STOP 0x000000C4
DRIVER_VERIFIER_DETECTED_VIOLATION
Driver Verifier (Windows' driver-testing mode) caught a driver breaking the rules and stopped the system on purpose. If you enabled Verifier to hunt a crash — it worked: the crash data names the offender.
Likely causes, most common first
- The verified driver named in the crash has a real bug — update or remove it
How to fix it
1. Act on the verdict, then turn Verifier off easy
- Update or uninstall the driver named in the report.
- Turn Driver Verifier off so normal use isn't slowed: run verifier /reset from an admin terminal.
- If the PC crash-loops at boot: boot into Safe Mode and run verifier /reset there.
