    We do need the actual log files (called a DMP files) as they contain the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.  


    Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here
    If you have any questions about the procedure please ask

  • Hi,

    btfilter.sys seems to be a Bluetooth related file.

    As it is a device related file (should be a driver file), you should able to boot into Safe Mode.

    If so, uninstall your bluetooth device in Device Manager and see if you can boot back to normal mode. You can download and install a new driver for your device after reboot to normal mode.
