Dell Latitude e6520 Win10 BSOD BSOD

Hello,

I have a Dell Latitude e6520 and installed have upgraded to Win10 recently. After that I did a clean install and everything was running fine up until three days ago when I got the PAGE_FAULT_IN_NONPAGED_AREA BSOD.

I have analyzed the minidump files using BlueScreenView and found the same cause of bsod in every dump file:

Bug check string: PAGE_FAULT_IN_NONPAGED_AREA

Bug check code: 0x00000050

Parameter 1: fffff6fb`400037a8

Parameter 2: 00000000`00000000

Parameter 3: 00000000`00000000

Parameter 4: 00000000`00000006

Caused by driver: ntoskrnl.exe

Caused by address: ntoskrnl.exe+142780

I ran sfc /scannow and found no problem there, I ran the system software utility tools and no disk errors turned up, as well as no memory errors using memtest. 

If anyone could offer any advice toward a solution, I would very much appreciate it.

Thank you in advance.
