    DPC Watchdog Violation

    Periodically getting DPC Watchdog Violation BSODS.
    Machine will run for a couple of hours then freeze and get BSOD, or System process taking large percentage of CPU.....


    PS I hope that I have attached the output file from log collector correctly !!

    It looks like the problem could be associated with a Glasswire Firewall product. Try temporarily removing this and using the built in W10 firewall. See if it makes a difference. If it does you can either continue with the W10 firewall or try to update the Glasswire drivers.

    Thanks Zboot for your input.
    Answers as follows:- Hosts file tidied up and guilty entries removed
    When I ran log-collector to show problems, there were errors on the Powershell screen which I could not catch. I have subsequently run DM_Log_Collector and the output is attached. It was interseting when running this that it reported that it could not find the minidump file.
    CCleaner image attached
    I do not have HD Clean but have HD Cleaner, however this will not load.

    Many Thanks

    1) For Ccleaner:
    a) uncheck Memory dumps
    b) uncheck Windows log files

    2) Check other installed software to see what can be done to prevent the cleaning of:
    a) Windows error reporting: WER
    b) Event logs

    3) If there are any BSOD immeidately:
    a) run the BETA log collector and post a new zip into the thread
    b) open file explorer > this PC > C: > in the right upper corner search for: C:\windows\memory.dmp > if the file size is < 1.5 GB then zip > post a share link into the thread using one drive, drop box, or google drive

    4) Please use the information in this link to unintall iobit software:
