    Getting DCP_Watchdog_violation errors related to Netwt04.sys


    I recently had to perform a fresh install of windows but have been experiencing a series of BSODs after a BIOS and Windows update ( version 19042.928 for 64 bit). Using WinDbd preview, I see from my mini dump files that most of them are related to the Netwt04.sys driver. I have an Intel(R) Dual Band Wireless-AC 7265 wifi card. I have updated my drivers either using Intel's Driver and Support Assistant, but it also gives me the same BSOD related to the network driver. I uninstall it, and I download the Intel network driver recommended by HP for my desktop here: https://support.hp.com/ca-en/drivers...Id/ob-256252-1

    I get BSoDs again. Could someone take a look at my dump files and see what is leading up to these crashes?
    I've also uploaded a png of computer specs. Model 750-539cb HP Desktop Envy

    Thanks in advance!

    Thank you for the suggestion; was there anything in the logs indicating this was the culprit? Genuinely curious because I did have a hunch this was the other culprit but didnít have anything to confirm the suspicion.

    For the last crash dump recorded in the logs try !dpcs in WinDBG. [The !dpcs extension displays the deferred procedure call (DPC) queues]

    Code:

    Thank you guys so much; I'll do the update and see if anything pop ups

    - - - Updated - - -

    I had updated the NVIDIA driver as linked in the post above, but I fear I just received another DCP watchdog violation error related to WppRecorder.sys just an hour upon booting up the computer. I had up a youtube video on chrome, so I don't think it was anything demanding. I'll enclose the dump files from the most recent crash. Thank you in advance. Should I be rolling it back?

    - - - Updated - - -

    Unfortunately, updating the NVIDIA driver did not stop the BSODs; most of them are related to the Netwtw04.sys driver. I'll enclose some new minidump files (although one was unable to load/save/write because the BSOD occurred before it was finished writing).

    - - - Updated - - -

    I have resorted to disabling my network adapter to see if it would alleviate the issues and operate using an ethernet cable. Unfortunately, I ended up getting another BSOD related to rt640x64.sys instead. Enclosed is the minidump.

    There are multiple crashes with different causes so to fix these problems you are going to need to update several drivers. The network drivers are netwtw04.sys and rt640x64.sys. The HP provided drivers may no longer be compatible with the latest Windows updates and so you may need to wait for an update from HP or try the versions directly from Intel and Realtek as you have been doing. Unfortunately this is a trial and error process.

    Currently you have the following installed:
    Netwtw04.sys Tue Dec 29 18:32:30 2020 - this one looks different to the HP website version
    rt640x64.sys Tue Jun 27 09:42:46 2017 - this is the same as on the HP website.
    nvlddmkm.sys Mon Apr 12 20:54:45 2021 - this is not the same as on the HP website but the only one there is for an older version of Windows. Again it will be trial and error finding the right one without help from HP.
