Just received a Blue screen with the Stop Code: DPC_WATCHDOG_VIOLATION.

 

Computer has been running normally up until this blue screen. 

 

Can anyone help with how to fix this or what the issue is.

 

Many Thanks.

Hi,

 

I clicked on your 1st link and it mentioned IDE ATA/ATAPI controller in Device Manager list, I do not have this on my list.

 

I did run an SFC scan through command prompt and have upload the CBS log below. I did this straight after I got the blue screen.

For sure, this issue can be caused by various reasons such as outdated drives, unsupported firmware, software and hardware incompatibility issues and so on.

Perhaps someone else here has something else to propose if nothing above works.

Hi,

 

So what I did was I downloaded AVG Driver update and ran a scan and it updated a load of drivers. I also ran a windows update as well which didn't have an updates for me to run.

 

Also did the Check and Fix Disk Errors option and it didn't find any issues. 

 

Also ran the SFC scan again and it said it didn't find any integrity issues. 

 

Could the initial SFC scan after the blue screen, that found something, been fixed through that or is that impossible? I just want to try and fix it so I don't get a blue screen. 

 

Would the drivers just change like that from one minute to become an issue and would simply updated the drivers get rid of a blue screen error?

Well, at the Security Forum we do not recommend the use of Drivers updaters as this can be done via the Windows. I would recommend you to uninstall AVG Driver Updater now.
 
 

Also did the Check and Fix Disk Errors option and it didn't find any issues.

 
You mean that you ran the chkdsk utility?

Of course. This can be possible. Do you have Windows 10? If yes, you may consider to run DISM before SFC.
 

• Click on the Start button and in the search box, type Command Prompt
• When you see Command Prompt on the list, right-click on it and select Run as administrator
• Enter the command below and press on Enter;

DISM /Online /Cleanup-Image /RestoreHealth

• Let the scan run until the end (100%). Depending on your system, it can take some time.
• Please post here the result you got.

 

When DISM finishes, you can then run SFC from the same command prompt window, but full instructions as if starting fresh:

• Click on the Start button and in the search box, type Command Prompt
• When you see Command Prompt on the list, right-click on it and select Run as administrator
• Enter the command below and press on Enter

sfc /scannow

• Let the scan finish.
• You will normally get one of the following results:
  

  Windows Resource Protection did not find any integrity violations
  Windows Resource Protection found corrupt files and successfully repaired them
  Windows Resource Protection found corrupt files but was unable to fix some of them
  Windows Resource Protection could not perform the requested operation
  

• Please post the result you got.

Hi,

 

Can I ask how you would normally update your drivers?

 

I ran the chkdsk utility last night and it didn't through anything up.

 

I do indeed have Windows 10.

 

Here are the results of DISM /Online /Cleanup-Image /RestoreHealth below:

 

Deployment Image Servicing and Management tool

Version: 10.0.19041.844

 

Image Version: 10.0.19043.1083

 

[==========================100.0%==========================] The restore operation completed successfully.

The operation completed successfully.

 

I then carried out an additionally SFC scan after the above step. Please see results below:

 

 

C:\Windows\system32>sfc /scannow

 

Beginning system scan.  This process will take some time.

 

Beginning verification phase of system scan.

Verification 100% complete.

 

Windows Resource Protection did not find any integrity violations.

 

C:\Windows\system32>

The SFC outcome is good, no corruptions were found.

 

As for the drivers:

 

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. If you are running the latest Windows updates, then you probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, you can do that via Device Manager.

 

See here:

 

Update drivers in Windows 10 (microsoft.com)

OK. So it all looks good. You think the issue may have been the drivers or whatever was found in that initial SFC scan?

 

I do regularly check windows update and instal driver updates but obviously something went wrong. I did check the event viewer and I am still getting yellow and red warnings is this normal ?

 

Thanks for your help, hope that's the end of the blue screen.

That is very possible, especially after you said that the initial scan found and fixed corruptions. Let us know if the blue screen returns any time.

I hope that too.

 

You are very welcome.
