Windows 7: Several BSoD related to "ntoskrnl.exe"

Several BSoD related to "ntoskrnl.exe"

I buildt my own custom computer about 3 months ago, and i've kept getting bluescreens.

the bluescreens appear after i've played a medium-required game (spec wise) like Just Cause 2, or tougher games, like "Total War: Rome 2". The "tougher" graphics, the quicker i blue screen. I've installed BlueScreenViewer, and noticed that every bluescreen, even though the "titles" may be different, all relates to the file "ntoskrnl.exe".

some of the blue screens i've gotten:

Let me know if i've skipped some valueable information
I ran the latest version of Memtest, found 0 errors.
Please help me, I have no idea of what can cause these errors. I also got the newest drivers currently available for all my components, including BIOS.

Hey Erox, and welcome to Seven Forums.

Please read the instructions here: Blue Screen of Death (BSOD) Posting Instructions, and post back with the needed information. One of our BSOD experts should be by later when able to further help. :)

Hi Erox.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from, and execute the downloaded file as guided below :
  • Double click to open it.
  • Click this button only:
  • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.
Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus.
  5. Apply > OK
  6. Accept then restart.
Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.
If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

If memtest comes to be free form errors, enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Let us know the results, with the subsequent crash dumps, if any.

it "worked"

ok, so i uninstalled daemontools and deletes all the SPDTs (the button was grey), and checked every driver not from microsoft in the verifier, and rebooted.

Bluescreen while booting.

Rebooted in safemode, disabled verifier and now im back in normal mode

i think the bluescreen dump is named "112313-3681-01" (I dont know if thats even helping you hehe, you know what you're doing )

I would also like to add that i did a Memtest a couple of days ago, 9 passes with no errors.

Oh, and by the way, this forum is really helpfull, and the fact that this is free makes me feel guilty! Is it possible to donate to this website?

Try to update the driver. I am not 100% sure as I dont have the idea about the device, but may be it is the place to update the driver? Ventrilo - Download

If no feasible update is available, rebove the audio device.

Let us know how the computer is working after applying the changes.

Ok, so this is interesting-
I removed Ventrilo from my computer, and reinstalled it from their website. But when i uninstalled vent, i saw a program called "virtual audio cable", downloaded the 10th of august (right when the bluescreens began i believe) so i uninstalled that aswell.

i rebooted my computer with verifier enabled just as last time. I did not bluescreen at bootup, i logged into my windows user. I was on the desktop for about 3-5 seconds before i bluescreened. (i pressed the google chrome-shortcut right before it happened).

I'll give you the new dump files

The Zip does not contain anuthing new after the dumps of post #4.

Disable verifier now and run the computer normally. Let us know how it is working. Report about any further crash. If needed, later we will enable verifier again.

Follow it: Dump Files - Configure Windows to Create on BSOD
Go to Option Two, Point 2. Download the .reg file and merge it in registry by double clicking it.

Now wait for another BSOD. When it occurred, search the .dmp files manually in the default path: C:\Windows\Minidump or %SystemRoot%\Minidump. See if the crash dump is recorded or not (hopefully it will be recorded).Post it following the Blue Screen of Death (BSOD) Posting Instructions.

Also try to take a camera snap of the bluescreen. May be the code can give some idea.
