I recently purchased a Dell XPS 15 9550 laptop running Windows 10 Home 64-bit. Unfortunately, every now and again I seem to encounter a BSOD.
From the debugger output, the issue looks to point to the wifi driver (nwifi.sys); however, I can't seem to reproduce the issue. The crash is very sporadic.
I have tried the following:
- Run Dell Diagnostics - no issue reported.
- Upgrading drivers - upgraded drivers on 12/01/16 including BIOS, but 11 days later, the issue has reoccurred.
NOTE: The Minidump from the crash has been attached.
Any tips/suggestions would be much appreciated.

interrupt request level (IRQL) that is too high. This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
