  1. Hey, I'm new here and I need help on this BSOD that keeps randomly appearing when I boot up my computer. It keeps saying irql_not _less _or_equal. I've uninstalled and reinstalled most of my programs, updated the computer, and checked for malware, but it still keeps showing every few days.

    Can somebody help? Also, I don't know how to get file permissions to upload the minidump files.

    Hello Khaoz

    Please attach latest five (5) minidumps with your next post after zipping them in a single file for analysis. You can find these in C:\windows\minidump.

    All of your crashes has been caused by Mcafee AV (installed on your PC) driver mfetdik.sys. I would suggest that you should uninstall Mcafee.

    For completely removing Mcafee follow this link.

    As replacement AV, I would suggest you to have a look at MSE or Avast or Avira.

    Thanks. I've uninstalled it and got AVG. I'll keep posting if I have any more problems.

    hello fish
    Please start your own thread so you can get all the help you need.

    Also you need to tell your system's specifications and whether you are running a RAID setup or not?
