Windows 7: Random and frequent ntoskrnl.exe BSODs (PFN list corrupt, 0x0000004e)

09 Dec 2015   #1

Windows 7 64bit
Random and frequent ntoskrnl.exe BSODs (PFN list corrupt, 0x0000004e)

Lately I have been getting a few BSODs caused by ntoskrnl.exe. The BSODs do not seem to have any patterns; I got one when playing, another one when closing a different game and opening Facebook, or even when not using my computer (Heard it reset while being in my room).

The three I got so far this month were caused by ntoskrnl.exe+1063df. The other ones also involve ntoskrnl, but the other file is different.

My BIOS is up to date (Did it two days ago)

EDIT: I ran a Memtest86+ today and got 6 passes/ no errors.

If you need any other information, please say so!

Thank you all in advance!

Daemon tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause for BSOD's.
Please remove Daemon Tools and run the SPTD pass through remover.
  1. Uninstall Daemon Tools
  2. Download the SPTD standalone installer and follow these steps:
    • Double click the executable to open it
    • Click on the button shown below
Attachment 377802
If the button is grayed out, like in the image, there is no more SPTD installation on your system, and you can close the window

Please update the Razer mouse driver

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

Note   Note

MemTest86+ needs to be run for at least 8 passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Thank you for your answer! I have uninstalled Daemon tool and confirmed it was uninstalled. I guess this means that if I ever need to use it again, I should uninstall it as soon as I'm done with it?

As for the driver, I do not own a Razer mouse, so what driver should I update? However, I do own a keyboard, so should I look to update its driver instead?

According to the description, it is a Razer mouse driver, but if you have only a razer keyboard I would look for an update for for the keyboard yes.

So I updated Synapse, since it should update all Razer drivers automatically. Now that Daemon is uninstalled I will look out for any BSOD to see if it was the cause.
