How Do I Stop DPC Watchdog Violation Blue Screen?

I could have sworn I responded to this thread... huh...

Anyway!

All of the recent DMP files are of the DPC_WATCHDOG_VIOLATION (133) bug check as we've seen.

This bug check indicates that the DPC watchdog executed, either because it detected a single long-running deferred procedure call (DPC), or because the system spent a prolonged time at an interrupt request level (IRQL) of DISPATCH_LEVEL or above.

This is looking to be a hardware issue, but can you please enable Driver Verifier to be sure?

Driver Verifier:

What is Driver Verifier?

Driver Verifier is included in Windows 8/8.1, 7, Windows Server 2008 R2, Windows Vista, Windows Server 2008, Windows 2000, Windows XP, and Windows Server 2003 to promote stability and reliability; you can use this tool to troubleshoot driver issues. Windows kernel-mode components can cause system corruption or system failures as a result of an improperly written driver, such as an earlier version of a Windows Driver Model (WDM) driver.

Essentially, if there's a 3rd party driver believed to be at issue, enabling Driver Verifier will help flush out the rogue driver if it detects a violation.

Before enabling Driver Verifier, it is recommended to create a System Restore Point:

Vista - START | type rstrui - create a restore point

Windows 7 - START | type create | select "Create a Restore Point"

Windows 8 - http://www.eightforums.com/tutorials/4690-restore-point-create-windows-8-a.html

How to enable Driver Verifier:

Start > type "verifier" without the quotes > Select the following options -

1. Select - "Create custom settings (for code developers)"

2. Select - "Select individual settings from a full list"

3. Check the following boxes -

• Special Pool
• Pool Tracking
• Force IRQL Checking
• Deadlock Detection
• Security Checks (Windows 7 & 8)
• DDI compliance checking (Windows 8)
• Miscellaneous Checks

4. Select  - "Select driver names from a list"

5. Click on the "Provider" tab. This will sort all of the drivers by the provider.

6. Check EVERY box that is NOT provided by Microsoft / Microsoft Corporation.

7. Click on Finish.

8. Restart.

Important information regarding Driver Verifier:

• If Driver Verifier finds a violation, the system will BSOD. To expand on this a bit more for the interested, specifically what Driver Verifier actually does is it looks for any driver making illegal function calls. When and/if this happens, system corruption occurs if allowed to continue. When Driver Verifier is enabled, it is monitoring all 3rd party drivers (as we have it set that way) and when it catches a driver attempting to do this, it will quickly flag that driver as being a troublemaker, and bring down the system safely before any corruption can occur.
• After enabling Driver Verifier and restarting the system, depending on the culprit, if for example the driver is on start-up, you may not be able to get back into normal Windows because Driver Verifier will detect it in violation almost straight away, and as stated above, that will cause / force a BSOD.

If this happens, do not panic, do the following:

• Boot into Safe Mode by repeatedly tapping the F8 key during boot-up.
• Once in Safe Mode - Start > Search > type "cmd" without the quotes.
• To turn off Driver Verifier, type in cmd "verifier /reset" without the quotes.

・    Restart and boot into normal Windows.

If your OS became corrupt or you cannot boot into Windows after disabling verifier via Safe Mode:

• Boot into Safe Mode by repeatedly tapping the F8 key during boot-up.
• Once in Safe Mode - Start > type "system restore" without the quotes.
• Choose the restore point you created earlier.

How long should I keep Driver Verifier enabled for?

I recommend keeping it enabled for at least 24 hours. If you don't BSOD by then, disable Driver Verifier. I will usually say whether or not I'd like for you to keep it enabled any longer.

My system BSOD'd with Driver Verifier enabled, where can I find the crash dumps?

They will be located in %systemroot%\Minidump

Patrick? That last post has the link for the folder with the actual files. The folder is labeled Mindump 2 (correct)

Oh, sorry about that. I do believe that this should be the actual files now.

These are shortcuts to the dumps, not the actual dumps themselves. Can you zip up the dumps themselves in safe mode, please?
