Serenum.sys Ntfs.sys BSOD + Minidumps

[justlearning]

This has been going on for a few weeks now. It does not happen often. I have absolutely no idea what to do about this but have prepared a few minidump files to help with the process. The last BSOD seems to be caused by serenum.sys but the one before it was caused by ntfs.sys

Last night during a Malware Bytes scan I woke up to a BSOD caused by Intelppm.sys. What is going on?
