Random BSOD, nvlddmkm.sys identified by driver verifier

Hi there, I've recently been getting random BSOD events, 8 so far, showing 5 different causes, (ndis.sys / ntoskrnl.exe (x3) / Rt64win7.sys / cdd.dll )
I've ran memtest on all 4 sticks of ram with no errors and ran the machine with driver verifier on.
this is when i got 2 BSOD within a few minutes of each other, both pointing to nvlddmkm.sys+9b0a1.
i have the latest drivers installed from nvidia for the graphics card (and had them installed at the time of the last two BSOD)

should i try an older video card driver?

any help would be greatly appreciated.

Edit: BSOD last night again, win32k.sys this time

Attachment 306899

I've uninstalled all nvidia drivers, cleaned using the DDU tool and installed 334.89 driver. i'll see how it goes.

also noticed my processor has been running at 3.69GHz so ive disabled intel turbo boost to bring it back down to 2.79GHz. not sure if this will do anything at all but im willing to try it out.

McAfee is vicious. It is most frequent BSOD causer. Uninstall McAfee Using McAfee Removal Tool. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one, for a safety reason only; as the installed antivirus is failing.

Let us know for any further BSODs.

Upload the list of all the third party drivers Using NirSoft DriverView :

• Download and execute Driverview
• View > Hide Microsoft Drivers
• Edit > Select all
• File > Save Selected Items
• In the Save dialog, Set the path to desktop, Put "Driverview" in the name field, and save.
• Zip the .txt file and upload it.

Uninstall Intel Extreme Tuning Utility. But before uninstalling it, run it and set everything to default.

Uninstall Virtual Clone Drive.

Update Intel USB3 drivers for Clevo p170sm .... I have no idea about the download location for the model unfortunately, so cannot guide you in it.

And, Disable USB Selective Suspense too.
USB Selective Suspend - Turn On or Off

Let us know the results.

Hi ATAS.

Apparently your issue is not caused for overclocking (it will remain stable over a few more months, IMHO). So it is not a must to pay the utmost attention on it right now. Intel Extreme Tuning is contributing to the issue otherwise.

You can disable those overclocks anytime by booting into the BIOS. And that is the right way to do it, other than using any program.
