I'm running windows 10 build 14393 on a laptop.
Some backstory: I've been getting very frequent BSODs with the error being "kernel security check failure"- about once every 2 days. I think I finally narrowed the issue down to being caused by my new usb 3 hub. I unplugged the hub and got no BSODs for about a week- at least until today.
Today I got a BSOD but instead the error was "Page Fault in nonpaged area" (a message that I've never seen on this computer before). The file concerned was cdd.dll. What could be causing this type of BSOD?
My ram is new (got it around the same time as the USB hub- 2 months ago). However, this is the first time I've gotten the page fault error message in the 2 months with the new ram, and the "kernel security check failure" errors kept occurring when I put the old ram in as a test. Memtest also completed 1 pass fine. Other than that, no hardware has been "changed" per-se, but I did open my laptop and put it back together to replace the screen which had broken.
