Frequent BSOD after W10 Anniv. update


Aug 17, 2015
I have an HP desktop which originally came with Vista. I upgraded it to Win8/8.1 without issues and also upgraded to Win10. After the Win10 Anniversary update was installed, I had the BSOD every 2 or 3 days. Most of my computer use is on the internet using Firefox (email, Facebook, google searches). The frequency of the BSOD has increased to the point that the computer is not usable. I have not seen any error codes but did have the message "DPC Watchdog Violation" at first and now "DriverVerifier Detection Violation"

Paul NZ: These were the only .dmp files and I have these three because I went in an renamed them from just MEMORY.DMP. Where are the small .dmp files that you are referring to? These were in C:\WINDOWS.

Someone else suggested that HitmanPro 37.sys was the culprit and I uninstalled HitmanPro37. After a reboot, the system has been running smoothly for more than 4 hours without any issues.

Thanks for your help.
it is a old machine (2008 bios) but the only bug I see is in the new antivirus software.
you can turn off verifier.exe using
verifier.exe /reset

or you can just exclude the driver from verifier testing.
note system was up 11 minutes 15 seconds before problem was detected in antivirus software driver.

bughceck just shows a bug in

SurfRight B.V. HitmanPro 3.7 Driver

Image name: hitmanpro37.sys

you have verifier running and it bugchecked because this driver is waiting on a Object but did not specify a timeout value.
verifer called a bugcheck because of it.

you can make verifier.exe excluede a driver for testing via /driver.exclude DriverList

so something like
verifier.exe /standard /all /driver.exclude hitmanpro37.sys

this should allow you to boot and and check other files for bugs while you wait for a update to your failing driver.

I will take a better look at the memory dump for other problems.
