Hardware Problem: Constant BSOD / "Kernel Security Check Failure" in UE4

Development Platform & Builds

I decided to splurge a bit on a new laptop, for the sole purpose of being able to nicely run UE4. But sadly, it’s been a complete mess. UE4 often gets the BSOD upon boot up, or randomly while using it. The BSOD Windows 10 window says “Kernel Security Check Failure”.

I’ve gone through as much stuff as I can find online to try to remedy the problem with no luck, but does any one know if anything about my computer is just incompatible with UE4? Or anything else I can try? Specs:

  • Alienware i7
  • Intel(R) Core™ i7-6700HQ (Quad-Core, 6MB Cache, up to 3.5GHz w/ Turbo Boost)
  • NVIDIA(R) GeForce(R) GTX 970M with 3GB GDDR5
  • 128GB M.2 SATA 6Gb/s SSD (Boot) + 1TB 7200RPM SATA 6Gb/s (Storage)
  • Windows 10 Home (64bit) English

Thank you!

Hi JSpaceman,

I’ve done some research and it looks like this BSOD error seems to come up when your PC isn’t switching to the discrete graphics card(the GTX 970M) when running a GPU heavy program. Most laptops with a discrete card still have an integrated card and switch from integrated to discrete graphics cards on the fly to save battery.

These settings can be found in the Nvidia Control Panel under 3D Settings>Manage 3D Settings>Program Settings. You’ll probably want to set UE4Editor.exe to use “High Performance NVIDIA processor”, but you should be OK leaving the Epic Games Launcher on the integrated card. If it continues though, change it for the Epic Games Launcher too.

Hi ,
I’m sorry to report that though this fix seemed to help (I didn’t get BSOD for about 4 days), I got it twice in a row while using UE4 yesterday, and I’m still having numerous crashes. Sometimes it’ll crash 3-4 times in a row just on boot up. Some times it’ll go hours and be fine, but other times it crashes over and over and over.

I’ve been submitting a lot of my crash reports, but I wondered if you might know of anything else I can try? Does this seem like a hardware issue to you?

Thanks again,

Can you send me the callstack that you’re seeing? The crash reports are anonymous and I’d like to track them down.

Preferably copy it into a txt file and attach here.

Also, did you upgrade your PC to Win 10 or did it ship with it? If upgrading, you’ll need to get Alienware’s specific drivers for Win10, not the generics from Nvidia.

Thanks again, !

Here are four crash logs. Hopefully I did this right. The last one is actually a launcher crash, I don’t get that one very often, but figured I’d go ahead and attach it. I often get UE4 crashes upon launch, and of course randomly in the middle of using it. I’ve also since gotten two new BSOD errors, but one happened when UE4 wasn’t open. Thanks again!

Hey JSpaceman,

I don’t know why I didn’t ask before, but could you tell me your nvidia driver version? I’d also like to note that when looking for drivers to your laptop, I’d look on the Alienware website for Win10 specific drivers to that laptop.
