NTOSKRNL = New Technology Operating System Kernel. Windows stops working if it does. It gets the blame for lots of things as it has many roles, one is memory management, one is dealing with driver requests. Often it gets blame for driver errors
FltMgr.sys is a “system” file used by Windows to help control various aspects of your hard drives & files. Its official name is the “Microsoft Filesystem Filter Manager” and its main duty in the operating system is make sure that the data written to the hard drive is correct and not corrupted.
Kernel security check is a driver error
Bad Pool Header is a driver error
Memory management can be drivers or Ram
is this a custom PC or brand name? If custom, what motherboard do you have? If brand, what make/model?
you might want to run http://www.memtest86.com/ on the ram and make sure its okay, you don't want to have any errors
Apart from ram, here are a few other things to try for memory management errors
If your computer is usable, but is constantly plagued with this MEMORY_MANAGEMENT BSoD, do the following:
Update your BIOS and drivers. BIOS updates can be found on your manufacturer’s website, and driver updates can either be done manually through Device Manager (use Start Search to find it)
Check for viruses with your preferred antivirus software or Malwarebytes.
Use sfc /scannow.
If on a laptop, change power settings to High Performance.
If this problem occurs shortly after installing a new program, remove that program right away.
