSD and it ran for days without issue. So if I could get some other brains out there to take a look at this I think it would be a huge help.
