  1. In case in task manager CPU is jumping to 100%
    and system is crashing with BSOD then move the ddkmd.sys from C: Windows System32 drivers to your Desktop and then boot the system , it will work normally as this file creates an issue and not finding the HW will keep increasing CPU to 100%.

    Don’t worry in worst case scenario – you can still boot in safe mode and bring back the file to original location . 🙂

    Good Luck !!!
