Memory isn't just ram. It also includes your drives as well.
Memory management as such can be ram, hdd or drivers
PAGE_FAULT_IN_NONPAGED_AREA + NTFS.sys makes me think this is a hard drive error
PFN_LIST_CORRUPT is also the page file, which lives on your ssd I assume
only one that isn't specifically a drive is IRQL_NOT_LESS_OR_EQUAL whihc is usually a driver error but can also be caused by corrupted data
all files actually mentioned are Windows files which doesn't help me solve it
check you have latest CHipset and SATA drivers for the motherboard.
Can you copy the minidumps that are in c/windows/minidump into your documents folder and then, upload the copy from documents to a cloud server and share the link here and
someone with right software to read them will help you fix it
Dump files will show more than who crashed can.
