Help fix BSOD with ntoskrnl.exe

First time poster. Thanks in advance for any help.

I just got a BSOD and ran WhoCrashed to see what's going on and it turns out this is the third BSOD in three months and somehow I didn't notice the other ones happen.

On Tue 1/6/2015 4:01:18 AM GMT your computer crashed
On Tue 2/10/2015 10:50:17 AM GMT your computer crashed
On Tue 3/10/2015 10:40:17 PM GMT your computer crashed

It seems really odd that all three times were almost the same date and time of each month. And I use this computer a lot so there's no chance I was only on the computer those particular days.

I haven't been able to copy or upload the dump files with access denied errors. I used the Take Ownership command on right click and it said I was successfully given permissions but I still can't do anything with them.

Here's the WhoCrashed report:

This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

  1. All three errors reference memory. I would try different memory in your system or run a memtest and see if your memory passes.
  2. Best answer
    all three errors reference memory corruption, that means the data stored in memory was not what it was expected to be.
    This can be caused by bad BIOS settings, overclocking, faulty RAM or device drivers overwriting another drivers memory block.

    normally you update BIOS or reset it to defaults, boot memtest86 to confirm the physical memory is ok.
    Then if it is ok, boot windows, start cmd.exe as an admin and run the command
    sfc.exe /scannow
    to confirm your OS files have not been corrupted.
    if you have windows 8.x and the system file checker found files it could not fix then run
    dism.exe /online /cleanup-image /restorehealth

    I would then run a malwarebytes scan. if everything looks ok, then reboot and run sfc.exe /scannow a second time
    (sometimes malware undoes fixes right after you fix them)

    if you still get problems you then would go to to your motherboard vendors website and update device drivers for you motherboard.
    if memtest86 passes, most of the time the problem will be caused by a third party driver. (assuming you use microsoft update to keep the microsoft files up to date)

    if you can not find a cause for the failure, put your current memory dump file on a server an post a link.
