Windows 7: BSOD Complete sporadic, not triggered by intensive use. ntoskrnl.exe

15 Feb 2015   #1

Windows 7 Ultimate 64
BSOD Complete sporadic, not triggered by intensive use. ntoskrnl.exe

Hello, I am hoping I could please get help with my problem. I am having completely random BSOD, its sporadic and does not seem to be triggered by specific events. I have had periods of complete stability, and then Ill have periods where It crashed 3 or 4 times a day. I have not made any Hardware changes. Ive tried fresh install, 8 passes of memtest86 (no errors), chkdsk /r, and it has been no help.

I have tried using a viewing to diagnose, and get the following info:

Caused by Driver: ntoskrnl.exe (but i know this could mean anything)
Bug check codes:

I am uploading my latest mini dump files.

I hope someone can help me with this... Im about to buy a new system.

Best regards,

Versatile BSODs with nothing precise, but there is always a hint of display failure.

Install the latest WHQL display driver only.
  • Uninstall All nvidia items in Control Panel > Programs and features
    • 3D Vision Control Driver
    • 3D Vision Driver
    • Graphics Driver
    • HD Audio Driver
    • PhysX
    • nvidia Update
    • GeForce Exoerience
    (Are you using nvidia chipset drivers? If so, dont uninstall anything other than those are listed).
  • Now follow Drivers - Clean Left over Files after Uninstalling
  • Go to Drivers - Download NVIDIA Drivers, Download and install the latest WHQL. While installing, Select Custom (Advanced) install. In the next page, follow this settings:

That is, install the Display Driver and the PhysX only.

Also, such a versatile BSOD is a close indication of a failing hardware, sometimes. Take some hardware tests as well.

► Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest86+ for at least 8 consecutive passes.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

► Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark
Take a screenshot of the furmark window before closing it. Upload the screenshot for us.

► Stress test the CPU.
Hardware - Stress Test With Prime95
It saves the result as a .txt file in the prime95's folder. Upload the file for us.

► Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy. Alternatively, you can publish a Speccy snapshot too: Speccy - Publish Snapshot of your System Specs .

Let us know the results.
