See if an update is available for the Razor software, if not - uninstall it.

The latest BSOD is inconclusive.

Follow:
1. Log in as administrator, open Windows Explorer and go to C:\Windows\Minidump
2. Delete all .dmp files in that folder
3. Run Driver Verifier as follows:

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.
Driver Verifier - Enable and Disable

Driver Verifier will cause your computer to run very sluggishly - this is normal. What it is trying to do is force your system to BSOD and isolate the offending driver/s. When it does, reboot, disable driver verifier, reboot as normal, re-run the DM Log Collector, and upload the new ZIP file here.

I recommend creating a system restore point before turning on driver verifier:
System Restore Point - Create

If your system fails to boot to desktop once driver verifier is enabled, turn it off by booting into Safe Mode:
Safe Mode
