  1. I did all this plus cleaned and reseated my RAM, did a BIOS update and Windows update. The error stopped for two days after the BIOS and Windows update then resumed when I restarted my PC. I’ve been struggling with this for a week and its driving me crazy.

  2. Hi thanks for this, it gave me a starting point but i scratched my head for hours and kept coming back to it, but my system blue screened at the most in opportune moments, and i was on the verge of resetting windows when i found it, my antivirus has an extension i can install in my browsers, but it seems Firefox and im not sure if google has it also, that blocks web pages it suspects of being Malicious, well my web page extension does it also, so i think they were having a dust up in the background, ive disabled the extensions and i havent had a BSOD since, one other thing i had Xsplit installed that i dont really use, a broadcast service for games, so if people get stumped like i was might be worth looking at those also

  3. I see what you did there.
    (Method 3 disables the service so the error won’t ever come up again… lol but now you don’t have that service available…)
